Chapter 4. Advanced Concepts These cover additional configuration topics, such as seting up keystores and a truststore for the Red Hat Single Sign-On server, creating an administrator account, an overview of available Red Hat Single Sign-On client registration methods, and guidance on configuring clustering. 4.1. Requirements and Deploying Passthrough TLS Termination Red Hat Single Sign-On Templates 4.1.1. Preparing the Deployment Log in to the OpenShift CLI with a user that holds the cluster:admin role. Create a new project: USD oc new-project sso-app-demo Add the view role to the default service account. This enables the service account to view all the resources in the sso-app-demo namespace, which is necessary for managing the cluster. USD oc policy add-role-to-user view system:serviceaccount:USD(oc project -q):default 4.1.2. Creating HTTPS and JGroups Keystores, and Truststore for the Red Hat Single Sign-On Server The Red Hat Single Sign-On application templates using passthrough TLS termination require: An HTTPS keystore used for encryption of https traffic, The JGroups keystore used for encryption of JGroups communications between nodes in the cluster, and Red Hat Single Sign-On server truststore used for securing the Red Hat Single Sign-On requests the Red Hat Single Sign-On for OpenShift image to be deployed properly. Important The Red Hat Single Sign-On application templates using re-encryption TLS termination do not require or expect the aforementioned HTTPS and JGroups keystores and Red Hat Single Sign-On server truststore to be prepared beforehand. The templates use OpenShift's internal service serving x509 certificate secrets to automatically create the HTTPS and JGroups keystores. The Red Hat Single Sign-On server truststore is also created automatically, containing the /var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt CA certificate file, which is used to create these cluster certificates. Moreover, the truststore for the Red Hat Single Sign-On server is pre-populated with the all known, trusted CA certificate files found in the Java system path. The openssl toolkit is used in the following example to generate a CA certificate to sign the HTTPS keystore, and create a truststore for the Red Hat Single Sign-On server. keytool , a package included with the Java Development Kit , is then utilized to the generate self-signed certificates for these keystores. Warning For production environments Red Hat recommends that you use your own SSL certificate purchased from a verified Certificate Authority (CA) for SSL-encrypted connections (HTTPS). See the JBoss Enterprise Application Platform Security Guide for more information on how to create a keystore with self-signed or purchased SSL certificates. Create the HTTPS keystore: Generate a CA certificate. Pick and remember the password. Provide identical password, when signing the certificate sign request with the CA certificate below: USD openssl req -new -newkey rsa:4096 -x509 -keyout xpaas.key -out xpaas.crt -days 365 -subj "/CN=xpaas-sso-demo.ca" Generate a private key for the HTTPS keystore. Provide mykeystorepass as the keystore password: USD keytool -genkeypair -keyalg RSA -keysize 2048 -dname "CN=secure-sso-sso-app-demo.openshift.example.com" -alias jboss -keystore keystore.jks Generate a certificate sign request for the HTTPS keystore. Provide mykeystorepass as the keystore password: USD keytool -certreq -keyalg rsa -alias jboss -keystore keystore.jks -file sso.csr Sign the certificate sign request with the CA certificate. Provide the same password that was used to generate the CA certificate : USD openssl x509 -req -CA xpaas.crt -CAkey xpaas.key -in sso.csr -out sso.crt -days 365 -CAcreateserial Import the CA certificate into the HTTPS keystore. Provide mykeystorepass as the keystore password. Reply yes to Trust this certificate? [no]: question: USD keytool -import -file xpaas.crt -alias xpaas.ca -keystore keystore.jks Import the signed certificate sign request into the HTTPS keystore. Provide mykeystorepass as the keystore password: USD keytool -import -file sso.crt -alias jboss -keystore keystore.jks Generate a secure key for the JGroups keystore: Provide password as the keystore password: USD keytool -genseckey -alias secret-key -storetype JCEKS -keystore jgroups.jceks Import