Chapter 8. Reference 8.1. Custom Resource configuration reference A Custom Resource Definition (CRD) is a schema of configuration items for a custom OpenShift object deployed with an Operator. By deploying a corresponding Custom Resource (CR) instance, you specify values for configuration items shown in the CRD. The following sub-sections detail the configuration items that you can set in Custom Resource instances based on the main broker CRD. 8.1.1. Broker Custom Resource configuration reference A CR instance based on the main broker CRD enables you to configure brokers for deployment in an OpenShift project. The following table describes the items that you can configure in the CR instance. Important Configuration items marked with an asterisk ( * ) are required in any corresponding Custom Resource (CR) that you deploy. If you do not explicitly specify a value for a non-required item, the configuration uses the default value. Table 8.1. Broker CR reference Entry Sub-entry Description and usage adminUser* Administrator user name required for connecting to the broker and management console. If you do not specify a value, the value is automatically generated and stored in a secret. The default secret name has a format of <custom_resource_name> -credentials-secret . For example, my-broker-deployment-credentials-secret . Type : string Example : my-user Default value : Automatically-generated, random value adminPassword* Administrator password required for connecting to the broker and management console. If you do not specify a value, the value is automatically generated and stored in a secret. The default secret name has a format of <custom_resource_name> -credentials-secret . For example, my-broker-deployment-credentials-secret . Type : string Example : my-password Default value : Automatically-generated, random value ingressDomain Append a custom domain to the host name in routes and ingresses that are created for acceptors, connectors and the management console. Type : string Example : mydomain.com deploymentPlan* Broker deployment configuration image* Full path of the broker container image used for each broker in the deployment. You do not need to explicitly specify a value for image in your CR. The default value of placeholder indicates that the Operator has not yet determined the appropriate image to use. To learn how the Operator chooses a broker container image to use, see Section 2.7, "How the Operator chooses container images" . Type : string Example : registry.redhat.io/amq7/amq-broker-rhel8@sha256:55ae4e28b100534d63c34ab86f69230d274c999d46d1493f26fe3e75ba7a0cec Default value : placeholder size* Number of broker Pods to create in the deployment. If you specify a value of 2 or greater, your broker deployment is clustered by default. The cluster user name and password are automatically generated and stored in the same secret as adminUser and adminPassword , by default. Type : int Example : 1 Default value : 1 requireLogin Specify whether login credentials are required to connect to the broker. Type : Boolean Example : false Default value : true persistenceEnabled Specify whether to use journal storage for each broker Pod in the deployment. If set to true , each broker Pod requires an available Persistent Volume (PV) that the Operator can claim using a Persistent Volume Claim (PVC). Type : Boolean Example : false Default value : true initImage Init Container image used to configure the broker. You do not need to explicitly specify a value for initImage in your CR, unless you want to provide a custom image. To learn how the Operator chooses a built-in Init Container image to use, see Section 2.7, "How the Operator chooses container images" . To learn how to specify a custom Init Container image, see Section 4.11, "Specifying a custom Init Container image" .

Consult a cluster administrator. resources.limits.memory Maximum amount of host-node memory, in bytes, that each broker container running in a Pod in a deployment can consume. Supports byte notation (for example, K, M, G), or the binary equivalents (Ki, Mi, Gi). Type : string Example : "1024M" Default value : Uses the same default value that your version of OpenShift Container Platform uses. Consult a cluster administrator. resources.requests.cpu Amount of host-node CPU, in millicores, that each broker container running in a Pod in a deployment explicitly requests. Type : string Example : "250m" Default value : Uses the same default value that your version of OpenShift Container Platform uses. Consult a cluster administrator. resources.requests.memory Amount of host-node memory, in bytes, that each broker container running in a Pod in a deployment explicitly requests. Supports byte notation (for example, K, M, G), or the binary equivalents (Ki, Mi, Gi). Type : string Example : "512M" Default value : Uses the same default value that your version of OpenShift Container Platform uses. Consult a cluster administrator. storage.size Size, in bytes, of the Persistent Volume Claim (PVC) that each broker in a deployment requires for persistent storage.

