Chapter 4. Installing RHACS on Red Hat OpenShift 4.1. Installing Central services for RHACS on Red Hat OpenShift Central is the resource that contains the RHACS application management interface and services. It handles data persistence, API interactions, and RHACS portal access. You can use the same Central instance to secure multiple OpenShift Container Platform or Kubernetes clusters. You can install Central on your OpenShift Container Platform or Kubernetes cluster by using one of the following methods: Install using the Operator Install using Helm charts Install using the roxctl CLI (do not use this method unless you have a specific installation need that requires using it) 4.1.1. Install Central using the Operator 4.1.1.1. Installing the Red Hat Advanced Cluster Security for Kubernetes Operator Using the OperatorHub provided with OpenShift Container Platform is the easiest way to install Red Hat Advanced Cluster Security for Kubernetes. Prerequisites You have access to an OpenShift Container Platform cluster using an account with Operator installation permissions. You must be using OpenShift Container Platform 4.12 or later. For information about supported platforms and architecture, see the Red Hat Advanced Cluster Security for Kubernetes Support Matrix . For life cycle support information for RHACS, see the Red Hat Advanced Cluster Security for Kubernetes Support Policy . Procedure In the web console, go to the Operators OperatorHub page. If Red Hat Advanced Cluster Security for Kubernetes is not displayed, enter Advanced Cluster Security into the Filter by keyword box to find the Red Hat Advanced Cluster Security for Kubernetes Operator. Select the Red Hat Advanced Cluster Security for Kubernetes Operator to view the details page. Read the information about the Operator, and then click Install . On the Install Operator page: Keep the default value for Installation mode as All namespaces on the cluster . Choose a specific namespace in which to install the Operator for the Installed namespace field. Install the Red Hat Advanced Cluster Security for Kubernetes Operator in the rhacs-operator namespace. Select automatic or manual updates for Update approval . If you choose automatic updates, when a new version of the Operator is available, Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator. If you choose manual updates, when a newer version of the Operator is available, OLM creates an update request. As a cluster administrator, you must manually approve the update request to update the Operator to the latest version. Important If you choose manual updates, you must update the RHACS Operator in all secured clusters when you update the RHACS Operator in the cluster where Central is installed. The secured clusters and the cluster where Central is installed must have the same version to ensure optimal functionality. Click Install . Verification After the installation completes, go to Operators Installed Operators to verify that the Red Hat Advanced Cluster Security for Kubernetes Operator is listed with the status of Succeeded . Step You installed the Operator into the rhacs-operator project. Using that Operator, install, configure, and deploy the Central custom resource into the stackrox project. 4.1.1.2. Installing Central using the Operator method The main component of Red Hat Advanced Cluster Security for Kubernetes is called Central. You can install Central on OpenShift Container Platform by using the Central custom resource. You deploy Central only once, and you can monitor multiple separate clusters by using the same Central installation. Important When you install Red Hat Advanced Cluster Security for Kubernetes for the first time, you must first install the Central custom resource because the SecuredCluster custom resource installation is dependent on certificates that Central generates. Red Hat recommends installing the Red Hat Advanced Cluster Security for Kubernetes Central custom resource in a dedicated project. Do not install it in the project where you have installed the Red Hat Advanced Cluster Security for Kubernetes Operator. Additionally, do not install it in any projects with names that begin with kube , openshift , or redhat , and in the istio-system project. Prerequisites You must be using OpenShift Container Platform 4.12 or later. For information about supported platforms and architecture, see the Red Hat Advanced Cluster Security for Kubernetes Support Matrix . For life cycle support information for RHACS, see the Red Hat Advanced Cluster Security for Kubernetes Support Policy . Procedure On the OpenShift Container Platform web console, go to the Operators Installed Operators page. Select the Red Hat Advanced Cluster Security for Kubernetes Operator from the list of installed Operators. If you have installed the Operator in the recommended namespace, OpenShift Container Platform lists the project as rhacs-operator . Select Project: rhacs-operator Create project . Note If you installed the Operator in a different namespace, OpenShift Container Platform lists the name of that namespace instead of rhacs-operator . Enter the new project name (for example, stackrox ), and click Create . Red Hat recommends that you use stackrox as the project name. Under the Provided APIs section, select Central . Click Create Central . Optional: If you are using declarative configuration, to Configure via: , click YAML view and add the information for the declarative configuration, such as shown in the following example: ... spec: central: declarativeConfiguration: configMaps: - name: "<declarative-configs>" 1 secrets: - name: "<sensitive-declarative-configs>" 2 ... 1 Replace <declarative-configs> with the name of the config maps that you are using. 2 Replace <sensitive-declarative-configs> with the name of the secrets that you are using. Enter a name for your Central custom resource and add any labels you want to apply. Otherwise, accept the default values for the available options. You can configure available options for Central: Central component settings: Setting Description Administrator password Secret that contains the administrator password. Use this field if you do not want RHACS to generate a password for you. Exposure Settings for exposing Central by using a route, load balancer, or node port. See the central.exposure.<parameter> information in the "Public configuration file" section in "Installing Central services for RHACS on Red Hat OpenShift". User-facing TLS certificate secret Use this field if you want to terminate TLS in Central and serve a custom server certificate. Monitoring Configures the monitoring endpoint for Central. See the central.exposeMonitoring parameter in the "Public configuration file" section in "Installing Central services for RHACS on Red Hat OpenShift". Central DB Settings Settings for Central DB, including data persistence. See the central.db.<parameter> information in the "Public configuration file" section in "Installing Central services for RHACS on Red Hat OpenShift". Resources Use these fields after consulting the documentation if you need to override the default settings for memory and CPU resources. For more information, see the "Default resource requirements for RHACS" and "Recommended resource requirements for RHACS" sections in the "Installation" chapter. Tolerations Use this parameter to configure Central to run only on specific nodes. See the central.tolerations parameter in the "Public configuration file" section in "Installing Central services for RHACS on Red Hat OpenShift". Host Aliases Use this parameter to configure additional hostnames to resolve in the pod's hosts file. Scanner Component Settings : Settings for the default scanner, also called the StackRox Scanner. See the "Scanner" table in the "Public configuration file" section in "Installing Central services for RHACS on Red Hat OpenShift". Scanner V4 Component Settings : Settings for the optional Scanner V4 scanner, available in version 4.4 and later. It is not currently enabled by default. You can enable both the StackRox Scanner and Scanner V4 for concurrent use. See the "Scanner V4" table in the "Public configuration file" section in "Installing Central services for RHACS on Red Hat OpenShift". When Scanner V4 is enabled, you can configure the following options: Setting Description Indexer The process that indexes images and creates a report of findings. You can configure replicas and autoscaling, resources, and tolerations. Before changing the default resource values, see the "Scanner V4" sections in the "Default resource requirements for RHACS" and "Recommended resource requirements for RHACS" sections in the "Installation" chapter. Matcher The process that performs vulnerability matching of the report from the indexer against vulnerability data stored in Scanner V4 DB. You can configure replicas and autoscaling, resources, and tolerations. Before changing the default resource values, see the "Scanner V4" sections in the "Default resource requirements for RHACS" and "Recommended resource requirements for RHACS" sections in the "Installation" chapter. DB The database that stores information for Scanner V4, including vulnerability data and index reports. You can configure persistence, resources, and tolerations. If you are using Scanner V4, a persistent volume claim (PVC) is required on Central clusters. A PVC is strongly recommended on secured clusters for best results. Before changing the default resource values, see the "Scanner V4" sections in the "Default resource requirements for RHACS" and "Recommended resource requirements for RHACS" sections in the "Installation" chapter. Egress : Settings for outgoing network traffic, including whether RHACS should run in online (connected) or offline (disconnected) mode. TLS : Use this field to add additional trusted root certificate authorities (CAs). network : To provide security at the network level, RHACS creates default NetworkPolicy resources in the namespace where Central is installed. To create and manage your own network policies, in the policies section, select Disabled . By default, this option is Enabled . Warning Disabling creation of default network policies can break communication between RHACS components. If you disable creation of default policies, you must create your own network policies to allow this communication. Advanced configuration : You can use these fields to perform the following actions: Specify additional image pull secrets Add custom environment variables to set for managed pods' containers Enable Red Hat OpenShift monitoring Click Create . Note If you are using the cluster-wide proxy, Red Hat Advanced Cluster Security for Kubernetes uses that proxy configuration to connect to the external services. Steps Verify Central installation. Optional: Configure Central options. Generate an init bundle containing the cluster secrets that allows communication between the Central and SecuredCluster resources. You need to download this bundle, use it to generate resources on the clusters you want to secure, and securely store it. Install secured cluster services on each cluster you want to monitor. Additional resources Default resource requirements for Red Hat Advanced Cluster Security for Kubernetes Recommended resource requirements for Red Hat Advanced Cluster Security for Kubernetes Public configuration file 4.1.1.3. Provisioning a database in your PostgreSQL instance This step is optional. You can use your existing PostgreSQL infrastructure to provision a database for RHACS. Use the instructions in this section for configuring a PostgreSQL database environment, creating a user, database, schema, role, and granting required permissions. Procedure Create a new user: CREATE USER stackrox WITH PASSWORD <password>; Create a database: CREATE DATABASE stackrox; Connect to the database: \connect stackrox Create user schema: CREATE SCHEMA stackrox; (Optional) Revoke rights on public: REVOKE CREATE ON SCHEMA public FROM PUBLIC; REVOKE USAGE ON SCHEMA public FROM PUBLIC; REVOKE ALL ON DATABASE stackrox FROM PUBLIC; Create a role: CREATE ROLE readwrite; Grant connection permission to the role: GRANT CONNECT ON DATABASE stackrox TO readwrite; Add required permissions to the readwrite role: GRANT USAGE ON SCHEMA stackrox TO readwrite; GRANT USAGE, CREATE ON SCHEMA stackrox TO readwrite; GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA stackrox TO readwrite; ALTER DEFAULT PRIVILEGES IN SCHEMA stackrox GRANT SELECT, INSERT, UPDATE, DELETE ON TABLES TO readwrite; GRANT USAGE ON ALL SEQUENCES IN SCHEMA stackrox TO readwrite; ALTER DEFAULT PRIVILEGES IN SCHEMA stackrox GRANT USAGE ON SEQUENCES TO readwrite; Assign the readwrite role to the stackrox user: GRANT readwrite TO stackrox; 4.1.1.4. Installing Central with an external database using the Operator method The main component of Red Hat Advanced Cluster Security for Kubernetes is called Central. You can install Central on OpenShift Container Platform by using the Central custom resource. You deploy Central only once, and you can monitor multiple separate clusters by using the same Central installation. Important When you install Red Hat Advanced Cluster Security for Kubernetes for the first time, you must first install the Central custom resource because the SecuredCluster custom resource installation is dependent on certificates that Central generates. For more information about RHACS databases, see the Database Scope of Coverage . Prerequisites You must be using OpenShift Container Platform 4.12 or later. For more information about supported OpenShift Container Platform versions, see the Red Hat Advanced Cluster Security for Kubernetes Support Matrix . You must have a database in your database instance that supports PostgreSQL 13 and a user with the following permissions: Connection rights to the database. Usage and Create on the schema. Select , Insert , Update , and Delete on all tables in the schema. Usage on all sequences in the schema. Procedure On the OpenShift Container Platform web console, go to the Operators Installed Operators page. Select the Red Hat Advanced Cluster Security for Kubernetes Operator from the list of installed Operators. If you have installed the Operator in the recommended namespace, OpenShift Container Platform lists the project as rhacs-operator . Select Project: rhacs-operator Create project . Warning If you have installed the Operator in a different namespace, OpenShift Container Platform shows the name of that namespace rather than rhacs-operator . Red Hat recommends installing the Red Hat Advanced Cluster Security for Kubernetes Central custom resource in a dedicated project. Do not install it in the project where you have installed the Red Hat Advanced Cluster Security for Kubernetes Operator. Additionally, do not install it in any projects with names that begin with kube , openshift , or redhat , and in the istio-system project. Enter the new project name (for example, stackrox ), and click Create . Red Hat recommends that you use stackrox as the project name. Create a password secret in the deployed namespace by using the OpenShift Container Platform web console or the terminal. On the OpenShift Container Platform web console, go to the Workloads Secrets page. Create a Key/Value secret with the key password and the value as the path of a plain text file containing the password for the superuser of the provisioned database. Or, run the following command in your terminal: USD oc create secret generic external-db-password \ 1 --from-file=password=<password.txt> 2 1 If you use Kubernetes, enter kubectl instead of oc . 