10.1. 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 and addressing CRDs.

10.1.1. 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

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.

If you use a comma-separated list to specify a set of cipher suites that is 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, it is recommended that you 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.

Specifies the name of the broker instance. The default value is amq-broker.

AMQ_PASSWORD

Specifies the password used for authentication to the broker. The AMQ Broker application templates use the value of this parameter stored in the secret named in AMQ_CREDENTIAL_SECRET.

AMQ_PROTOCOL

Specifies the messaging protocols used by the broker in a comma-separated list. Available options are amqp, mqtt, openwire, stomp, and hornetq. If none are specified, all protocols are available. Note that for integration of the image with Red Hat JBoss Enterprise Application Platform, the OpenWire protocol must be specified, while other protocols can be optionally specified as well.

AMQ_QUEUES

Specifies the queues available by default on the broker on its startup, in a comma-separated list.

AMQ_REQUIRE_LOGIN

If set to true, login is required. If not specified, or set to false, anonymous access is permitted. By default, the value of this parameter is not specified.

AMQ_ROLE

Specifies the name for the role created. The default value is amq.

AMQ_TRUSTSTORE

Specifies the SSL truststore file name. If no value is specified, a random password is generated but SSL will not be configured.

AMQ_TRUSTSTORE_PASSWORD

(Optional) Specifies the password used to decrypt the SSL truststore. The AMQ Broker application templates use the value of this parameter stored in the secret named in AMQ_CREDENTIAL_SECRET.

AMQ_USER

Specifies the user name used for authentication to the broker. The AMQ Broker application templates use the value of this parameter stored in the secret named in AMQ_CREDENTIAL_SECRET.

APPLICATION_NAME

Specifies the name of the application used internally within OpenShift. It is used in names of services, pods, and other objects within the application.

IMAGE

Specifies the image. Used in the persistence, persistent-ssl, and statefulset-clustered templates.

IMAGE_STREAM_NAMESPACE

Specifies the image stream name space. Used in the ssl and basic templates.

OPENSHIFT_DNS_PING_SERVICE_PORT

Specifies the port number for the OpenShift DNS ping service.

PING_SVC_NAME

Specifies the name of the OpenShift DNS ping service. The default value is $APPLICATION_NAME-ping if you have specified a value for APPLICATION_NAME. Otherwise, the default value is ping. If you specify a custom value for PING_SVC_NAME, this value overrides the default value. If you want to use templates to deploy multiple broker clusters in the same OpenShift project namespace, you must ensure that PING_SVC_NAME has a unique value for each deployment.

VOLUME_CAPACITY

Specifies the size of the persistent storage for database volumes.

Note

If you use broker.xml for a custom configuration, any values specified in that file for the following parameters will override values specified for the same parameters in the your application templates.

  • AMQ_NAME
  • AMQ_ROLE
  • AMQ_CLUSTER_USER
  • AMQ_CLUSTER_PASSWORD

10.3. 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>]>
