Summary Of Changes

Additional Context

Local Testing

Please ensure you run the unit, integration and system tests before approving the PR.

To run the unit and integration tests:

$ make unit-tests integration-tests

You will need to target a k8s cluster and have the operator deployed for running the system tests.

For example, for a Kubernetes context named dev-bunny:

$ kubectx dev-bunny
$ make destroy deploy-dev
# wait for operator to be deployed
$ make system-tests

Hi @chengjoey, thank you for contributing to the cluster operator!

Since the 28th of July 2025, all external contributors to RabbitMQ will have to sign a CLA again [1].

The process is not complicated. Simply send us an email from the address you are committing your work, as described in [2].

Note companies that contribute to RabbitMQ only need to sign the CLA once, there is no need to make every
contributing employee to do so separately.