2 Replace password.txt with the path of the file which has the plain text password. Return to the Red Hat Advanced Cluster Security for Kubernetes operator page in the OpenShift Container Platform web console. Under the Provided APIs section, select Central . Click Create Central . Optional: If you are using declarative configuration, to Configure via: , click YAML view . Add the information for the declarative configuration, such as shown in the following example: ... spec: central: declarativeConfiguration: configMaps: - name: <declarative-configs> 1 secrets: - name: <sensitive-declarative-configs> 2 ... 1 Replace <declarative-configs> with the name of the config maps that you are using. 2 Replace <sensitive-declarative-configs> with the name of the secrets that you are using. Enter a name for your Central custom resource and add any labels you want to apply. Go to Central Component Settings Central DB Settings . For Administrator Password specify the referenced secret as external-db-password (or the secret name of the password created previously). For Connection String specify the connection string in keyword=value format, for example, host=<host> port=5432 database=stackrox user=stackrox sslmode=verify-ca For Persistence PersistentVolumeClaim Claim Name , remove central-db . If necessary, you can specify a Certificate Authority so that there is trust between the database certificate and Central. To add this, go to the YAML view and add a TLS block under the top-level spec, as shown in the following example: spec: tls: additionalCAs: - name: db-ca content: | <certificate> Click Create . Note If you are using the cluster-wide proxy, Red Hat Advanced Cluster Security for Kubernetes uses that proxy configuration to connect to the external services. Steps Verify Central installation. Optional: Configure Central options. Generate an init bundle containing the cluster secrets that allows communication between the Central and SecuredCluster resources. You need to download this bundle, use it to generate resources on the clusters you want to secure, and securely store it. Install secured cluster services on each cluster you want to monitor. Additional resources Central configuration options PostgreSQL Connection String Docs 4.1.1.5. Verifying Central installation using the Operator method After Central finishes installing, log in to the RHACS portal to verify the successful installation of Central. Procedure On the OpenShift Container Platform web console, go to the Operators Installed Operators page. Select the Red Hat Advanced Cluster Security for Kubernetes Operator from the list of installed Operators. Select the Central tab. From the Centrals list, select stackrox-central-services to view its details. To get the password for the admin user, you can either: Click the link under Admin Password Secret Reference . Use the Red Hat OpenShift CLI to enter the command listed under Admin Credentials Info : USD oc -n stackrox get secret central-htpasswd -o go-template='{{index .data "password" | base64decode}}' Find the link to the RHACS portal by using the Red Hat OpenShift CLI command: USD oc -n stackrox get route central -o jsonpath="{.status.ingress[0].host}" Alternatively, you can use the Red Hat Advanced Cluster Security for Kubernetes web console to find the link to the RHACS portal by performing the following commands: Go to Networking Routes . Find the central Route and click on the RHACS portal link under the Location column. Log in to the RHACS portal using the username admin and the password that you retrieved in a step. Until RHACS is completely configured (for example, you have the Central resource and at least one SecuredCluster resource installed and configured), no data is available in the dashboard. The SecuredCluster resource can be installed and configured on the same cluster as the Central resource. Clusters with the SecuredCluster resource are similar to managed clusters in Red Hat Advanced Cluster Management (RHACM). Steps Optional: Configure central settings. Generate an init bundle containing the cluster secrets that allows communication between the Central and SecuredCluster resources. You need to download this bundle, use it to generate resources on the clusters you want to secure, and securely store it. Install secured cluster services on each cluster you want to monitor. 4.1.2. Install Central using Helm charts You can install Central using Helm charts without any customization, using the default values, or by using Helm charts with additional customizations of configuration parameters. 4.1.2.1. Install Central using Helm charts without customization You can install RHACS on your cluster without any customizations. You must add the Helm chart repository and install the central-services Helm chart to install the centralized components of Central and Scanner. 4.1.2.1.1. Adding the Helm chart repository Procedure Add the RHACS charts repository. USD helm repo add rhacs https://mirror.openshift.com/pub/rhacs/charts/ The Helm repository for Red Hat Advanced Cluster Security for Kubernetes includes Helm charts for installing different components, including: Central services Helm chart ( central-services ) for installing the centralized components (Central and Scanner). Note You deploy centralized components only once and you can monitor multiple separate clusters by using the same installation. Secured Cluster Services Helm chart ( secured-cluster-services ) for installing the per-cluster and per-node components (Sensor, Admission Controller, Collector, and Scanner-slim). Note Deploy the per-cluster components into each cluster that you want to monitor and deploy the per-node components in all nodes that you want to monitor. Verification Run the following command to verify the added chart repository: USD helm search repo -l rhacs/ 4.1.2.1.2. Installing the central-services Helm chart without customizations Use the following instructions to install the central-services Helm chart to deploy the centralized components (Central and Scanner). Prerequisites You must have access to the Red Hat Container Registry. For information about downloading images from registry.redhat.io , see Red Hat Container Registry Authentication . Procedure Run the following command to install Central services and expose Central using a route: USD helm install -n stackrox \ --create-namespace stackrox-central-services rhacs/central-services \ --set imagePullSecrets.username=<username> \ 1 --set imagePullSecrets.password=<password> \ 2 --set central.exposure.route.enabled=true 1 Include the user name for your pull secret for Red Hat Container Registry authentication. 2 Include the password for your pull secret for Red Hat Container Registry authentication. Or, run the following command to install Central services and expose Central using a load balancer: USD helm install -n stackrox \ --create-namespace stackrox-central-services rhacs/central-services \ --set imagePullSecrets.username=<username> \ 1 --set imagePullSecrets.password=<password> \ 2 --set central.exposure.loadBalancer.enabled=true 1 Include the user name for your pull secret for Red Hat Container Registry authentication. 2 Include the password for your pull secret for Red Hat Container Registry authentication. Or, run the following command to install Central services and expose Central using port forward: USD helm install -n stackrox \ --create-namespace stackrox-central-services rhacs/central-services \ --set imagePullSecrets.username=<username> \ 1 --set imagePullSecrets.password=<password> 2 1 Include the user name for your pull secret for Red Hat Container Registry authentication. 2 Include the password for your pull secret for Red Hat Container Registry authentication. Important If you are installing Red Hat Advanced Cluster Security for Kubernetes in a cluster that requires a proxy to connect to external services, you must specify your proxy configuration by using the proxyConfig parameter. For example: env: proxyConfig: | url: http://proxy.name:port username: username password: password excludes: - some.domain If you already created one or more image pull secrets in the namespace in which you are installing, instead of using a username and password, you can use --set imagePullSecrets.useExisting="<pull-secret-1;pull-secret-2>" . Do not use image pull secrets: If you are pulling your images from quay.io/stackrox-io or a registry in a private network that does not require authentication. Use use --set imagePullSecrets.allowNone=true instead of specifying a username and password. If you already configured image pull secrets in the default service account in the namespace you are installing. Use --set imagePullSecrets.useFromDefaultServiceAccount=true instead of specifying a username and password. The output of the installation command includes: An automatically generated administrator password. Instructions on storing all the configuration values. Any warnings that Helm generates. 4.1.2.2. Install Central using Helm charts with customizations You can install RHACS on your Red Hat OpenShift cluster with customizations by using Helm chart configuration parameters with the helm install and helm upgrade commands. You can specify these parameters by using the --set option or by creating YAML configuration files. Create the following files for configuring the Helm chart for installing Red Hat Advanced Cluster Security for Kubernetes: Public configuration file values-public.yaml : Use this file to save all non-sensitive configuration options. Private configuration file values-private.yaml : Use this file to save all sensitive configuration options. Ensure that you store this file securely. Configuration file declarative-config-values.yaml : Create this file if you are using declarative configuration to add the declarative configuration mounts to Central. 4.1.2.2.1. Private configuration file This section lists the configurable parameters of the values-private.yaml file. There are no default values for these parameters. 4.1.2.2.1.1. Image pull secrets The credentials that are required for pulling images from the registry depend on the following factors: If you are using a custom registry, you must specify these parameters: imagePullSecrets.username imagePullSecrets.password image.registry If you do not use a username and password to log in to the custom registry, you must specify one of the following parameters: imagePullSecrets.allowNone imagePullSecrets.useExisting imagePullSecrets.useFromDefaultServiceAccount Parameter Description imagePullSecrets.username The username of the account that is used to log in to the registry. imagePullSecrets.password The password of the account that is used to log in to the registry. imagePullSecrets.allowNone Use true if you are using a custom registry and it allows pulling images without credentials. imagePullSecrets.useExisting A comma-separated list of secrets as values. For example, secret1, secret2, secretN . Use this option if you have already created pre-existing image pull secrets with the given name in the target namespace. imagePullSecrets.useFromDefaultServiceAccount Use true if you have already configured the default service account in the target namespace with sufficiently scoped image pull secrets. 4.1.2.2.1.2. Proxy configuration If you are installing Red Hat Advanced Cluster Security for Kubernetes in a cluster that requires a proxy to connect to external services, you must specify your proxy configuration by using the proxyConfig parameter. For example: env: proxyConfig: | url: http://proxy.name:port username: username password: password excludes: - some.domain Parameter Description env.proxyConfig Your proxy configuration. 4.1.2.2.1.3. Central Configurable parameters for Central. For a new installation, you can skip the following parameters: central.jwtSigner.key central.serviceTLS.cert central.serviceTLS.key central.adminPassword.value central.adminPassword.htpasswd central.db.serviceTLS.cert central.db.serviceTLS.key central.db.password.value When you do not specify values for these parameters the Helm chart autogenerates values for them. If you want to modify these values you can use the helm upgrade command and specify the values using the --set option. Important For setting the administrator password, you can only use either central.adminPassword.value or central.adminPassword.htpasswd , but not both. Parameter Description central.jwtSigner.key A private key which RHACS should use for signing JSON web tokens (JWTs) for authentication. central.serviceTLS.cert An internal certificate that the Central service should use for deploying Central. central.serviceTLS.key The private key of the internal certificate that the Central service should use. central.defaultTLS.cert The user-facing certificate that Central should use.