the CA certificate into a new Red Hat Single Sign-On server truststore: Provide mykeystorepass as the truststore password. Reply yes to Trust this certificate? [no]: question: USD keytool -import -file xpaas.crt -alias xpaas.ca -keystore truststore.jks 4.1.3. Secrets OpenShift uses objects called secrets to hold sensitive information, such as passwords or keystores. Create the secrets for the HTTPS and JGroups keystores, and Red Hat Single Sign-On server truststore, generated in the section . USD oc create secret generic sso-app-secret --from-file=keystore.jks --from-file=jgroups.jceks --from-file=truststore.jks Link these secrets to the default service account, which is used to run Red Hat Single Sign-On pods. USD oc secrets link default sso-app-secret 4.1.4. Deploying the Chosen Red Hat Single Sign-On Passthrough TLS Template via OpenShift CLI After the aforementioned keystores and secrets are created, deploy some of the available passthrough TLS termination as follows: Warning For simplicity, the values of SSO_ADMIN_USERNAME , SSO_ADMIN_PASSWORD , HTTPS_PASSWORD , JGROUPS_ENCRYPT_PASSWORD , and SSO_TRUSTSTORE_PASSWORD variables in the following command have been chosen to match the default values of the respective parameters of the sso74-openj9-https Red Hat Single Sign-On application template. For production environments, Red Hat recommends that you consult the on-site policy, specific to your organization for guidance on how to generate sufficiently strong user name and password for the administrator user account of the Red Hat Single Sign-On server, and passwords for the HTTPS and JGroups keystores, and the truststore of the Red Hat Single Sign-On server. Be aware that the passwords provided when provisioning the template need to match the passwords provided when creating the keystores . If using different username and passwords, modify the values of respective template parameters as appropriate for your environment. Note The following commands using the keytool , a package included with the Java Development Kit , can be used to determine the names associated with the certificate: USD keytool -v -list -keystore keystore.jks | grep Alias Enter keystore password: mykeystorepass Alias name: xpaas.ca Alias name: jboss USD keytool -v -list -keystore jgroups.jceks -storetype jceks | grep Alias Enter keystore password: password Alias name: secret-key Finally, the SSO_ADMIN_USERNAME , SSO_ADMIN_PASSWORD , and the SSO_REALM template parameters in the following command are optional. USD oc new-app --template=sso74-openj9-https \ -p HTTPS_SECRET="sso-app-secret" \ -p HTTPS_KEYSTORE="keystore.jks" \ -p HTTPS_NAME="jboss" \ -p HTTPS_PASSWORD="mykeystorepass" \ -p JGROUPS_ENCRYPT_SECRET="sso-app-secret" \ -p JGROUPS_ENCRYPT_KEYSTORE="jgroups.jceks" \ -p JGROUPS_ENCRYPT_NAME="secret-key" \ -p JGROUPS_ENCRYPT_PASSWORD="password" \ -p SSO_ADMIN_USERNAME="admin" \ -p SSO_ADMIN_PASSWORD="redhat" \ -p SSO_REALM="demorealm" \ -p SSO_TRUSTSTORE="truststore.jks" \ -p SSO_TRUSTSTORE_PASSWORD="mykeystorepass" \ -p SSO_TRUSTSTORE_SECRET="sso-app-secret" --> Deploying template "openshift/sso74-openj9-https" to project sso-app-demo Red Hat Single Sign-On 7.4.10.GA (Ephemeral with passthrough TLS) --------- An example Red Hat Single Sign-On 7 application. For more information about using this template, see https://github.com/jboss-openshift/application-templates. A new Red Hat Single Sign-On service has been created in your project. The admin username/password for accessing the master realm via the Red Hat Single Sign-On console is admin/redhat. Please be sure to create the following secrets: "sso-app-secret" containing the keystore.jks file used for serving secure content; "sso-app-secret" containing the jgroups.jceks file used for securing JGroups communications; "sso-app-secret" containing the truststore.jks file used for securing Red Hat Single Sign-On requests. * With parameters: * Application Name=sso * Custom http Route Hostname= * Custom https Route Hostname= * Server Keystore Secret Name=sso-app-secret * Server Keystore Filename=keystore.jks * Server Keystore Type= * Server Certificate Name=jboss * Server Keystore Password=mykeystorepass * Datasource Minimum Pool Size= * Datasource Maximum Pool Size= * Datasource Transaction Isolation= * JGroups Secret Name=sso-app-secret * JGroups Keystore Filename=jgroups.jceks * JGroups Certificate Name=secret-key * JGroups Keystore Password=password * JGroups Cluster Password=yeSppLfp # generated * ImageStream Namespace=openshift * Red Hat Single Sign-On Administrator Username=admin * Red Hat Single Sign-On Administrator Password=redhat * Red Hat Single Sign-On Realm=demorealm * Red Hat Single Sign-On Service Username= * Red Hat Single Sign-On Service Password= * Red Hat Single Sign-On Trust Store=truststore.jks * Red Hat Single Sign-On Trust Store Password=mykeystorepass * Red Hat Single Sign-On Trust Store Secret=sso-app-secret * Container Memory Limit=1Gi --> Creating resources ... service "sso" created service "secure-sso" created service "sso-ping" created route "sso" created route "secure-sso" created deploymentconfig "sso" created --> Success Run 'oc status' to view your app. 4.2. Customizing the Hostname for the Red Hat Single Sign-On Server The hostname SPI introduced a flexible way to configure the hostname for the Red Hat Single Sign-On server. The default hostname provider one is default . This provider provides enhanced functionality over the original request provider which is now deprecated. Without additional settings, it uses the request headers to determine the hostname similarly to the original request provider. For configuration options of the default provider, refer to the Server Installation and Configuration Guide . The frontendUrl option can be configured via SSO_FRONTEND_URL environment variable. Note For backward compatibility, SSO_FRONTEND_URL settings is ignored if SSO_HOSTNAME is also set. Another option of hostname provider is fixed , which allows configuring a fixed hostname. The latter makes sure that only valid hostnames can be used and allows internal applications to invoke the Red Hat Single Sign-On server through an alternative URL. Run the following commands to set the fixed hostname SPI provider for the Red Hat Single Sign-On server: Deploy the Red Hat Single Sign-On for OpenShift image with SSO_HOSTNAME environment variable set to the desired hostname of the Red Hat Single Sign-On server. USD oc new-app --template=sso74-openj9-x509-https \ -p SSO_HOSTNAME="rh-sso-server.openshift.example.com" Identify the name of the route for the Red Hat Single Sign-On service. USD oc get routes NAME HOST/PORT sso sso-sso-app-demo.openshift.example.com Change the host: field to match the hostname specified as the value of the SSO_HOSTNAME environment variable above. Note Adjust the rh-sso-server.openshift.example.com value in the following command as necessary. If successful, the command will return the following output: 4.3. Connecting to an external database Red Hat Single Sign-On can be configured to connect to an external (to OpenShift cluster) database. In order to achieve this, you need to modify the sso-{database name} Endpoints object to point to the proper address. The procedure is described in the OpenShift manual . Tip: The easiest way to get started is to deploy Red Hat Single Sign-On from a template and then modify the Endpoints object. You might also need to update some of the datasource configuration variables in the DeploymentConfig. Once you're done, just roll a new deployment out. 4.4. Using Custom JDBC Driver To connect to any database, the JDBC driver for that database must be present and Red Hat Single Sign-On configured properly. Currently, the only JDBC driver available in the image is the PostgreSQL JDBC driver. For any other database, you need to extend the Red Hat Single Sign-On image with a custom JDBC driver and a CLI script to register it and set up the connection properties. The following steps illustrate how to do that, taking MariaDB driver as an example. Update the example for other database drivers accordingly. Create an empty directory. Download the JDBC driver binaries into this directory. Create a new Dockerfile file in this directory with the following contents. For other databases, replace mariadb-java-client-2.5.4.jar with the filename of the respective driver: Create a new sso-extensions.cli file in this directory with the following contents. Update the values of the variables in italics according to the deployment needs: batch set DB_DRIVER_NAME= mariadb set DB_USERNAME= username set DB_PASSWORD= password set