Type : string Example : amq-broker-controller-manager Default value : default console Configuration of broker management console. expose Specify whether to expose the management console to clients outside OpenShift Container Platform. Type : Boolean Example : true Default value : false exposeMode Specify whether to expose the management console by using a route or an ingress. By default, the management console is exposed by using a route only. Type : String Example : ingress Default value : route If you expose the console by using an ingress, you must specify an ingressHost or an ingressDomain value in the CR. ingressHost Specify a custom host value for routes and ingresses exposed for the management console. You can include any the following variables in the host value: * USD(CR_NAME) - The value of the metadata.name attribute in the CR. * USD(CR_NAMESPACE) - The namespace of the custom resource. * USD(BROKER_ORDINAL) - The ordinal number assigned to the broker pod by the StatefulSet. * USD(ITEM_NAME) - The name of the console. The default name is wconsj * USD(RES_TYPE) - The resource type. A route has a resource type of rte . An ingress has a resource type of ing . * USD(INGRESS_DOMAIN) - The value of the spec.ingressDomain attribute if it is configured in the CR. Type : string Example : console-USD(CR_NAME)-USD(ITEM_NAME)-USD(BROKER_ORDINAL).mydomain.com sslEnabled Specify whether to use SSL on the management console port. Type : Boolean Example : true Default value : false sslSecret Secret where broker key store, trust store, and their corresponding passwords (all Base64-encoded) are stored.

The default value then increments by 10 for every subsequent acceptor that you define. protocols Messaging protocols to be enabled on the acceptor instance. Type : string Example : amqp,core Default value : all sslEnabled Specify whether SSL is enabled on the acceptor port. If set to true , look in the secret name specified in sslSecret for the credentials required by TLS/SSL. Type : Boolean Example : true Default value : false sslSecret Secret where broker key store, trust store, and their corresponding passwords (all Base64-encoded) are stored. If you do not specify a custom secret name for sslSecret , the acceptor assumes a default secret name. The default secret name has a format of <custom_resource_name> - <acceptor_name> -secret . You must always create this secret yourself, even when the acceptor assumes a default name. Type : string Example : my-broker-deployment-my-acceptor-secret Default value : <custom_resource_name> - <acceptor_name> -secret enabledCipherSuites Comma-separated list of cipher suites to use for TLS communication. Specify the most secure cipher suite(s) supported by your client application. If you specify a comma-separated list of cipher suites that are common to both the broker and the client, or you do not specify any cipher suites, the broker and client mutually negotiate a cipher suite to use. If you do not know which cipher suites to specify, you can first establish a broker-client connection with your client running in debug mode to verify the cipher suites that are common to both the broker and the client. Then, configure enabledCipherSuites on the broker. The cipher suites available depend on the TLS protocol versions used by the broker and clients. If the default TLS protocol version changes after you upgrade the broker, you might need to select an earlier TLS protocol version to ensure that the broker and the clients can use a common cipher suite. For more information, see enabledProtocols . Type : string Default value : Not specified enabledProtocols Comma-separated list of protocols to use for TLS communication. Type : string Example : TLSv1,TLSv1.1,TLSv1.2 Default value : Not specified If you don't specify a TLS protocol version, the broker uses the JVM's default version. If the broker uses the JVM's default TLS protocol version and that version changes after you upgrade the broker, the TLS protocol versions used by the broker and clients might be incompatible. While it is recommended that you use the later TLS protocol version, you can specify an earlier version in enabledProtocols to interoperate with clients that do not support a newer TLS protocol version. keyStoreProvider The name of the provider of the keystore that the broker uses. Type : string Example : SunJCE Default value : Not specified trustStoreProvider The name of the provider of the truststore that the broker uses. Type : string Example : SunJCE Default value : Not specified trustStoreType The type of truststore that the broker uses.