Set its value to default or gke to specify cluster platform and override automatic cluster environment detection. env.offlineMode Use true to use RHACS in offline mode. 4.1.2.2.2.5. Additional trusted certificate authorities The RHACS automatically references the system root certificates to trust. When Central, the StackRox Scanner, or Scanner V4 must reach out to services that use certificates issued by an authority in your organization or a globally trusted partner organization, you can add trust for these services by specifying the root certificate authority to trust by using the following parameter: Parameter Description additionalCAs.<certificate_name> Specify the PEM encoded certificate of the root certificate authority to trust. 4.1.2.2.2.6. Default network policies To provide security at the network level, RHACS creates default NetworkPolicy resources in the namespace where Central is installed. These network policies allow ingress to specific components on specific ports. If you do not want RHACS to create these policies, set this parameter to Disabled . The default value is Enabled . Warning Disabling creation of default network policies can break communication between RHACS components. If you disable creation of default policies, you must create your own network policies to allow this communication. Parameter Description network.enableNetworkPolicies Specify if RHACS creates default network policies to allow communication between components. To create your own network policies, set this parameter to False . The default value is True . 4.1.2.2.2.7. Central Configurable parameters for Central. For exposing Central deployment for external access. You must specify one parameter, either central.exposure.loadBalancer , central.exposure.nodePort , or central.exposure.route .

Advanced customization Important The parameters specified in this section are for information only. Red Hat does not support RHACS instances with modified namespace and release names. Parameter Description allowNonstandardNamespace Use true to deploy RHACS into a namespace other than the default namespace stackrox . allowNonstandardReleaseName Use true to deploy RHACS with a release name other than the default stackrox-central-services . 4.1.2.2.3. Declarative configuration values To use declarative configuration, you must create a YAML file (in this example, named "declarative-config-values.yaml") that adds the declarative configuration mounts to Central. This file is used in a Helm installation. Procedure Create the YAML file (in this example, named declarative-config-values.yaml ) using the following example as a guideline: central: declarativeConfiguration: mounts: configMaps: - declarative-configs secrets: - sensitive-declarative-configs Install the Central services Helm chart as documented in the "Installing the central-services Helm chart", referencing the declarative-config-values.yaml file. 4.1.2.2.4. Installing the central-services Helm chart After you configure the values-public.yaml and values-private.yaml files, install the central-services Helm chart to deploy the centralized components (Central and Scanner). Procedure Run the following command: USD helm install -n stackrox --create-namespace \ stackrox-central-services rhacs/central-services \ -f <path_to_values_public.yaml> -f <path_to_values_private.yaml> 1 1 Use the -f option to specify the paths for your YAML configuration files. Note Optional: If using declarative configuration, add -f <path_to_declarative-config-values.yaml to this command to mount the declarative configurations file in Central. 4.1.2.3. Changing configuration options after deploying the central-services Helm chart You can make changes to any configuration options after you have deployed the central-services Helm chart. When using the helm upgrade command to make changes, the following guidelines and requirements apply: You can also specify configuration values using the --set or --set-file parameters. However, these options are not saved, and you must manually specify all the options again whenever you make changes. Some changes, such as enabling a new component like Scanner V4, require new certificates to be issued for the component. Therefore, you must provide a CA when making these changes. If the CA was generated by the Helm chart during the initial installation, you must retrieve these automatically generated values from the cluster and provide them to the helm upgrade command. The post-installation notes of the central-services Helm chart include a command for retrieving the automatically generated values. If the CA was generated outside of the Helm chart and provided during the installation of the central-services chart, then you must perform that action again when using the helm upgrade command, for example, by using the --reuse-values flag with the helm upgrade command. Procedure Update the values-public.yaml and values-private.yaml configuration files with new values. Run the helm upgrade command and specify the configuration files using the -f option: USD helm upgrade -n stackrox \ stackrox-central-services rhacs/central-services \ --reuse-values \ 1 -f <path_to_init_bundle_file \ -f <path_to_values_public.yaml> \ -f <path_to_values_private.yaml> 1 If you have modified values that are not included in the values_public.yaml and values_private.yaml files, include the --reuse-values parameter. 4.1.3. Install Central using the roxctl CLI Warning For production environments, Red Hat recommends using the Operator or Helm charts to install RHACS. Do not use the roxctl install method unless you have a specific installation need that requires using this method. 4.1.3.1. Installing the roxctl CLI To install Red Hat Advanced Cluster Security for Kubernetes you must install the roxctl CLI by downloading the binary. You can install roxctl on Linux, Windows, or macOS. 4.1.3.1.1. Installing the roxctl CLI on Linux You can install the roxctl CLI binary on Linux by using the following procedure. Note roxctl CLI for Linux is available for amd64 , arm64 , ppc64le , and s390x architectures. Procedure Determine the roxctl architecture for the target operating system: USD arch="USD(uname -m | sed "s/x86_64//")"; arch="USD{arch:+-USDarch}" Download the roxctl CLI: USD curl -L -f -o roxctl "https://mirror.openshift.com/pub/rhacs/assets/4.6.3/bin/Linux/roxctlUSD{arch}" Make the roxctl binary executable: USD chmod +x roxctl Place the roxctl binary in a directory that is on your PATH : To check your PATH , execute the following command: USD echo USDPATH Verification Verify the roxctl version you have installed: USD roxctl version 4.1.3.1.2. Installing the roxctl CLI on macOS You can install the roxctl CLI binary on macOS by using the following procedure. Note roxctl CLI for macOS is available for amd64 and arm64 architectures. Procedure Determine the roxctl architecture for the target operating system: USD arch="USD(uname -m | sed "s/x86_64//")"; arch="USD{arch:+-USDarch}" Download the roxctl CLI: USD curl -L -f -o roxctl "https://mirror.openshift.com/pub/rhacs/assets/4.6.3/bin/Darwin/roxctlUSD{arch}" Remove all extended attributes from the binary: USD xattr -c roxctl Make the roxctl binary executable: USD chmod +x roxctl Place the roxctl binary in a directory that is on your PATH : To check your PATH , execute the following command: USD echo USDPATH Verification Verify the roxctl version you have installed: USD roxctl version 4.1.3.1.3. Installing the roxctl CLI on Windows You can install the roxctl CLI binary on Windows by using the following procedure. Note roxctl CLI for Windows is available for the amd64 architecture. Procedure Download the roxctl CLI: USD curl -f -O https://mirror.openshift.com/pub/rhacs/assets/4.6.3/bin/Windows/roxctl.exe Verification Verify the roxctl version you have installed: USD roxctl version 4.1.3.2. Using the interactive installer Use the interactive installer to generate the required secrets, deployment configurations, and deployment scripts for your environment. Procedure Run the interactive install command: USD roxctl central generate interactive Important Installing RHACS using the roxctl CLI creates PodSecurityPolicy (PSP) objects by default for backward compatibility. If you install RHACS on Kubernetes versions 1.25 and newer or OpenShift Container Platform version 4.12 and newer, you must disable the PSP object creation. To do this, specify --enable-pod-security-policies option as false for the roxctl central generate and roxctl sensor generate commands. Press Enter to accept the default value for a prompt or enter custom values as required. The following example shows the interactive installer prompts: Path to the backup bundle from which to restore keys and certificates (optional): PEM cert bundle file (optional): 1 Disable the administrator password (only use this if you have already configured an IdP for your instance) (default: "false"): Create PodSecurityPolicy resources (for pre-v1.25 Kubernetes) (default: "false"): 2 Administrator password (default: autogenerated): Orchestrator (k8s, openshift): Default container images settings (rhacs, opensource); it controls repositories from where to download the images, image names and tags format (default: "rhacs"): The directory to output the deployment bundle to (default: "central-bundle"): Whether to enable telemetry (default: "true"): The central-db image to use (if unset, a default will be used according to --image-defaults) (default: "registry.redhat.io/advanced-cluster-security/rhacs-central-db-rhel8:4.6.0"): List of secrets to add as declarative configuration mounts in central (default: "[]"): 3 The method of exposing Central (lb, np, none) (default: "none"): 4 The main image to use (if unset, a default will be used according to --image-defaults) (default: "registry.redhat.io/advanced-cluster-security/rhacs-main-rhel8:4.6.0"): Whether to run StackRox in offline mode, which avoids reaching out to the Internet (default: "false"): List of config maps to add as declarative configuration mounts in central (default: "[]"): 5 The deployment tool to use (kubectl, helm, helm-values) (default: "kubectl"): Istio version when deploying into an Istio-enabled cluster (leave empty when not running Istio) (optional): The scanner-db image to use (if unset, a default will be used according to --image-defaults) (default: "registry.redhat.io/advanced-cluster-security/rhacs-scanner-db-rhel8:4.6.0"): The scanner image to use (if unset, a default will be used according to --image-defaults) (default: "registry.redhat.io/advanced-cluster-security/rhacs-scanner-rhel8:4.6.0"): The scanner-v4-db image to use (if unset, a default will be used according to --image-defaults) (default: "registry.redhat.io/advanced-cluster-security/rhacs-scanner-v4-db-rhel8:4.6.0"): The scanner-v4 image to use (if unset, a default will be used according to --image-defaults) (default: "registry.redhat.io/advanced-cluster-security/rhacs-scanner-v4-rhel8:4.6.0"): External volume type (hostpath, pvc): hostpath Path on the host (default: "/var/lib/stackrox-central"): Node selector key (e.g. kubernetes.io/hostname): Node selector value: 1 If you want to add a custom TLS certificate, provide the file path for the PEM-encoded certificate. When you specify a custom certificate the interactive installer also prompts you to provide a PEM private key for the custom certificate you are using. 2 If you are running Kubernetes version 1.25 or later, set this value to false . 3 For more information on using declarative configurations for authentication and authorization, see "Declarative configuration for authentication and authorization resources" in "Managing RBAC in Red Hat Advanced Cluster Security for Kubernetes". 4 To use the RHACS portal, you must expose Central by using a route, a load balancer or a node port. 5 For more information on using declarative configurations for authentication and authorization, see "Declarative configuration for authentication and authorization resources" in "Managing RBAC in Red Hat Advanced Cluster Security for Kubernetes". Warning On OpenShift Container Platform, for using a hostPath volume, you must modify the SELinux policy to allow access to the directory, which the host and the container share. It is because SELinux blocks directory sharing by default. To modify the SELinux policy, run the following command: USD sudo chcon -Rt svirt_sandbox_file_t <full_volume_path> However, Red Hat does not recommend modifying the SELinux policy, instead use PVC when installing on OpenShift Container Platform. On completion, the installer creates a folder named central-bundle, which contains the necessary YAML manifests and scripts to deploy Central. In addition, it shows on-screen instructions for the scripts you need to run to deploy additional trusted certificate authorities, Central and Scanner, and the authentication instructions for logging into the RHACS portal along with the autogenerated password if you did not provide one when answering the prompts. 