DB_DRIVER= org.mariadb.jdbc.Driver set DB_XA_DRIVER= org.mariadb.jdbc.MariaDbDataSource set DB_JDBC_URL= jdbc:mariadb://jdbc-host/keycloak set DB_EAP_MODULE= org.mariadb set FILE=/opt/eap/extensions/jdbc-driver.jar module add --name=USDDB_EAP_MODULE --resources=USDFILE --dependencies=javax.api,javax.resource.api /subsystem=datasources/jdbc-driver=USDDB_DRIVER_NAME:add( \ driver-name=USDDB_DRIVER_NAME, \ driver-module-name=USDDB_EAP_MODULE, \ driver-class-name=USDDB_DRIVER, \ driver-xa-datasource-class-name=USDDB_XA_DRIVER \ ) /subsystem=datasources/data-source=KeycloakDS:remove() /subsystem=datasources/data-source=KeycloakDS:add( \ jndi-name=java:jboss/datasources/KeycloakDS, \ enabled=true, \ use-java-context=true, \ connection-url=USDDB_JDBC_URL, \ driver-name=USDDB_DRIVER_NAME, \ user-name=USDDB_USERNAME, \ password=USDDB_PASSWORD \ ) run-batch In this directory, build your image by typing the following command, replacing the project/name:tag with arbitrary name. docker can be used instead of podman . podman build -t docker-registry-default/project/name:tag . After the build finishes, push your image to the registry used by OpenShift to deploy your image. Refer to the OpenShift guide for details. 4.5. Creating the Administrator Account for Red Hat Single Sign-On Server Red Hat Single Sign-On does not provide any pre-configured management account out of the box. This administrator account is necessary for logging into the master realm's management console and perform server maintenance operations such as, creating realms or users, or registering applications intended to be secured by Red Hat Single Sign-On. The administrator account can be created: By providing values for the SSO_ADMIN_USERNAME and SSO_ADMIN_PASSWORD parameters , when deploying the Red Hat Single Sign-On application template, or By a remote shell session to particular Red Hat Single Sign-On pod , if the Red Hat Single Sign-On for OpenShift image is deployed without an application template. Note Red Hat Single Sign-On allows an initial administrator account to be created via the Welcome Page web form, but only if the Welcome Page is accessed from localhost; this method of administrator account creation is not applicable for the Red Hat Single Sign-On for OpenShift image. 4.5.1. Creating the Administrator Account Using Template Parameters When deploying Red Hat Single Sign-On application template, the SSO_ADMIN_USERNAME and SSO_ADMIN_PASSWORD parameters denote the username and password of the Red Hat Single Sign-On server's administrator account to be created for the master realm. Note Both of these parameters are required. If not specified, they are auto generated and displayed as an OpenShift instructional message when the template is instantiated. Important The lifespan of the Red Hat Single Sign-On server's administrator account depends upon the storage type used to store the Red Hat Single Sign-On server's database: For an in-memory database mode ( sso74-openj9-https and sso74-openj9-x509-https templates), the account exists throughout the lifecycle of the particular Red Hat Single Sign-On pod (stored account data is lost upon pod destruction), For an ephemeral database mode sso74-openj9-postgresql templates), the account exists throughout the lifecycle of the database pod. Even if the Red Hat Single Sign-On pod is destructed, the stored account data is preserved under the assumption that the database pod is still running, For persistent database mode ( sso74-openj9-postgresql-persistent , and sso74-openj9-x509-postgresql-persistent templates), the account exists throughout the lifecycle of the persistent medium used to hold the database data. This means that the stored account data is preserved even when both the Red Hat Single Sign-On and the database pods are destructed. It is a common practice to deploy an Red Hat Single Sign-On application template to get the corresponding OpenShift deployment config for the application, and then reuse that deployment config multiple times (every time a new Red Hat Single Sign-On application needs to be instantiated). Warning In the case of ephemeral or persistent database mode , after creating the RH_SSO server's administrator account, remove the SSO_ADMIN_USERNAME and SSO_ADMIN_PASSWORD variables from the deployment config before deploying new