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.

EntrySub-entryDescription 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:dc13871dfed52402c40fd192900fc3cb5a49da4fa08e4ec4d0e23a879e83db25

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.

Default value: 1

 

requireLogin

Specify whether login credentials are required to connect to the broker.

Type: Boolean

Example: false

Default value: true

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”.

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.

Type: Boolean

Example: true

Default value: Not specified

 

verifyHost

Specify whether to compare the Common Name (CN) of a client’s certificate to its host name, to verify that they match. This option applies only when two-way TLS is used.

Specify whether to expose the acceptor to clients outside OpenShift Container Platform.

Type: Boolean

Example: true

Default value: false

 

exposeMode

Specify whether to expose the acceptor by using a route or an ingress. By default, an acceptor is exposed using a route only.

Type: String

Example: ingress

Default value: route

If you expose a connector by using an ingress, you must include the ingressHost or the ingressDomain attribute in the CR.

 

ingressHost

Specify a custom host value for routes and ingress exposed for the acceptor. You can include any of the following variables for the host:

* $(CR_NAME) - The value of the metadata.name attribute in the CR.

* $(CR_NAMESPACE) - The namespace of the custom resource.

* $(BROKER_ORDINAL) - The ordinal number assigned to the broker pod by the StatefulSet.

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.

8.2. 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

  1. 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:

    console {
        // ensure the operator can connect to the broker by referencing the existing properties config
        org.apache.activemq.artemis.spi.core.security.jaas.PropertiesLoginModule sufficient
            org.apache.activemq.jaas.properties.user="artemis-users.properties"
            org.apache.activemq.jaas.properties.role="artemis-roles.properties"
            baseDir="/home/jboss/amq-broker/etc";
    
       org.keycloak.adapters.jaas.BearerTokenLoginModule sufficient
            keycloak-config-file="/amq/extra/secrets/sso-jaas-config/_keycloak-bearer-token.json"
            role-principal-class=org.apache.activemq.artemis.spi.core.security.jaas.RolePrincipal;
    };
    activemq {
        org.keycloak.adapters.jaas.BearerTokenLoginModule sufficient
            keycloak-config-file="/amq/extra/secrets/sso-jaas-config/_keycloak-bearer-token.json"
            role-principal-class=org.apache.activemq.artemis.spi.core.security.jaas.RolePrincipal;
    
        org.keycloak.adapters.jaas.DirectAccessGrantsLoginModule sufficient
            keycloak-config-file="/amq/extra/secrets/sso-jaas-config/_keycloak-direct-access.json"
            role-principal-class=org.apache.activemq.artemis.spi.core.security.jaas.RolePrincipal;
    
        org.apache.activemq.artemis.spi.core.security.jaas.PrincipalConversionLoginModule required
           principalClassList=org.keycloak.KeycloakPrincipal;
    };
    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.

Login moduleDescription 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)”.

  1. 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
    {
        "realm": "amq-broker-ldap",
        "resource": "amq-console",
        "auth-server-url": "https://keycloak-svc-rte-kc-ldap-tests-0eae49.apps.412t.broker.app-services-dev.net",
        "principal-attribute": "preferred_username",
        "use-resource-role-mappings": false,
        "ssl-required": "external",
        "confidential-port": 0
    }
    _keycloak-direct-access.json
    {
        "realm": "amq-broker-ldap",
        "resource": "amq-broker",
        "auth-server-url": "https://keycloak-svc-rte-kc-ldap-tests-0eae49.apps.412t.broker.app-services-dev.net",
        "principal-attribute": "preferred_username",
        "use-resource-role-mappings": false,
        "ssl-required": "external",
        "credentials": {
            "secret": "Lfk6g1ZKlGzNT6eRkz0d1scM4M29Ohmn"
        }
    }
    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.
  2. 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:

    {
      "realm": "amq-broker-ldap",
      "clientId": "amq-console",
      "url": "https://keycloak-svc-rte-kc-ldap-tests-0eae49.apps.412t.broker.app-services-dev.net"
    }
  3. Use the oc create secret command to create a secret that contains the files that are referenced in the login module configuration. For example:

    oc create secret generic sso-jaas-config --from-file=login.config --from-file=artemis-users.properties --from-file=artemis-roles.properties --from-file=_keycloak-bearer-token.json --from-file=_keycloak-direct-access.json --from-file=_keycloak-js-client.json
    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.

  4. Add the secret you created to the ActiveMQArtemis Custom Resource (CR) instance for your broker deployment.

    1. Using the OpenShift command-line interface:

      1. Log in to OpenShift as a user that has privileges to deploy CRs in the project for the broker deployment.
      2. Edit the CR for your deployment.

         oc edit ActiveMQArtemis <CR instance name> -n <namespace>
    2. Using the OpenShift Container Platform web console:

      1. Log in to the console as a user that has privileges to deploy CRs in the project for the broker deployment.
      2. In the left pane, click Operators Installed Operator.
      3. Click the Red Hat Integration - AMQ Broker for RHEL 8 (Multiarch) operator.
      4. Click the AMQ Broker tab.
      5. Click the name of the ActiveMQArtemis instance name.
      6. Click the YAML tab.

        Within the console, a YAML editor opens, enabling you to configure a CR instance.

  5. 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"
      ...
  6. 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.

  7. 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
      ...
  8. 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:
$ oc logs -f <pass:quotes[<pod-name>]> <pass:quotes[<container-name>]>