4.1.3.3. Running the Central installation scripts After you run the interactive installer, you can run the setup.sh script to install Central. Procedure Run the setup.sh script to configure image registry access: USD ./central-bundle/central/scripts/setup.sh To enable the policy as code feature (Technology Preview), manually apply the config.stackrox.io CRD that is located in the .zip file at helm/chart/crds/config.stackrox.io_securitypolicies.yaml . Important Policy as code is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope . To apply the CRD, run the following command: USD oc create -f helm/chart/crds/config.stackrox.io_securitypolicies.yaml Create the necessary resources: USD oc create -R -f central-bundle/central Check the deployment progress: USD oc get pod -n stackrox -w After Central is running, find the RHACS portal IP address and open it in your browser. Depending on the exposure method you selected when answering the prompts, use one of the following methods to get the IP address. Exposure method Command Address Example Route oc -n stackrox get route central The address under the HOST/PORT column in the output https://central-stackrox.example.route Node Port oc get node -owide && oc -n stackrox get svc central-loadbalancer IP or hostname of any node, on the port shown for the service https://198.51.100.0:31489 Load Balancer oc -n stackrox get svc central-loadbalancer EXTERNAL-IP or hostname shown for the service, on port 443 https://192.0.2.0 None central-bundle/central/scripts/port-forward.sh 8443 https://localhost:8443 https://localhost:8443 Note If you have selected autogenerated password during the interactive install, you can run the following command to see it for logging into Central: USD cat central-bundle/password 4.2. Configuring Central configuration options for RHACS using the Operator When installing the Central instance by using the Operator, you can configure optional settings. 4.2.1. Central configuration options using the Operator When you create a Central instance, the Operator lists the following configuration options for the Central custom resource. The following table includes settings for an external PostgreSQL database. 4.2.1.1. Central settings Parameter Description central.adminPasswordSecret Specify a secret that contains the administrator password in the password data item. If omitted, the operator autogenerates a password and stores it in the password item in the central-htpasswd secret. central.defaultTLSSecret By default, Central only serves an internal TLS certificate, which means that you need to handle TLS termination at the ingress or load balancer level. If you want to terminate TLS in Central and serve a custom server certificate, you can specify a secret containing the certificate and private key. central.adminPasswordGenerationDisabled Set this parameter to true to disable the automatic administrator password generation. Use this only after you perform the first-time setup of alternative authentication methods. Do not use this for initial installation. Otherwise, you must reinstall the custom resource to log back in. central.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Central. This parameter is mainly used for infrastructure nodes. central.hostAliases Use this parameter to inject hosts and IP addresses into the pod's hosts file. central.exposure.loadBalancer.enabled Set this to true to expose Central through a load balancer. central.exposure.loadBalancer.port Use this parameter to specify a custom port for your load balancer. central.exposure.loadBalancer.ip Use this parameter to specify a static IP address reserved for your load balancer. central.exposure.route.enabled Set this to true to expose Central through a Red Hat OpenShift route. The default value is false . central.exposure.route.host Specify a custom hostname to use for Central's route. Leave this unset to accept the default value that OpenShift Container Platform provides. central.exposure.nodeport.enabled Set this to true to expose Central through a node port. The default value is false . central.exposure.nodeport.port Use this to specify an explicit node port. central.monitoring.exposeEndpoint Use Enabled to enable monitoring for Central. When you enable monitoring, RHACS creates a new monitoring service on port number 9090 . The default value is Disabled . central.nodeSelector If you want this component to only run on specific nodes, you can use this parameter to configure a node selector. central.resources.limits Use this parameter to override the default resource limits for the Central. central.resources.requests Use this parameter to override the default resource requests for the Central. central.imagePullSecrets Use this parameter to specify the image pull secrets for the Central image. central.db.passwordSecret.name Specify a secret that has the database password in the password data item. Only use this parameter if you want to specify a connection string manually. If omitted, the operator auto-generates a password and stores it in the password item in the central-db-password secret. central.db.connectionString Setting this parameter will not deploy Central DB, and Central will connect using the specified connection string. If you specify a value for this parameter, you must also specify a value for central.db.passwordSecret.name . This parameter has the following constraints: Connection string must be in keyword/value format as described in the PostgreSQL documentation. For more information, see the links in the Additional resources section. Only PostgreSQL 13 is supported. Connections through PGBouncer are not supported. User must be a superuser who can create and delete databases. central.db.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Central DB. This parameter is mainly used for infrastructure nodes. central.db.hostAliases Use this parameter to inject hosts and IP addresses into the pod's hosts file. central.db.persistence.hostPath.path Specify a host path to store persistent data in a directory on the host. Red Hat does not recommend using this. If you need to use host path, you must use it with a node selector. central.db.persistence.persistentVolumeClaim.claimName The name of the PVC to manage persistent data. If no PVC with the given name exists, it is created. The default value is central-db if not set. To prevent data loss, the PVC is not removed automatically when Central is deleted. central.db.persistence.persistentVolumeClaim.size The size of the persistent volume when created through the claim. This is automatically generated by default. central.db.persistence.persistentVolumeClaim.storageClassName The name of the storage class to use for the PVC. If your cluster is not configured with a default storage class, you must provide a value for this parameter. central.db.connectionPoolSize.minConnections Use this parameter to override the default minimum connection pool size between Central and Central DB. The default value is 10. central.db.connectionPoolSize.maxConnections Use this parameter to override the default maximum connection pool size between Central and Central DB. The default value is 90. Ensure that this value does not exceed the maximum number of connections supported by the Central DB: An Operator-managed Central DB supports a maximum of 200 connections by default.

Defaults to true on Red Hat OpenShift 4. network.policies To provide security at the network level, RHACS creates default NetworkPolicy resources in the namespace where Central is installed. These network policies allow ingress to specific components on specific ports. If you do not want RHACS to create these policies, set this parameter to Disabled . The default value is Enabled . Warning Disabling creation of default network policies can break communication between RHACS components. If you disable creation of default policies, you must create your own network policies to allow this communication. overlays See "Customizing the installation using the Operator with overlays". tls.additionalCAs Additional Trusted CA certificates for the secured cluster to trust. These certificates are typically used when integrating with services using a private certificate authority. 4.2.2. Customizing the installation using the Operator with overlays Learn how to tailor the installation of RHACS using the Operator method with overlays. 4.2.2.1. Overlays When Central or SecuredCluster custom resources don't expose certain low-level configuration options as parameters, you can use the .spec.overlays field for adjustments. Use this field to amend the Kubernetes resources generated by these custom resources. The .spec.overlays field comprises a sequence of patches, applied in their listed order. These patches are processed by the Operator on the Kubernetes resources before deployment to the cluster. Warning The .spec.overlays field in both Central and SecuredCluster allows users to modify low-level Kubernetes resources in arbitrary ways. Use this feature only when the desired customization is not available through the SecuredCluster or Central custom resources. Support for the .spec.overlays feature is limited primarily because it grants the ability to make intricate and highly specific modifications to Kubernetes resources, which can vary significantly from one implementation to another. This level of customization introduces a complexity that goes beyond standard usage scenarios, making it challenging to provide broad support. Each modification can be unique, potentially interacting with the Kubernetes system in unpredictable ways across different versions and configurations of the product. This variability means that troubleshooting and guaranteeing the stability of these customizations require a level of expertise and understanding specific to each individual's setup. Consequently, while this feature empowers tailoring Kubernetes resources to meet precise needs, greater responsibility must also assumed to ensure the compatibility and stability of configurations, especially during upgrades or changes to the underlying product. The following example shows the structure of an overlay: overlays: - apiVersion: v1 1 kind: ConfigMap 2 name: my-configmap 3 patches: - path: .data 4 value: | 5 key1: data2 key2: data2 1 Targeted Kubernetes resource ApiVersion, for example apps/v1 , v1 , networking.k8s.io/v1 2 Resource type (e.g., Deployment, ConfigMap, NetworkPolicy) 3 Name of the resource, for example my-configmap 4 JSONPath expression to the field, for example spec.template.spec.containers[name:central].env[-1] 5 YAML string for the new field value 4.2.2.1.1. Adding an overlay For customizations, you can add overlays to Central or SecuredCluster custom resources. Use the OpenShift CLI ( oc ) or the OpenShift Container Platform web console for modifications. If overlays do not take effect as expected, check the RHACS Operator logs for any syntax errors or issues logged. 4.2.2.2. Overlay examples 4.2.2.2.1. Specifying an EKS pod role ARN for the Central ServiceAccount Add an Amazon Elastic Kubernetes Service (EKS) pod role Amazon Resource Name (ARN) annotation to the central ServiceAccount as shown in the following example: apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: v1 kind: ServiceAccount name: central patches: - path: metadata.annotations.eks\.amazonaws\.com/role-arn value: "\"arn:aws:iam:1234:role\"" 4.2.2.2.2. Injecting an environment variable into the Central deployment Inject an environment variable into the central deployment as shown in the following example: apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: apps/v1 kind: Deployment name: central patches: - path: spec.template.spec.containers[name:central].env[-1] value: | name: MY_ENV_VAR value: value 4.2.2.2.3. Extending network policy with an ingress rule Add an ingress rule to the allow-ext-to-central network policy for port 999 traffic as shown in the following example: apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: networking.k8s.io/v1 kind: NetworkPolicy name: allow-ext-to-central patches: - path: spec.ingress[-1] value: | ports: - port: 999 protocol: TCP 4.2.2.2.4.