Red Hat Single Sign-On applications. Important Run the following commands to prepare the previously created deployment config of the Red Hat Single Sign-On application for reuse after the administrator account has been created: Identify the deployment config of the Red Hat Single Sign-On application. USD oc get dc -o name deploymentconfig/sso deploymentconfig/sso-postgresql Clear the SSO_ADMIN_USERNAME and SSO_ADMIN_PASSWORD variables setting. USD oc set env dc/sso \ -e SSO_ADMIN_USERNAME="" \ -e SSO_ADMIN_PASSWORD="" 4.5.2. Creating the Administrator Account via Remote Shell Session to Red Hat Single Sign-On Pod Run following commands to create an administrator account for the master realm of the Red Hat Single Sign-On server, when deploying the Red Hat Single Sign-On for OpenShift image directly from the image stream (without the template ), after the Red Hat Single Sign-On application pod has been started: Identify the Red Hat Single Sign-On application pod. USD oc get pods NAME READY STATUS RESTARTS AGE sso-12-pt93n 1/1 Running 0 1m sso-postgresql-6-d97pf 1/1 Running 0 2m Open a remote shell session to the Red Hat Single Sign-On for OpenShift container. USD oc rsh sso-12-pt93n sh-4.2USD Create the Red Hat Single Sign-On server administrator account for the master realm at the command line with the add-user-keycloak.sh script. sh-4.2USD cd /opt/eap/bin/ sh-4.2USD ./add-user-keycloak.sh \ -r master \ -u sso_admin \ -p sso_password Added 'sso_admin' to '/opt/eap/standalone/configuration/keycloak-add-user.json', restart server to load user Note The 'sso_admin' / 'sso_password' credentials in the example above are for demonstration purposes only. Refer to the password policy applicable within your organization for guidance on how to create a secure user name and password. Restart the underlying JBoss EAP server instance to load the newly added user account. Wait for the server to restart properly. sh-4.2USD ./jboss-cli.sh --connect ':reload' { "outcome" => "success", "result" => undefined } Warning When restarting the server it is important to restart just the JBoss EAP process within the running Red Hat Single Sign-On container, and not the whole container. This is because restarting the whole container will recreate it from scratch, without the Red Hat Single Sign-On server administration account for the master realm. Log in to the master realm's administration console of the Red Hat Single Sign-On server using the credentials created in the steps above. In the browser, navigate to http://sso-<project-name>.<hostname>/auth/admin for the Red Hat Single Sign-On web server, or to https://secure-sso-<project-name>.<hostname>/auth/admin for the encrypted Red Hat Single Sign-On web server, and specify the user name and password used to create the administrator user. 4.6. Customizing the default behavior of the Red Hat Single Sign-On image You can change the default behavior of the Red Hat Single Sign-On image such as enabling TechPreview features or enabling debugging. This section describes how to make this change by using the JAVA_OPTS_APPEND variable. Prerequisites This procedure assumes that the Red Hat Single Sign-On for OpenShift image has been previously deployed using one of the following templates: sso74-openj9-postgresql sso74-openj9-postgresql-persistent sso74-openj9-x509-postgresql-persistent Procedure You can use the OpenShift web console or the CLI to change the default behavior. If you use the OpenShift web console, you add the JAVA_OPTS_APPEND variable to the sso deployment config. For example, to enable TechPreview features, you set the variable as follows: JAVA_OPTS_APPEND="-Dkeycloak.profile=preview" If you use the CLI, use the following commands to enable TechPreview features when the Red Hat Single Sign-On pod was deployed using a template that is mentioned under Prerequisites. Scale down the Red Hat Single Sign-On pod: USD oc get dc -o name deploymentconfig/sso deploymentconfig/sso-postgresql USD oc scale --replicas=0 dc sso deploymentconfig "sso" scaled Note In the preceding command, sso-postgresql appears because a PostgreSQL template was used to deploy the Red Hat Single Sign-On for OpenShift image. Edit the deployment config to set the JAVA_OPTS_APPEND variable. For example, to enable TechPreview features, you set the variable as follows: oc env dc/sso -e "JAVA_OPTS_APPEND=-Dkeycloak.profile=preview" Scale up the Red Hat Single Sign-On pod: USD oc scale --replicas=1 dc sso deploymentconfig "sso" scaled Test a TechPreview feature of your choice. 