Type : string Example : my-acceptor-USD(CR_NAME)-USD(ITEM_NAME)-USD(BROKER_ORDINAL).mydomain.com anycastPrefix Prefix used by a client to specify that the anycast routing type should be used. Type : string Example : jms.queue Default value : Not specified multicastPrefix Prefix used by a client to specify that the multicast routing type should be used. Type : string Example : /topic/ Default value : Not specified connectionsAllowed Number of connections allowed on the acceptor. When this limit is reached, a DEBUG message is issued to the log, and the connection is refused. The type of client in use determines what happens when the connection is refused. Type : integer Example : 2 Default value : 0 (unlimited connections) amqpMinLargeMessageSize Minimum message size, in bytes, required for the broker to handle an AMQP message as a large message. If the size of an AMQP message is equal or greater to this value, the broker stores the message in a large messages directory ( /opt/ <custom_resource_name> /data/large-messages , by default) on the persistent volume (PV) used by the broker for message storage. Setting the value to -1 disables large message handling for AMQP messages. Type : integer Example : 204800 Default value : 102400 (100 KB) BindToAllInterfaces If set to true, configures the broker acceptors with a 0.0.0.0 IP address instead of the internal IP address of the pod. When the broker acceptors have a 0.0.0.0 IP address, they bind to all interfaces configured for the pod and clients can direct traffic to the broker by using OpenShift Container Platform port-forwarding. Normally, you use this configuration to debug a service. For more information about port-forwarding, see Using port-forwarding to access applications in a container in the OpenShift Container Platform documentation. Note If port-forwarding is used incorrectly, it can create a security risk for your environment. Where possible, do not use port-forwarding in a production environment.

If set to true , look in the secret name specified in sslSecret for the credentials required by TLS/SSL. Type : Boolean Example : true Default value : false sslSecret Secret where broker key store, trust store, and their corresponding passwords (all Base64-encoded) are stored. If you do not specify a custom secret name for sslSecret , the connector assumes a default secret name. The default secret name has a format of <custom_resource_name> - <connector_name> -secret . You must always create this secret yourself, even when the connector assumes a default name. Type : string Example : my-broker-deployment-my-connector-secret Default value : <custom_resource_name> - <connector_name> -secret enabledCipherSuites Comma-separated list of cipher suites to use for TLS communication.

Example JAAS login module configurations The following example shows a JAAS login module configuration that has both a properties login module and an LDAP login module configured. The properties login module references the default login module that contains the credentials used by the Operator to authenticate with the broker. activemq { org.apache.activemq.artemis.spi.core.security.jaas.LDAPLoginModule required debug=true initialContextFactory=com.sun.jndi.ldap.LdapCtxFactory connectionURL="LDAP://localhost:389" connectionUsername="CN=Administrator,CN=Users,OU=System,DC=example,DC=com" connectionPassword=redhat.123 connectionProtocol=s connectionTimeout="5000" authentication=simple userBase="dc=example,dc=com" userSearchMatching="(CN={0})" userSearchSubtree=true readTimeout="5000" roleBase="dc=example,dc=com" roleName=cn roleSearchMatching="(member={0})" roleSearchSubtree=true; org.apache.activemq.artemis.spi.core.security.jaas.PropertiesLoginModule reload=true org.apache.activemq.jaas.properties.user="artemis-users.properties" org.apache.activemq.jaas.properties.role="artemis-roles.properties" baseDir="/home/jboss/amq-broker/etc"; }; The following example shows a JAAS login module configuration that has two properties login modules in separate realms. The default properties login module is in a realm named console and has the properties files that are used by the Operator and AMQ Management Console to authenticate with the broker. The login module in the activemq realm has new properties files, which, for example, could contain the credentials to authenticate users for messaging. You might want to create separate realms to, for example, apply specific security controls to the realm that contains the login module used by the Operator to authenticate with the broker. activemq { org.apache.activemq.artemis.spi.core.security.jaas.PropertiesLoginModule reload=true org.apache.activemq.jaas.properties.user="new-users.properties" org.apache.activemq.jaas.properties.role="new-roles.properties" }; console { org.apache.activemq.artemis.spi.core.security.jaas.PropertiesLoginModule reload=true org.apache.activemq.jaas.properties.user="artemis-users.properties" org.apache.activemq.jaas.properties.role="artemis-roles.properties" baseDir="/home/jboss/amq-broker/etc"; }; Note By default, AMQ Management Console uses the default properties login module in the activemq realm for authentication. If the default properties login module is configured in another realm, as in the example, you must set an environment variable in the broker CR to configure AMQ Management Console to use that realm. For example: spec: ... env: - name: JAVA_ARGS_APPEND value: --Hawtio.realm=console ... For more information about setting environment variables in a CR, see Section 4.9, "Setting environment variables for the broker containers" . 8.3. Example: configuring AMQ Broker to use Red Hat Single Sign-On This example shows how to configure AMQ Broker to use Red Hat Single Sign-On for authentication and authorization by using JAAS login modules. Prerequisites A Red Hat Single Sign-On instance integrated with an LDAP directory. The LDAP directory is populated with users and role information for AMQ Broker. Red Hat Single Sign-On is configured to federate users from the LDAP server. Red Hat Single Sign-On is configured to use the role-ldap-mapper to map role information from LDAP to Red Hat Single Sign-On. A Red Hat Single Sign-On realm that has: A client configured with the following settings for applications, such as AMQ Management Console, that can use the oAuth protocol to obtain a token: Authentication flow: Standard flow Valid Redirect URIs: An OpenShift Container Platform route for AMQ Management Console. For example, http://artemis-wconsj-0-svc-rte-kc-ldap-tests-0eae49.apps.redhat-412t.broker.app-services-dev.net/console/* A separate client configured with the following settings if you have messaging client applications that cannot use the oAuth protocol to obtain a token: Authentication flow: Direct Access Grants Valid Redirect URIs: * Note Each realm in Red Hat Single Sign-On includes a client named Broker . This client is not related to AMQ Broker. Procedure Create a text file named login.config and add the JAAS login module configuration to connect AMQ Broker with Red Hat Single Sign-On. For example: Note The path to the .json configuration files must be in the format /amq/extra/secrets/ name -jaas-config . For name , specify a string value. You must use the same string value and a -jaas-config suffix to name the secret that you create later in this procedure. In the example login.config file, a realm named console is used to authenticate AMQ Management Console users and a realm named activemq to authenticate messaging clients. The following login modules are configured in the example login.config file. Table 8.4. Login modules Login module Description and usage org.apache.activemq.artemis.spi.core.security.jaas.PropertiesLoginModule This is the default login module and contains the artemis-users.properties file, which contains a default user that is required by the Operator to authenticate with the broker. org.keycloak.adapters.jaas.BearerTokenLoginModule This login module is for applications, for example, AMQ Management Console, that can use the oAuth protocol to obtain a token. When a user opens AMQ Management Console in a browser window, they are redirected to the Red Hat Single Sign-On console to log in to obtain a bearer token. org.keycloak.adapters.jaas.DirectAccessGrantsLoginModule This login module is required for non-HTTP applications, such as messaging clients, which cannot use the oAuth protocol. Using this login module, the broker first authenticates the client using a secret that is configured in Red Hat Single Sign-On and then obtains a token on behalf of the client. org.apache.activemq.artemis.spi.core.security.jaas.PrincipalConversionLoginModule This login module is required to convert the Keycloak principal received into a JAAS principal that can be used by AMQ Broker. Note In the login.config file example, each .json properties file name has an underscore prefix. The Operator ignores files prefixed with an underscore when it reports the status of the JaasPropertiesApplied condition. If the file names do not have an underscore prefix, the status of the JaasPropertiesApplied condition shows OutofSync permanently because the broker does not recognize properties files used by third party login modules. For more information about status reporting, see Section 4.3.2.1, "Configuring the default JAAS login module using the Security Custom Resource (CR)" . Create text files for each of the .json properties files that are referenced