@Zerpet can you tell why Helm was deleted? Should I use kubectl plugin instead?

[Zerpet]

@kvendingoldo the main reason was adoption. Since we didn't publish this chart to Helm Hub, and it was used mostly within our team, we believe this chart was not used at all. I use the kubectl plugin nowadays to deploy RabbitmqCluster objects.

@Zerpet that's unfortunate. Helm is much better when used with GitOps to manage version upgrades (And GitOps is gaining in popularity).

There is a helm chart over @bitnami but nothing beats an officially maintained chart and there are easy ways to publish it

[MarcialRosales]

@politician bitnami cluster-operator helm chart is an officially maintained chart. It is been actively maintained and tested against latest RabbitMQ kubernetes cluster-operator by bitnami team.

@MarcialRosales Ok I didn't know it was considered as the official chart. Maybe the official documentation should reflect that? I must say, I am always looking for the Helm install instructions because I know my life will be easier for my workflow (GitOps) and am sure many others are in the same boat.

[MarcialRosales]

@politician You are absolutely right. Thanks for the suggestion. We will make sure that our official documentation reflects it as it is the first point of contact to the product. Thanks!
