Support of priorityClassName

[timbrd]

My k8s cluster is running several RabbitMQ clusters - a production and 3 development clusters.
I would like to define a priority class for my RabbitMQ pods to prioritise the production cluster when resources are low.

In the operator documentation I could not find a way to set a priority class, so I guess it is currently unsupported?

You should be able to set priorityClassName through .spec.override.statefulSet: https://www.rabbitmq.com/kubernetes/operator/using-operator.html#override

Thanks, overriding the container part of the statefulset worked.

Would there be any chance to share an example for posterity?

This snippet works for me:

override:
  statefulSet:
    spec:
      template:
        spec:
          priorityClassName: "your-priority-class"
          containers:
            - name: rabbitmq

Keep in mind that containers: field is required when you override .statefulSet.spec.template.spec block