in the login modules and configure the details required to connect AMQ Broker to Red Hat Single Sign-On. For example: _keycloak-bearer-token.json _keycloak-direct-access.json realm The realm configured to authenticate the AMQ Broker applications and services in Red Hat Single Sign-On. resource The client ID of a client that is configured in Red Red Hat Single Sign-On. auth-server-url The base URL of the Red Hat Single Sign-On server. principal-attribute The token attribute with which to populate the UserPrincipal name. use-resource-role-mappings If set to true, Red Hat Single Sign-On looks inside the token for application level role mappings for the user. If false, it looks at the realm level for user role mappings. The default value is false. ssl-required Ensures that all communication to and from the Red Hat Single Sign-On server is over HTTPS. The default value is external , which means that HTTPS is required by default for external requests. credentials A secret configured in Red Hat Single Sign-On which the broker uses to log in to Red Hat Single Sign-On and obtain a token on behalf of the client. Create a text file named _keycloak-js-client.json and add the configuration required for AMQ Management Console to redirect users to the URL of the Red Hat Single Sign-On Admin Console, where they enter their credentials. For example: Use the oc create secret command to create a secret that contains the files that are referenced in the login module configuration. For example: Note The secret name must have a suffix of -jaas-config so the Operator can recognize that the secret contains login module configuration and propagate any updates to each broker Pod. The secret name must match the last directory name in the path to the .json configuration files, which you specified in the login.config file. For example, if the path to the configuration files is /amq/extra/secrets/sso-jaas-config , you must specify a secret name of sso-jaas-config . For more information about how to create secrets, see Secrets in the Kubernetes documentation. Add the secret you created to the ActiveMQArtemis Custom Resource (CR) instance for your broker deployment. Using the OpenShift command-line interface: Log in to OpenShift as a user that has privileges to deploy CRs in the project for the broker deployment. Edit the CR for your deployment. Using the OpenShift Container Platform web console: Log in to the console as a user that has privileges to deploy CRs in the project for the broker deployment. In the left pane, click Operators Installed Operator . Click the Red Hat Integration - AMQ Broker for RHEL 8 (Multiarch) operator. Click the AMQ Broker tab. Click the name of the ActiveMQArtemis instance name. Click the YAML tab. Within the console, a YAML editor opens, enabling you to configure a CR instance. Create an extraMounts attribute and a secrets attribute and add the name of the secret. The following example adds a secret named custom-jaas-config to the CR. deploymentPlan: ... extraMounts: secrets: - "sso-jaas-config" ... In the ActiveMQArtemis CR, create an environment variable that contains the hawtio settings required by AMQ Management Console to use Red Hat Single Sign-On for authentication. The contents of the environment variable are passed as arguments to the Java application launcher when the JVM that hosts a broker is started. For example: env: - name: JAVA_ARGS_APPEND value: -Dhawtio.rolePrincipalClasses=org.apache.activemq.artemis.spi.core.security.jaas.RolePrincipal -Dhawtio.keycloakEnabled=true -Dhawtio.keycloakClientConfig=/amq/extra/secrets/sso-jaas-config/_keycloak-js-client.json -Dhawtio.authenticationEnabled=true -Dhawtio.realm=console For more information on hawtio settings, see the hawtio documentation . In the spec section of the ActiveMQArtemis CR, add a brokerProperties attribute and add permissions for the roles configured in the LDAP directory. You can grant a role permissions to a single address. Or, you can specify a wildcard match using the # sign to grant a role permissions to all addresses. For example: spec: ... brokerProperties: - securityRoles.#.producers.send=true - securityRoles.#.consumers.consume=true ... Save the CR. The Operator mounts the files in the secret in a /amq/extra/secrets/ secret name directory on each Pod and configures the broker JVM to read the mounted login.config file, which contains the SSO configuration, instead of the default login.config file. 8.4. Logging In addition to viewing the OpenShift logs, you can troubleshoot a running AMQ Broker on OpenShift Container Platform image by viewing the AMQ logs that are output to the container's console. Procedure At the command line, run the following command: Revised on 2025-03-18 14:05:25 UTC
