RabbitMQ packaged by VMware - Load custom definitions

It is possible to load a RabbitMQ definitions file to configure RabbitMQ. Follow the steps below:

• Store the JSON as a Kubernetes secret, because definitions may contain RabbitMQ credentials. Within the secret's data, choose a key name that corresponds with the desired load definitions filename (such as load_definition.json) and use the JSON object as the value.

  Here is an example of one such secret:

apiVersion: v1
kind: Secret
metadata:
  name: rabbitmq-load-definition
type: Opaque
stringData:
  load_definition.json: |-
    {
      "users": [
        {
          "name": "user",
          "password": "CHANGEME",
          "tags": "administrator"
        }
      ],
      "vhosts": [
        {
          "name": "/"
        }
      ]
    }

• Specify the management.load_definitions property as an extraConfiguration pointing to the load definition file path within the container (for example, /app/load_definition.json) and set the loadDefinition.enable chart parameter to true.

Any load definitions specified become available within the container at /app.

NOTE: Loading a definition will take precedence over any configuration done through Helm values.

If needed, use extraSecrets to let the chart create the secret. With this approach, there is no need to manually create it before deploying a release. These secrets can also be templated to use supplied chart values. Here is an example:

auth:
  password: CHANGEME
extraSecrets:
  load-definition:
    load_definition.json: |
      {
        "users": [
          {
            "name": "{{ .Values.auth.username }}",
            "password": "{{ .Values.auth.password }}",
            "tags": "administrator"
          }
        ],
        "vhosts": [
          {
            "name": "/"
          }
        ]
      }
loadDefinition:
  enabled: true
  existingSecret: load-definition
extraConfiguration: |
  load_definitions = /app/load_definition.json
