Chapter 5. Installing RHACS on other platforms 5.1. High-level overview of installing RHACS on other platforms Red Hat Advanced Cluster Security for Kubernetes (RHACS) provides security services for self-managed RHACS on platforms such as Amazon Elastic Kubernetes Service (Amazon EKS), Google Kubernetes Engine (Google GKE), and Microsoft Azure Kubernetes Service (Microsoft AKS). Before you install: Understand the installation methods for different platforms . Understand Red Hat Advanced Cluster Security for Kubernetes architecture . Check the default resource requirements page . The following list provides a high-level overview of installation steps: Install Central services on a cluster using Helm charts or the roxctl CLI. Generate and apply an init bundle . Install secured cluster resources on each of your secured clusters. 5.2. Installing Central services for RHACS on other platforms 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 by using one of the following methods: 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) 5.2.1. 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. 5.2.1.1. Install Central using Helm charts without customization You can install RHACS on your Red Hat OpenShift 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. 5.2.1.1.1. 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/ 5.2.1.1.2. 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. 5.2.1.2. 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. 5.2.1.2.1. Private configuration file This section lists the configurable parameters of the values-private.yaml file. There are no default values for these parameters. 5.2.1.2.1.1. 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.

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. 5.2.1.3. 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. 5.2.2. 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. 5.2.2.1. 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. 5.2.2.1.1. Installing the roxctl CLI on Linux You can install the roxctl CLI binary on Linux by using the following procedure.

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/4.5.6/bin/Windows/roxctl.exe Verification Verify the roxctl version you have installed: USD roxctl version 5.2.2.2. 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: Enter path to the backup bundle from which to restore keys and certificates (optional): Enter read templates from local filesystem (default: "false"): Enter path to helm templates on your local filesystem (default: "/path"): Enter PEM cert bundle file (optional): 1 Enter Create PodSecurityPolicy resources (for pre-v1.25 Kubernetes) (default: "true"): 2 Enter administrator password (default: autogenerated): Enter orchestrator (k8s, openshift): Enter default container images settings (development_build, stackrox.io, rhacs, opensource); it controls repositories from where to download the images, image names and tags format (default: "development_build"): Enter the directory to output the deployment bundle to (default: "central-bundle"): Enter the OpenShift major version (3 or 4) to deploy on (default: "0"): Enter whether to enable telemetry (default: "false"): Enter central-db image to use (if unset, a default will be used according to --image-defaults): Enter Istio version when deploying into an Istio-enabled cluster (leave empty when not running Istio) (optional): Enter the method of exposing Central (route, lb, np, none) (default: "none"): 3 Enter main image to use (if unset, a default will be used according to --image-defaults): Enter whether to run StackRox in offline mode, which avoids reaching out to the Internet (default: "false"): Enter list of secrets to add as declarative configuration mounts in central (default: "[]"): 4 Enter list of config maps to add as declarative configuration mounts in central (default: "[]"): 5 Enter the deployment tool to use (kubectl, helm, helm-values) (default: "kubectl"): Enter scanner-db image to use (if unset, a default will be used according to --image-defaults): Enter scanner image to use (if unset, a default will be used according to --image-defaults): Enter Central volume type (hostpath, pvc): 6 Enter external volume name for Central (default: "stackrox-db"): Enter external volume size in Gi for Central (default: "100"): Enter storage class name for Central (optional if you have a default StorageClass configured): Enter external volume name for Central DB (default: "central-db"): Enter external volume size in Gi for Central DB (default: "100"): Enter storage class name for Central DB (optional if you have a default StorageClass configured): 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 To use the RHACS portal, you must expose Central by using a route, a load balancer or a node port. 4 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". 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". 6 If you plan to install Red Hat Advanced Cluster Security for Kubernetes on OpenShift Container Platform with a hostPath volume, you must modify the SELinux policy. 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. 5.2.2.3. 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 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 5.3. Generating and applying an init bundle for RHACS on other platforms 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. Note You must have the Admin user role to create an init bundle. 5.3.1. Generating an init bundle 5.3.1.1. 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. 5.3.1.2. 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. 5.3.1.3. 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. Using the kubectl CLI, run the following commands to create the resources: USD kubectl create namespace stackrox 1 USD kubectl create -f <init_bundle>.yaml \ 2 -n <stackrox> 3 1 Create the project where secured cluster resources will be installed. This example uses stackrox . 2 Specify the file name of the init bundle containing the secrets. 3 Specify the project name that you created. This example uses stackrox . 5.3.2. steps Install RHACS secured cluster services in all clusters that you want to monitor. 5.4. Installing Secured Cluster services for RHACS on other platforms You can install RHACS on your secured clusters for platforms such as Amazon Elastic Kubernetes Service (Amazon EKS), Google Kubernetes Engine (Google GKE), and Microsoft Azure Kubernetes Service (Microsoft AKS). 5.4.1. 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. 5.4.1.1. Installing RHACS on secured clusters by using Helm charts without customizations 5.4.1.1.1. 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/ 5.4.1.1.2. 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. Additional resources Generating and applying an init bundle for RHACS on other platforms 5.4.1.2. 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. 5.4.1.2.1. 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.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 . 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. 5.4.1.2.1.1. 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). 5.4.1.2.2. 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 other platforms 5.4.1.3. 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.

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/4.5.6/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 5.4.2.1.2. 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/4.5.6/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 5.4.2.1.3. 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/4.5.6/bin/Windows/roxctl.exe Verification Verify the roxctl version you have installed: USD roxctl version 5.4.2.2. 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). 5.4.2.2.1. 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. 5.4.2.2.2. 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 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. 5.5. Verifying installation of RHACS on other platforms Provides steps to verify that RHACS is properly installed. 5.5.1. 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 load balancer: USD kubectl get service central-loadbalancer -n stackrox For port forward: Run the following command: USD kubectl port-forward svc/central 18443:443 -n stackrox Go to https://localhost:18443/ . Create a new namespace: USD kubectl create namespace test Start some applications with critical vulnerabilities: USD kubectl run shell --labels=app=shellshock,team=test-team \ --image=quay.io/stackrox-io/docs:example-vulnerables-cve-2014-6271 -n test USD kubectl 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.