4.7. Deployment Process Once deployed, the sso74-openj9-https and sso74-openj9-x509-https templates create a single pod that contains both the database and the Red Hat Single Sign-On servers. The sso74-openj9-postgresql , sso74-openj9-postgresql-persistent , and sso74-openj9-x509-postgresql-persistent templates create two pods, one for the database server and one for the Red Hat Single Sign-On web server. After the Red Hat Single Sign-On web server pod has started, it can be accessed at its custom configured hostnames, or at the default hostnames: http://sso- <project-name> . <hostname> /auth/admin : for the Red Hat Single Sign-On web server, and https://secure-sso- <project-name> . <hostname> /auth/admin : for the encrypted Red Hat Single Sign-On web server. Use the administrator user credentials to log in into the master realm's administration console. 4.8. Red Hat Single Sign-On Clients Clients are Red Hat Single Sign-On entities that request user authentication. A client can be an application requesting Red Hat Single Sign-On to provide user authentication, or it can be making requests for access tokens to start services on behalf of an authenticated user. See the Managing Clients chapter of the Red Hat Single Sign-On documentation for more information. Red Hat Single Sign-On provides OpenID-Connect and SAML client protocols. OpenID-Connect is the preferred protocol and utilizes three different access types: public : Useful for JavaScript applications that run directly in the browser and require no server configuration. confidential : Useful for server-side clients, such as EAP web applications, that need to perform a browser login. bearer-only : Useful for back-end services that allow bearer token requests. It is required to specify the client type in the <auth-method> key of the application web.xml file. This file is read by the image at deployment. Set the value of <auth-method> element to: KEYCLOAK for the OpenID Connect client. KEYCLOAK-SAML for the SAML client. The following is an example snippet for the application web.xml to configure an OIDC client: ... <login-config> <auth-method>KEYCLOAK</auth-method> </login-config> ... 4.8.1. Automatic and Manual Red Hat Single Sign-On Client Registration Methods A client application can be automatically registered to an Red Hat Single Sign-On realm by using credentials passed in variables specific to the eap64-sso-s2i , eap71-sso-s2i , and datavirt63-secure-s2i templates. Alternatively, you can manually register the client application by configuring and exporting the Red Hat Single Sign-On client adapter and including it in the client application configuration. 4.8.1.1. Automatic Red Hat Single Sign-On Client Registration Automatic Red Hat Single Sign-On client registration is determined by Red Hat Single Sign-On environment variables specific to the eap64-sso-s2i , eap71-sso-s2i , and datavirt63-secure-s2i templates. The Red Hat Single Sign-On credentials supplied in the template are then used to register the client to the Red Hat Single Sign-On realm during deployment of the client application. The Red Hat Single Sign-On environment variables included in the eap64-sso-s2i , eap71-sso-s2i , and datavirt63-secure-s2i templates are: Variable Description HOSTNAME_HTTP Custom hostname for http service route. Leave blank for default hostname of <application-name>.<project>.<default-domain-suffix> HOSTNAME_HTTPS Custom hostname for https service route. Leave blank for default hostname of <application-name>.<project>.