Generating and applying an init bundle for RHACS on Red Hat OpenShift Before you install the SecuredCluster resource on a cluster, you must create an init bundle. The cluster that has SecuredCluster installed and configured then uses this bundle to authenticate with Central. You can create an init bundle by using either the RHACS portal or the roxctl CLI. You then apply the init bundle by using it to create resources. To configure an init bundle for RHACS Cloud Service, see the following resources: Generating an init bundle for secured clusters (Red Hat Cloud) Applying an init bundle for secured clusters (Red Hat Cloud) Generating an init bundle for Kubernetes secured clusters Applying an init bundle for Kubernetes secured clusters Note You must have the Admin user role to create an init bundle. 4.3.1. Generating an init bundle 4.3.1.1. Generating an init bundle by using the RHACS portal You can create an init bundle containing secrets by using the RHACS portal. Note You must have the Admin user role to create an init bundle. Procedure Find the address of the RHACS portal as described in "Verifying Central installation using the Operator method". Log in to the RHACS portal. If you do not have secured clusters, the Platform Configuration Clusters page appears. Click Create init bundle . Enter a name for the cluster init bundle. Select your platform. Select the installation method you will use for your secured clusters: Operator or Helm chart . Click Download to generate and download the init bundle, which is created in the form of a YAML file. You can use one init bundle and its corresponding YAML file for all secured clusters if you are using the same installation method. Important Store this bundle securely because it contains secrets. Apply the init bundle by using it to create resources on the secured cluster. Install secured cluster services on each cluster. 4.3.1.2. Generating an init bundle by using the roxctl CLI You can create an init bundle with secrets by using the roxctl CLI. Note You must have the Admin user role to create init bundles. Prerequisites You have configured the ROX_API_TOKEN and the ROX_CENTRAL_ADDRESS environment variables: Set the ROX_API_TOKEN by running the following command: USD export ROX_API_TOKEN=<api_token> Set the ROX_CENTRAL_ADDRESS environment variable by running the following command: USD export ROX_CENTRAL_ADDRESS=<address>:<port_number> Procedure To generate a cluster init bundle containing secrets for Helm installations, run the following command: USD roxctl -e "USDROX_CENTRAL_ADDRESS" \ central init-bundles generate --output \ <cluster_init_bundle_name> cluster_init_bundle.yaml To generate a cluster init bundle containing secrets for Operator installations, run the following command: USD roxctl -e "USDROX_CENTRAL_ADDRESS" \ central init-bundles generate --output-secrets \ <cluster_init_bundle_name> cluster_init_bundle.yaml Important Ensure that you store this bundle securely because it contains secrets. You can use the same bundle to set up multiple secured clusters. 4.3.1.3. Applying the init bundle on the secured cluster Before you configure a secured cluster, you must apply the init bundle by using it to create the required resources on the cluster. Applying the init bundle allows the services on the secured cluster to communicate with Central. Note If you are installing by using Helm charts, do not perform this step. Complete the installation by using Helm; See "Installing RHACS on secured clusters by using Helm charts" in the additional resources section. Prerequisites You must have generated an init bundle containing secrets. You must have created the stackrox project, or namespace, on the cluster where secured cluster services will be installed. Using stackrox for the project is not required, but ensures that vulnerabilities for RHACS processes are not reported when scanning your clusters. Procedure To create resources, perform only one of the following steps: Create resources using the OpenShift Container Platform web console: In the OpenShift Container Platform web console, make sure that you are in the stackrox namespace. In the top menu, click + to open the Import YAML page. You can drag the init bundle file or copy and paste its contents into the editor, and then click Create . When the command is complete, the display shows that the collector-tls , sensor-tls , and admission-control-tls` resources were created. Create resources using the Red Hat OpenShift CLI: Using the Red Hat OpenShift CLI, run the following command to create the resources: USD oc create -f <init_bundle>.yaml \ 1 -n <stackrox> 2 1 Specify the file name of the init bundle containing the secrets. 2 Specify the name of the project where Central services are installed. 4.3.2. steps Install RHACS secured cluster services in all clusters that you want to monitor. 4.3.3. Additional resources Installing RHACS on secured clusters by using Helm charts 4.4. Installing Secured Cluster services for RHACS on Red Hat OpenShift You can install RHACS on your secured clusters by using one of the following methods: Install by using the Operator Install by using Helm charts Install by using the roxctl CLI (do not use this method unless you have a specific installation need that requires using it) 4.4.1. Installing RHACS on secured clusters by using the Operator 4.4.1.1. Installing secured cluster services You can install Secured Cluster services on your clusters by using the Operator, which creates the SecuredCluster custom resource. You must install the Secured Cluster services on every cluster in your environment that you want to monitor. Important When you install Red Hat Advanced Cluster Security for Kubernetes: If you are installing RHACS for the first time, you must first install the Central custom resource because the SecuredCluster custom resource installation is dependent on certificates that Central generates. Do not install SecuredCluster in projects whose names start with kube , openshift , or redhat , or in the istio-system project. If you are installing RHACS SecuredCluster custom resource on a cluster that also hosts Central, ensure that you install it in the same namespace as Central. If you are installing Red Hat Advanced Cluster Security for Kubernetes SecuredCluster custom resource on a cluster that does not host Central, Red Hat recommends that you install the Red Hat Advanced Cluster Security for Kubernetes SecuredCluster custom resource in its own project and not in the project in which you have installed the Red Hat Advanced Cluster Security for Kubernetes Operator. Prerequisites If you are using OpenShift Container Platform, you must install version 4.12 or later. You have installed the RHACS Operator on the cluster that you want to secure, called the secured cluster. You have generated an init bundle and applied it to the cluster. Procedure On the OpenShift Container Platform web console for the secured cluster, go to the Operators Installed Operators page. Click the RHACS Operator. If you have installed the Operator in the recommended namespace, OpenShift Container Platform lists the project as rhacs-operator . Select Project: rhacs-operator Create project . Note If you installed the Operator in a different namespace, OpenShift Container Platform lists the name of that namespace instead of rhacs-operator . Enter the new project name (for example, stackrox ), and click Create . Red Hat recommends that you use stackrox as the project name. Click Secured Cluster from the central navigation menu in the Operator details page. Click Create SecuredCluster . Select one of the following options in the Configure via field: Form view : Use this option if you want to use the on-screen fields to configure the secured cluster and do not need to change any other fields. YAML view : Use this view to set up the secured cluster by using the YAML file. The YAML file is displayed in the window and you can edit fields in it. If you select this option, when you are finished editing the file, click Create . If you are using Form view , enter the new project name by accepting or editing the default name. The default value is stackrox-secured-cluster-services . Optional: Add any labels for the cluster. Enter a unique name for your SecuredCluster custom resource. For Central Endpoint , enter the address of your Central instance. For example, if Central is available at https://central.example.com , then specify the central endpoint as central.example.com . Use the default value of central.stackrox.svc:443 only if you are installing secured cluster services in the same cluster where Central is installed. Do not use the default value when you are configuring multiple clusters. Instead, use the hostname when configuring the Central Endpoint value for each cluster. For the remaining fields, accept the default values or configure custom values if needed. For example, you might need to configure TLS if you are using custom certificates or untrusted CAs. See "Configuring Secured Cluster services options for RHACS using the Operator" for more information. Click Create . After a brief pause, the SecuredClusters page displays the status of stackrox-secured-cluster-services . You might see the following conditions: Conditions: Deployed, Initialized : The secured cluster services have been installed and the secured cluster is communicating with Central. Conditions: Initialized, Irreconcilable : The secured cluster is not communicating with Central. Make sure that you applied the init bundle you created in the RHACS web portal to the secured cluster. steps Configure additional secured cluster settings (optional). Verify installation. 4.4.2. Installing RHACS on secured clusters by using Helm charts You can install RHACS on secured clusters by using Helm charts with no customization, using the default values, or with customizations of configuration parameters. 4.4.2.1. Installing RHACS on secured clusters by using Helm charts without customizations 4.4.2.1.1. Adding the Helm chart repository Procedure Add the RHACS charts repository. USD helm repo add rhacs https://mirror.openshift.com/pub/rhacs/charts/ The Helm repository for Red Hat Advanced Cluster Security for Kubernetes includes Helm charts for installing different components, including: Central services Helm chart ( central-services ) for installing the centralized components (Central and Scanner). Note You deploy centralized components only once and you can monitor multiple separate clusters by using the same installation. Secured Cluster Services Helm chart ( secured-cluster-services ) for installing the per-cluster and per-node components (Sensor, Admission Controller, Collector, and Scanner-slim). Note Deploy the per-cluster components into each cluster that you want to monitor and deploy the per-node components in all nodes that you want to monitor. Verification Run the following command to verify the added chart repository: USD helm search repo -l rhacs/ 4.4.2.1.2. Installing the secured-cluster-services Helm chart without customization Use the following instructions to install the secured-cluster-services Helm chart to deploy the per-cluster and per-node components (Sensor, Admission controller, Collector, and Scanner-slim). Prerequisites You must have generated an RHACS init bundle for your cluster. You must have access to the Red Hat Container Registry and a pull secret for authentication. For information about downloading images from registry.redhat.io , see Red Hat Container Registry Authentication . You must have the address that you are exposing the Central service on. Procedure Run the following command on OpenShift Container Platform clusters: USD helm install -n stackrox --create-namespace \ stackrox-secured-cluster-services rhacs/secured-cluster-services \ -f <path_to_cluster_init_bundle.yaml> \ 1 -f <path_to_pull_secret.yaml> \ 2 --set clusterName=<name_of_the_secured_cluster> \ --set centralEndpoint=<endpoint_of_central_service> 3 --set scanner.disable=false 4 1 Use the -f option to specify the path for the init bundle. 2 Use the -f option to specify the path for the pull secret for Red Hat Container Registry authentication. 3 Specify the address and port number for Central. For example, acs.domain.com:443 . 4 Set the value of the scanner.disable parameter to false , which means that Scanner-slim will be enabled during the installation. In Kubernetes, the secured cluster services now include Scanner-slim as an optional component. Additional resources Generating and applying an init bundle for RHACS on Red Hat OpenShift 4.4.2.2. Configuring the secured-cluster-services Helm chart with customizations This section describes Helm chart configuration parameters that you can use with the helm install and helm upgrade commands. You can specify these parameters by using the --set option or by creating YAML configuration files. Create the following files for configuring the Helm chart for installing Red Hat Advanced Cluster Security for Kubernetes: Public configuration file values-public.yaml : Use this file to save all non-sensitive configuration options. Private configuration file values-private.yaml : Use this file to save all sensitive configuration options. Ensure that you store this file securely. Important While using the secured-cluster-services Helm chart, do not modify the values.yaml file that is part of the chart. 4.4.2.2.1. Configuration parameters Parameter Description clusterName Name of your cluster. centralEndpoint Address of the Central endpoint. If you are using a non-gRPC capable load balancer, use the WebSocket protocol by prefixing the endpoint address with wss:// . When configuring multiple clusters, use the hostname for the address. For example, central.example.com . sensor.endpoint Address of the Sensor endpoint including port number. sensor.imagePullPolicy Image pull policy for the Sensor container. sensor.serviceTLS.cert The internal service-to-service TLS certificate that Sensor uses. sensor.serviceTLS.key The internal service-to-service TLS certificate key that Sensor uses. sensor.resources.requests.memory The memory request for the Sensor container. Use this parameter to override the default value. sensor.resources.requests.cpu The CPU request for the Sensor container. Use this parameter to override the default value. sensor.resources.limits.memory The memory limit for the Sensor container. Use this parameter to override the default value. sensor.resources.limits.cpu The CPU limit for the Sensor container. Use this parameter to override the default value. sensor.nodeSelector Specify a node selector label as label-key: label-value to force Sensor to only schedule on nodes with the specified label. sensor.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Sensor. This parameter is mainly used for infrastructure nodes. image.main.name The name of the main image. image.collector.name The name of the Collector image. image.main.registry The address of the registry you are using for the main image. image.collector.registry The address of the registry you are using for the Collector image. image.scanner.registry The address of the registry you are using for the Scanner image. image.scannerDb.registry The address of the registry you are using for the Scanner DB image. image.scannerV4.registry The address of the registry you are using for the Scanner V4 image. image.scannerV4DB.registry The address of the registry you are using for the Scanner V4 DB image. image.main.pullPolicy Image pull policy for main images. image.collector.pullPolicy Image pull policy for the Collector images. image.main.tag Tag of main image to use. image.collector.tag Tag of collector image to use. collector.collectionMethod Either CORE_BPF or NO_COLLECTION . collector.imagePullPolicy Image pull policy for the Collector container. collector.complianceImagePullPolicy Image pull policy for the Compliance container. collector.disableTaintTolerations If you specify false , tolerations are applied to Collector, and the collector pods can schedule onto all nodes with taints. If you specify it as true , no tolerations are applied, and the collector pods are not scheduled onto nodes with taints. collector.resources.requests.memory The memory request for the Collector container. Use this parameter to override the default value. collector.resources.requests.cpu The CPU request for the Collector container. Use this parameter to override the default value. collector.resources.limits.memory The memory limit for the Collector container. Use this parameter to override the default value. collector.resources.limits.cpu The CPU limit for the Collector container.

Use this parameter to override the default value. collector.complianceResources.limits.memory The memory limit for the Compliance container. Use this parameter to override the default value. collector.complianceResources.limits.cpu The CPU limit for the Compliance container. Use this parameter to override the default value. collector.serviceTLS.cert The internal service-to-service TLS certificate that Collector uses. collector.serviceTLS.key The internal service-to-service TLS certificate key that Collector uses. admissionControl.listenOnCreates This setting controls whether Kubernetes is configured to contact Red Hat Advanced Cluster Security for Kubernetes with AdmissionReview requests for workload creation events. admissionControl.listenOnUpdates When you set this parameter as false , Red Hat Advanced Cluster Security for Kubernetes creates the ValidatingWebhookConfiguration in a way that causes the Kubernetes API server not to send object update events. Since the volume of object updates is usually higher than the object creates, leaving this as false limits the load on the admission control service and decreases the chances of a malfunctioning admission control service. admissionControl.listenOnEvents This setting controls whether the cluster is configured to contact Red Hat Advanced Cluster Security for Kubernetes with AdmissionReview requests for Kubernetes exec and portforward events. RHACS does not support this feature on OpenShift Container Platform 3.11. admissionControl.dynamic.enforceOnCreates This setting controls whether Red Hat Advanced Cluster Security for Kubernetes evaluates policies; if it is disabled, all AdmissionReview requests are automatically accepted. admissionControl.dynamic.enforceOnUpdates This setting controls the behavior of the admission control service. You must specify listenOnUpdates as true for this to work. admissionControl.dynamic.scanInline If you set this option to true , the admission control service requests an image scan before making an admission decision. Since image scans take several seconds, enable this option only if you can ensure that all images used in your cluster are scanned before deployment (for example, by a CI integration during image build). This option corresponds to the Contact image scanners option in the RHACS portal. admissionControl.dynamic.disableBypass Set it to true to disable bypassing the Admission controller. admissionControl.dynamic.timeout Use this parameter to specify the maximum number of seconds RHACS must wait for an admission review before marking it as fail open. If the admission webhook does not receive information that it is requesting before the end of the timeout period, it fails, but in fail open status, it still allows the operation to succeed. For example, the admission controller would allow a deployment to be created even if a scan had timed out and RHACS could not determine if the deployment violated a policy. Beginning in release 4.5, Red Hat reduced the default timeout setting for the RHACS admission controller webhooks from 20 seconds to 10 seconds, resulting in an effective timeout of 12 seconds within the ValidatingWebhookConfiguration . This change does not negatively affect OpenShift Container Platform users because OpenShift Container Platform caps the timeout at 13 seconds. admissionControl.resources.requests.memory The memory request for the Admission Control container. Use this parameter to override the default value. admissionControl.resources.requests.cpu The CPU request for the Admission Control container. Use this parameter to override the default value. admissionControl.resources.limits.memory The memory limit for the Admission Control container. Use this parameter to override the default value. admissionControl.resources.limits.cpu The CPU limit for the Admission Control container. Use this parameter to override the default value. admissionControl.nodeSelector Specify a node selector label as label-key: label-value to force Admission Control to only schedule on nodes with the specified label. admissionControl.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Admission Control. This parameter is mainly used for infrastructure nodes. admissionControl.serviceTLS.cert The internal service-to-service TLS certificate that Admission Control uses. admissionControl.serviceTLS.key The internal service-to-service TLS certificate key that Admission Control uses. registryOverride Use this parameter to override the default docker.io registry. Specify the name of your registry if you are using some other registry. collector.disableTaintTolerations If you specify false , tolerations are applied to Collector, and the Collector pods can schedule onto all nodes with taints. If you specify it as true , no tolerations are applied, and the Collector pods are not scheduled onto nodes with taints. createUpgraderServiceAccount Specify true to create the sensor-upgrader account. By default, Red Hat Advanced Cluster Security for Kubernetes creates a service account called sensor-upgrader in each secured cluster. This account is highly privileged but is only used during upgrades. If you do not create this account, you must complete future upgrades manually if the Sensor does not have enough permissions. createSecrets Specify false to skip the orchestrator secret creation for the Sensor, Collector, and Admission controller. collector.slimMode Deprecated. Specify true if you want to use a slim Collector image for deploying Collector. sensor.resources Resource specification for Sensor. admissionControl.resources Resource specification for Admission controller. collector.resources Resource specification for Collector. collector.complianceResources Resource specification for Collector's Compliance container. exposeMonitoring If you set this option to true , Red Hat Advanced Cluster Security for Kubernetes exposes Prometheus metrics endpoints on port number 9090 for the Sensor, Collector, and the Admission controller. auditLogs.disableCollection If you set this option to true , Red Hat Advanced Cluster Security for Kubernetes disables the audit log detection features used to detect access and modifications to configuration maps and secrets. scanner.disable If you set this option to false , Red Hat Advanced Cluster Security for Kubernetes deploys a Scanner-slim and Scanner DB in the secured cluster to allow scanning images on the integrated OpenShift image registry. Enabling Scanner-slim is supported on OpenShift Container Platform and Kubernetes secured clusters. Defaults to true . scanner.dbTolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Scanner DB. scanner.replicas Resource specification for Collector's Compliance container. scanner.logLevel Setting this parameter allows you to modify the scanner log level. Use this option only for troubleshooting purposes. scanner.autoscaling.disable If you set this option to true , Red Hat Advanced Cluster Security for Kubernetes disables autoscaling on the Scanner deployment. scanner.autoscaling.minReplicas The minimum number of replicas for autoscaling. Defaults to 2. scanner.autoscaling.maxReplicas The maximum number of replicas for autoscaling. Defaults to 5. scanner.nodeSelector Specify a node selector label as label-key: label-value to force Scanner to only schedule on nodes with the specified label. scanner.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Scanner. scanner.dbNodeSelector Specify a node selector label as label-key: label-value to force Scanner DB to only schedule on nodes with the specified label. scanner.dbTolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Scanner DB. scanner.resources.requests.memory The memory request for the Scanner container. Use this parameter to override the default value. scanner.resources.requests.cpu The CPU request for the Scanner container. Use this parameter to override the default value. scanner.resources.limits.memory The memory limit for the Scanner container. Use this parameter to override the default value. scanner.resources.limits.cpu The CPU limit for the Scanner container. Use this parameter to override the default value. scanner.dbResources.requests.memory The memory request for the Scanner DB container. Use this parameter to override the default value. scanner.dbResources.requests.cpu The CPU request for the Scanner DB container. Use this parameter to override the default value. scanner.dbResources.limits.memory The memory limit for the Scanner DB container. Use this parameter to override the default value. scanner.dbResources.limits.cpu The CPU limit for the Scanner DB container. Use this parameter to override the default value. monitoring.openshift.enabled If you set this option to false , Red Hat Advanced Cluster Security for Kubernetes will not set up Red Hat OpenShift monitoring. Defaults to true on Red Hat OpenShift 4. network.enableNetworkPolicies To provide security at the network level, RHACS creates default NetworkPolicy resources in the namespace where secured cluster resources are installed. These network policies allow ingress to specific components on specific ports. If you do not want RHACS to create these policies, set this parameter to False . This is a Boolean value. The default value is True , which means the default policies are automatically created. Warning Disabling creation of default network policies can break communication between RHACS components. If you disable creation of default policies, you must create your own network policies to allow this communication. 4.4.2.2.1.1. Environment variables You can specify environment variables for Sensor and Admission controller in the following format: customize: envVars: ENV_VAR1: "value1" ENV_VAR2: "value2" The customize setting allows you to specify custom Kubernetes metadata (labels and annotations) for all objects created by this Helm chart and additional pod labels, pod annotations, and container environment variables for workloads. The configuration is hierarchical, in the sense that metadata defined at a more generic scope (for example, for all objects) can be overridden by metadata defined at a narrower scope (for example, only for the Sensor deployment). 4.4.2.2.2. Installing the secured-cluster-services Helm chart with customizations After you configure the values-public.yaml and values-private.yaml files, install the secured-cluster-services Helm chart to deploy the following per-cluster and per-node components: Sensor Admission controller Collector Scanner: optional for secured clusters when the StackRox Scanner is installed Scanner DB: optional for secured clusters when the StackRox Scanner is installed Scanner V4 Indexer and Scanner V4 DB: optional for secured clusters when Scanner V4 is installed Prerequisites You must have generated an RHACS init bundle for your cluster. You must have access to the Red Hat Container Registry and a pull secret for authentication. For information about downloading images from registry.redhat.io , see Red Hat Container Registry Authentication . You must have the address and the port number that you are exposing the Central service on. Procedure Run the following command: USD helm install -n stackrox \ --create-namespace stackrox-secured-cluster-services rhacs/secured-cluster-services \ -f <name_of_cluster_init_bundle.yaml> \ -f <path_to_values_public.yaml> -f <path_to_values_private.yaml> \ 1 --set imagePullSecrets.username=<username> \ 2 --set imagePullSecrets.password=<password> 3 1 Use the -f option to specify the paths for your YAML configuration files. 2 Include the user name for your pull secret for Red Hat Container Registry authentication. 3 Include the password for your pull secret for Red Hat Container Registry authentication. Note To deploy secured-cluster-services Helm chart by using a continuous integration (CI) system, pass the init bundle YAML file as an environment variable to the helm install command: USD helm install ... -f <(echo "USDINIT_BUNDLE_YAML_SECRET") 1 1 If you are using base64 encoded variables, use the helm install ... -f <(echo "USDINIT_BUNDLE_YAML_SECRET" | base64 --decode) command instead. Additional resources Generating and applying an init bundle for RHACS on Red Hat OpenShift 4.4.2.3. Changing configuration options after deploying the secured-cluster-services Helm chart You can make changes to any configuration options after you have deployed the secured-cluster-services Helm chart. When using the helm upgrade command to make changes, the following guidelines and requirements apply: You can also specify configuration values using the --set or --set-file parameters. However, these options are not saved, and you must manually specify all the options again whenever you make changes. Some changes, such as enabling a new component like Scanner V4, require new certificates to be issued for the component. Therefore, you must provide a CA when making these changes. If the CA was generated by the Helm chart during the initial installation, you must retrieve these automatically generated values from the cluster and provide them to the helm upgrade command. The post-installation notes of the central-services Helm chart include a command for retrieving the automatically generated values. If the CA was generated outside of the Helm chart and provided during the installation of the central-services chart, then you must perform that action again when using the helm upgrade command, for example, by using the --reuse-values flag with the helm upgrade command. Procedure Update the values-public.yaml and values-private.yaml configuration files with new values. Run the helm upgrade command and specify the configuration files using the -f option: USD helm upgrade -n stackrox \ stackrox-secured-cluster-services rhacs/secured-cluster-services \ --reuse-values \ 1 -f <path_to_values_public.yaml> \ -f <path_to_values_private.yaml> 1 If you have modified values that are not included in the values_public.yaml and values_private.yaml files, include the --reuse-values parameter. 4.4.3. Installing RHACS on secured clusters by using the roxctl CLI This method is also referred to as the manifest installation method. Prerequisites If you plan to use the roxctl CLI command to generate the files used by the sensor installation script, you have installed the roxctl CLI. You have generated the files that will be used by the sensor installation script. Procedure On the OpenShift Container Platform secured cluster, deploy the Sensor component by running the sensor installation script. 4.4.3.1. Installing the roxctl CLI You must first download the binary. You can install roxctl on Linux, Windows, or macOS. 4.4.3.1.1. Installing the roxctl CLI on Linux You can install the roxctl CLI binary on Linux by using the following procedure. Note roxctl CLI for Linux is available for amd64 , arm64 , ppc64le , and s390x architectures. Procedure Determine the roxctl architecture for the target operating system: USD arch="USD(uname -m | sed "s/x86_64//")"; arch="USD{arch:+-USDarch}" Download the roxctl CLI: USD curl -L -f -o roxctl "https://mirror.openshift.com/pub/rhacs/assets/4.6.3/bin/Linux/roxctlUSD{arch}" Make the roxctl binary executable: USD chmod +x roxctl Place the roxctl binary in a directory that is on your PATH : To check your PATH , execute the following command: USD echo USDPATH Verification Verify the roxctl version you have installed: USD roxctl version 4.4.3.1.2. Installing the roxctl CLI on macOS You can install the roxctl CLI binary on macOS by using the following procedure. Note roxctl CLI for macOS is available for amd64 and arm64 architectures. Procedure Determine the roxctl architecture for the target operating system: USD arch="USD(uname -m | sed "s/x86_64//")"; arch="USD{arch:+-USDarch}" Download the roxctl CLI: USD curl -L -f -o roxctl "https://mirror.openshift.com/pub/rhacs/assets/4.6.3/bin/Darwin/roxctlUSD{arch}" Remove all extended attributes from the binary: USD xattr -c roxctl Make the roxctl binary executable: USD chmod +x roxctl Place the roxctl binary in a directory that is on your PATH : To check your PATH , execute the following command: USD echo USDPATH Verification Verify the roxctl version you have installed: USD roxctl version 4.4.3.1.3. Installing the roxctl CLI on Windows You can install the roxctl CLI binary on Windows by using the following procedure. Note roxctl CLI for Windows is available for the amd64 architecture. Procedure Download the roxctl CLI: USD curl -f -O https://mirror.openshift.com/pub/rhacs/assets/4.6.3/bin/Windows/roxctl.exe Verification Verify the roxctl version you have installed: USD roxctl version 4.4.3.2. Installing Sensor To monitor a cluster, you must deploy Sensor. You must deploy Sensor into each cluster that you want to monitor. This installation method is also called the manifest installation method. To perform an installation by using the manifest installation method, follow only one of the following procedures: Use the RHACS web portal to download the cluster bundle, and then extract and run the sensor script. Use the roxctl CLI to generate the required sensor configuration for your OpenShift Container Platform cluster and associate it with your Central instance. Prerequisites You must have already installed Central services, or you can access Central services by selecting your ACS instance on Red Hat Advanced Cluster Security Cloud Service (RHACS Cloud Service). 4.4.3.2.1. Manifest installation method by using the web portal Procedure On your secured cluster, in the RHACS portal, go to Platform Configuration Clusters . Select Secure a cluster Legacy installation method . Specify a name for the cluster. Provide appropriate values for the fields based on where you are deploying the Sensor. If you are deploying Sensor in the same cluster, accept the default values for all the fields. If you are deploying into a different cluster, replace central.stackrox.svc:443 with a load balancer, node port, or other address, including the port number, that is accessible from the other cluster. If you are using a non-gRPC capable load balancer, such as HAProxy, AWS Application Load Balancer (ALB), or AWS Elastic Load Balancing (ELB), use the WebSocket Secure ( wss ) protocol. To use wss : Prefix the address with wss:// . Add the port number after the address, for example, wss://stackrox-central.example.com:443 . Click to continue with the Sensor setup. Click Download YAML File and Keys to download the cluster bundle (zip archive). Important The cluster bundle zip archive includes unique configurations and keys for each cluster. Do not reuse the same files in another cluster. From a system that has access to the monitored cluster, extract and run the sensor script from the cluster bundle: USD unzip -d sensor sensor-<cluster_name>.zip USD ./sensor/sensor.sh If you get a warning that you do not have the required permissions to deploy Sensor, follow the on-screen instructions, or contact your cluster administrator for help. After Sensor is deployed, it contacts Central and provides cluster information. 4.4.3.2.2. Manifest installation by using the roxctl CLI Procedure Generate the required sensor configuration for your OpenShift Container Platform cluster and associate it with your Central instance by running the following command: USD roxctl sensor generate openshift --openshift-version <ocp_version> --name <cluster_name> --central "USDROX_ENDPOINT" 1 1 For the --openshift-version option, specify the major OpenShift Container Platform version number for your cluster. For example, specify 3 for OpenShift Container Platform version 3.x and specify 4 for OpenShift Container Platform version 4.x . From a system that has access to the monitored cluster, extract and run the sensor script from the cluster bundle: USD unzip -d sensor sensor-<cluster_name>.zip USD ./sensor/sensor.sh If you get a warning that you do not have the required permissions to deploy Sensor, follow the on-screen instructions, or contact your cluster administrator for help. After Sensor is deployed, it contacts Central and provides cluster information. Verification Return to the RHACS portal and check if the deployment is successful. If successful, when viewing your list of clusters in Platform Configuration Clusters , the cluster status displays a green checkmark and a Healthy status. If you do not see a green checkmark, use the following command to check for problems: On OpenShift Container Platform, enter the following command: USD oc get pod -n stackrox -w On Kubernetes, enter the following command: USD kubectl get pod -n stackrox -w Click Finish to close the window. After installation, Sensor starts reporting security information to RHACS and the RHACS portal dashboard begins showing deployments, images, and policy violations from the cluster on which you have installed the Sensor. 4.5. Configuring Secured Cluster services options for RHACS using the Operator When installing Secured Cluster services by using the Operator, you can configure optional settings. 4.5.1. Secured Cluster services configuration options When you create a Central instance, the Operator lists the following configuration options for the Central custom resource. 4.5.1.1. Required Configuration Settings Parameter Description centralEndpoint The endpoint of Central instance to connect to, including the port number. If using a non-gRPC capable load balancer, use the WebSocket protocol by prefixing the endpoint address with wss:// . If you do not specify a value for this parameter, Sensor attempts to connect to a Central instance running in the same namespace. clusterName The unique name of this cluster, which shows up in the RHACS portal. After you set the name by using this parameter, you cannot change it again. To change the name, you must delete and re-create the object. 4.5.1.2. Admission controller settings Parameter Description admissionControl.listenOnCreates Specify true to enable preventive policy enforcement for object creations. The default value is true . admissionControl.listenOnEvents Specify true to enable monitoring and enforcement for Kubernetes events, such as port-forward and exec events. It is used to control access to resources through the Kubernetes API. The default value is true . admissionControl.listenOnUpdates Specify true to enable preventive policy enforcement for object updates. It will not have any effect unless Listen On Creates is set to true as well. The default value is true . admissionControl.nodeSelector If you want this component to only run on specific nodes, you can configure a node selector using this parameter. admissionControl.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Admission Control. This parameter is mainly used for infrastructure nodes. admissionControl.hostAliases Use this parameter to inject hosts and IP addresses into the pod's hosts file. admissionControl.resources.limits Use this parameter to override the default resource limits for the admission controller. admissionControl.resources.requests Use this parameter to override the default resource requests for the admission controller. admissionControl.bypass Use one of the following values to configure the bypassing of admission controller enforcement: BreakGlassAnnotation to enable bypassing the admission controller via the admission.stackrox.io/break-glass annotation. Disabled to disable the ability to bypass admission controller enforcement for the secured cluster. The default value is BreakGlassAnnotation . admissionControl.contactImageScanners Use one of the following values to specify if the admission controller must connect to the image scanner: ScanIfMissing if the scan results for the image are missing. DoNotScanInline to skip scanning the image when processing the admission request. The default value is DoNotScanInline . admissionControl.timeoutSeconds Use this parameter to specify the maximum number of seconds RHACS must wait for an admission review before marking it as fail open. If the admission webhook does not receive information that it is requesting before the end of the timeout period, it fails, but in fail open status, it still allows the operation to succeed. For example, the admission controller would allow a deployment to be created even if a scan had timed out and RHACS could not determine if the deployment violated a policy. Beginning in release 4.5, Red Hat reduced the default timeout setting for the RHACS admission controller webhooks from 20 seconds to 10 seconds, resulting in an effective timeout of 12 seconds within the ValidatingWebhookConfiguration . This change does not negatively affect OpenShift Container Platform users because OpenShift Container Platform caps the timeout at 13 seconds. 4.5.1.3. Scanner configuration Use Scanner configuration settings to modify the local cluster scanner for the integrated OpenShift image registry. Parameter Description scanner.analyzer.nodeSelector Specify a node selector label as label-key: label-value to force Scanner to only schedule on nodes with the specified label. scanner.analyzer.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Scanner. scanner.analyzer.hostAliases Use this parameter to inject hosts and IP addresses into the pod's hosts file. scanner.analyzer.resources.requests.memory The memory request for the Scanner container.

This parameter is mainly used for infrastructure nodes. scannerV4.db.resources.limits Use this parameter to override the default resource limits for Scanner V4 DB. scannerV4.db.resources.requests Use this parameter to override the default resource requests for Scanner V4 DB. scannerV4.db.persistence.persistentVolumeClaim.claimName The name of the PVC to manage persistent data for Scanner V4. If no PVC with the given name exists, it is created. The default value is scanner-v4-db if not set. To prevent data loss, the PVC is not removed automatically when Central is deleted. scannerV4.db.persistence.persistentVolumeClaim.size The size of the PVC to manage persistent data for Scanner V4. scannerV4.db.persistence.persistentVolumeClaim.storageClassName The name of the storage class to use for the PVC. If your cluster is not configured with a default storage class, you must provide a value for this parameter. scannerV4.indexer.nodeSelector If you want this component to only run on specific nodes, you can use this parameter to configure a node selector. scannerV4.indexer.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for the Scanner V4 Indexer. This parameter is mainly used for infrastructure nodes. scannerV4.indexer.resources.limits Use this parameter to override the default resource limits for the Scanner V4 Indexer. scannerV4.indexer.resources.requests Use this parameter to override the default resource requests for the Scanner V4 Indexer. scannerV4.indexer.scaling.autoScaling When enabled, the number of Scanner V4 Indexer replicas is managed dynamically based on the load, within the limits specified. scannerV4.indexer.scaling.maxReplicas Specifies the maximum replicas to be used in the Scanner V4 Indexer autoscaling configuration. scannerV4.indexer.scaling.minReplicas Specifies the minimum replicas to be used in the Scanner V4 Indexer autoscaling configuration. scannerV4.indexer.scaling.replicas When autoscaling is disabled for the Scanner V4 Indexer, the number of replicas is always configured to match this value. scannerV4.monitoring.exposeEndpoint Configures a monitoring endpoint for Scanner V4. The monitoring endpoint allows other services to collect metrics from Scanner V4, provided in a Prometheus-compatible format. Use Enabled to expose the monitoring endpoint. When you enable monitoring, RHACS creates a new service, monitoring , with port 9090, and a network policy allowing inbound connections to the port. By default, this is not enabled. scannerV4.scannerComponent Enables Scanner V4. Valid values are: * Default : Scanner V4 is not enabled and not deployed. * AutoSense : If Central exists in the same namespace, Scanner V4 is not deployed and the existing Scanner V4 that was installed with Central is used. If there is no Central in this namespace, Scanner V4 is deployed. * Disabled : Do not deploy Scanner V4. 4.5.1.4. Image configuration Use image configuration settings when you are using a custom registry. Parameter Description imagePullSecrets.name Additional image pull secrets to be taken into account for pulling images. 4.5.1.5. Per node settings Per node settings define the configuration settings for components that run on each node in a cluster to secure the cluster. These components are Collector and Compliance. Parameter Description perNode.collector.collection The method for system-level data collection. The default value is CORE_BPF . Red Hat recommends using CORE_BPF for data collection. If you select NoCollection , Collector does not report any information about the network activity and the process executions. Available options are NoCollection and CORE_BPF . The EBPF option is available only for version 4.4 and earlier. perNode.collector.imageFlavor The image type to use for Collector. You can specify it as Regular or Slim . This value is deprecated.

Sensor configuration This configuration defines the settings of the Sensor components, which runs on one node in a cluster. Parameter Description sensor.nodeSelector If you want Sensor to only run on specific nodes, you can configure a node selector. sensor.tolerations If the node selector selects tainted nodes, use this parameter to specify a taint toleration key, value, and effect for Sensor. This parameter is mainly used for infrastructure nodes. sensor.hostAliases Use this parameter to inject hosts and IP addresses into the pod's hosts file. sensor.resources.limits Use this parameter to override the default resource limits for Sensor. sensor.resources.requests Use this parameter to override the default resource requests for Sensor. 4.5.1.7. General and miscellaneous settings Parameter Description customize.annotations Allows specifying custom annotations for the Central deployment. customize.envVars Advanced settings to configure environment variables. egress.connectivityPolicy Configures whether Red Hat Advanced Cluster Security for Kubernetes should run in online or offline mode. In offline mode, automatic updates of vulnerability definitions and kernel modules are disabled. misc.createSCCs Set this to true to create SCCs for Central. It may cause issues in some environments. network.policies To provide security at the network level, RHACS creates default NetworkPolicy resources in the namespace where secured cluster resources are installed. These network policies allow ingress to specific components on specific ports. If you do not want RHACS to create these policies, set this parameter to Disabled . The default value is Enabled . Warning Disabling creation of default network policies can break communication between RHACS components. If you disable creation of default policies, you must create your own network policies to allow this communication. overlays See "Customizing the installation using the Operator with overlays". tls.additionalCAs Additional trusted CA certificates for the secured cluster. These certificates are used when integrating with services using a private certificate authority. 4.5.2. Customizing the installation using the Operator with overlays Learn how to tailor the installation of RHACS using the Operator method with overlays. 4.5.2.1. Overlays When Central or SecuredCluster custom resources don't expose certain low-level configuration options as parameters, you can use the .spec.overlays field for adjustments. Use this field to amend the Kubernetes resources generated by these custom resources. The .spec.overlays field comprises a sequence of patches, applied in their listed order. These patches are processed by the Operator on the Kubernetes resources before deployment to the cluster. Warning The .spec.overlays field in both Central and SecuredCluster allows users to modify low-level Kubernetes resources in arbitrary ways. Use this feature only when the desired customization is not available through the SecuredCluster or Central custom resources. Support for the .spec.overlays feature is limited primarily because it grants the ability to make intricate and highly specific modifications to Kubernetes resources, which can vary significantly from one implementation to another. This level of customization introduces a complexity that goes beyond standard usage scenarios, making it challenging to provide broad support. Each modification can be unique, potentially interacting with the Kubernetes system in unpredictable ways across different versions and configurations of the product. This variability means that troubleshooting and guaranteeing the stability of these customizations require a level of expertise and understanding specific to each individual's setup. Consequently, while this feature empowers tailoring Kubernetes resources to meet precise needs, greater responsibility must also assumed to ensure the compatibility and stability of configurations, especially during upgrades or changes to the underlying product. The following example shows the structure of an overlay: overlays: - apiVersion: v1 1 kind: ConfigMap 2 name: my-configmap 3 patches: - path: .data 4 value: | 5 key1: data2 key2: data2 1 Targeted Kubernetes resource ApiVersion, for example apps/v1 , v1 , networking.k8s.io/v1 2 Resource type (e.g., Deployment, ConfigMap, NetworkPolicy) 3 Name of the resource, for example my-configmap 4 JSONPath expression to the field, for example spec.template.spec.containers[name:central].env[-1] 5 YAML string for the new field value 4.5.2.1.1. Adding an overlay For customizations, you can add overlays to Central or SecuredCluster custom resources. Use the OpenShift CLI ( oc ) or the OpenShift Container Platform web console for modifications. If overlays do not take effect as expected, check the RHACS Operator logs for any syntax errors or issues logged. 4.5.2.2. Overlay examples 4.5.2.2.1. Specifying an EKS pod role ARN for the Central ServiceAccount Add an Amazon Elastic Kubernetes Service (EKS) pod role Amazon Resource Name (ARN) annotation to the central ServiceAccount as shown in the following example: apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: v1 kind: ServiceAccount name: central patches: - path: metadata.annotations.eks\.amazonaws\.com/role-arn value: "\"arn:aws:iam:1234:role\"" 4.5.2.2.2. Injecting an environment variable into the Central deployment Inject an environment variable into the central deployment as shown in the following example: apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: apps/v1 kind: Deployment name: central patches: - path: spec.template.spec.containers[name:central].env[-1] value: | name: MY_ENV_VAR value: value 4.5.2.2.3. Extending network policy with an ingress rule Add an ingress rule to the allow-ext-to-central network policy for port 999 traffic as shown in the following example: apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: networking.k8s.io/v1 kind: NetworkPolicy name: allow-ext-to-central patches: - path: spec.ingress[-1] value: | ports: - port: 999 protocol: TCP 4.5.2.2.4. Modifying ConfigMap data Modify the central-endpoints ConfigMap data as shown in the following example: apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: v1 kind: ConfigMap name: central-endpoints patches: - path: data value: | endpoints.yaml: | disableDefault: false 4.5.2.2.5. Adding a container to the Central deployment Add a new container to the central deployment as shown in the following example:. apiVersion: platform.stackrox.io kind: Central metadata: name: central spec: # ... overlays: - apiVersion: apps/v1 kind: Deployment name: central patches: - path: spec.template.spec.containers[-1] value: | name: nginx image: nginx ports: - containerPort: 8000 name: http protocol: TCP 4.6. Verifying installation of RHACS on Red Hat OpenShift Provides steps to verify that RHACS is properly installed. 4.6.1. Verifying installation After you complete the installation, run a few vulnerable applications and go to the RHACS portal to evaluate the results of security assessments and policy violations. Note The sample applications listed in the following section contain critical vulnerabilities and they are specifically designed to verify the build and deploy-time assessment features of Red Hat Advanced Cluster Security for Kubernetes. To verify installation: Find the address of the RHACS portal based on your exposure method: For a route: USD oc get route central -n stackrox For a load balancer: USD oc get service central-loadbalancer -n stackrox For port forward: Run the following command: USD oc port-forward svc/central 18443:443 -n stackrox Go to https://localhost:18443/ . Using the Red Hat OpenShift CLI, create a new project: USD oc new-project test Start some applications with critical vulnerabilities: USD oc run shell --labels=app=shellshock,team=test-team \ --image=quay.io/stackrox-io/docs:example-vulnerables-cve-2014-6271 -n test USD oc run samba --labels=app=rce \ --image=quay.io/stackrox-io/docs:example-vulnerables-cve-2017-7494 -n test Red Hat Advanced Cluster Security for Kubernetes automatically scans these deployments for security risks and policy violations as soon as they are submitted to the cluster. Go to the RHACS portal to view the violations. You can log in to the RHACS portal by using the default username admin and the generated password.