<default-domain-suffix> SSO_URL The Red Hat Single Sign-On web server authentication address: https://secure-sso- <project-name> . <hostname> /auth SSO_REALM The Red Hat Single Sign-On realm created for this procedure. SSO_USERNAME The name of the realm management user . SSO_PASSWORD The password of the user. SSO_PUBLIC_KEY The public key generated by the realm. It is located in the Keys tab of the Realm Settings in the Red Hat Single Sign-On console. SSO_BEARER_ONLY If set to true , the OpenID Connect client is registered as bearer-only. SSO_ENABLE_CORS If set to true , the Red Hat Single Sign-On adapter enables Cross-Origin Resource Sharing (CORS). If the Red Hat Single Sign-On client uses the SAML protocol, the following additional variables need to be configured: Variable Description SSO_SAML_KEYSTORE_SECRET Secret to use for access to SAML keystore. The default is sso-app-secret . SSO_SAML_KEYSTORE Keystore filename in the SAML keystore secret. The default is keystore.jks . SSO_SAML_KEYSTORE_PASSWORD Keystore password for SAML. The default is mykeystorepass . SSO_SAML_CERTIFICATE_NAME Alias for keys/certificate to use for SAML. The default is jboss . See Example Workflow: Automatically Registering EAP Application in Red Hat Single Sign-On with OpenID-Connect Client for an end-to-end example of the automatic client registration method using an OpenID-Connect client. 4.8.1.2. Manual Red Hat Single Sign-On Client Registration Manual Red Hat Single Sign-On client registration is determined by the presence of a deployment file in the client application's ../configuration/ directory. These files are exported from the client adapter in the Red Hat Single Sign-On web console. The name of this file is different for OpenID-Connect and SAML clients: OpenID-Connect ../configuration/secure-deployments SAML ../configuration/secure-saml-deployments These files are copied to the Red Hat Single Sign-On adapter configuration section in the standalone-openshift.xml at when the application is deployed. There are two methods for passing the Red Hat Single Sign-On adapter configuration to the client application: Modify the deployment file to contain the Red Hat Single Sign-On adapter configuration so that it is included in the standalone-openshift.xml file at deployment, or Manually include the OpenID-Connect keycloak.json file, or the SAML keycloak-saml.xml file in the client application's ../WEB-INF directory. See Example Workflow: Manually Configure an Application to Use Red Hat Single Sign-On Authentication, Using SAML Client for an end-to-end example of the manual Red Hat Single Sign-On client registration method using a SAML client. 4.9. Using Red Hat Single Sign-On vault with OpenShift secrets Several fields in the Red Hat Single Sign-On administration support obtaining the value of a secret from an external vault, see Server Administration Guide . The following example shows how to set up the files plaintext vault in OpenShift and set it up to be used for obtaining an SMTP password. Specify a directory for the vault using the SSO_VAULT_DIR environment variable. You can introduce the SSO_VAULT_DIR environment variable directly in the environment in your deployment configuration. It can also be included in the template by addding the following snippets at the appropriate places in the template: "parameters": [ ... { "displayName": "RH-SSO Vault Secret directory", "description": "Path to the RH-SSO Vault directory.", "name": "SSO_VAULT_DIR", "value": "", "required": false } ... ] env: [ ... { "name": "SSO_VAULT_DIR", "value": "USD{SSO_VAULT_DIR}" } ... ] Note The files plaintext vault provider will be configured only when you set SSO_VAULT_DIR environment variable. Create a secret in your OpenShift cluster: USD oc create secret generic rhsso-vault-secrets --from-literal=master_smtp-password=mySMTPPsswd Mount a volume to your deployment config using the USD{SSO_VAULT_DIR} as the path. For a deployment that is already running: oc set volume dc/sso --add --mount-path=USD{SSO_VAULT_DIR} --secret-name=rhsso-vault-secrets After a pod is created you can use a customized string within your Red Hat Single Sign-On configuration to refer to the secret. For example, for using mySMTPPsswd secret created in this tutorial, you can use USD{vault.smtp-password} within the master realm in the configuration of the smtp password and it will be replaced by mySMTPPsswd when used. 4.10. Limitations OpenShift does not currently accept OpenShift role mapping from external providers. If Red Hat Single Sign-On is used as an authentication gateway for OpenShift, users created in Red Hat Single Sign-On must have the roles added using the OpenShift Administrator oc adm policy command. For example, to allow an Red Hat Single Sign-On-created user to view a project namespace in OpenShift: USD oc adm policy add-role-to-user view < user-name > -n < project-name >

Commands:
