RabbitMQ Cluster Kubernetes Operator

RabbitMQ Cluster Kubernetes Operator

Kubernetes operator to deploy and manage RabbitMQ clusters. This repository contains a custom controller and custom resource definition (CRD) designed for the lifecycle (creation, upgrade, graceful shutdown) of a RabbitMQ cluster.

Quickstart

If you have a running Kubernetes cluster and kubectl configured to access it, run the following command to install the operator:

kubectl apply -f https://github.com/rabbitmq/cluster-operator/releases/latest/download/cluster-operator.yml

Then you can deploy a RabbitMQ cluster:

kubectl apply -f https://raw.githubusercontent.com/rabbitmq/cluster-operator/main/docs/examples/hello-world/rabbitmq.yaml

Documentation

RabbitMQ Cluster Kubernetes Operator is covered by several guides:

• Operator overview
• Deploying an operator
• Deploying a RabbitMQ cluster
• Monitoring the cluster
• Troubleshooting operator deployments

In addition, a number of examples can be found in this repository.

The doc guides are open source. The source can be found in the RabbitMQ website repository under site/kubernetes.

Supported Versions

The operator deploys RabbitMQ 3.12.2 by default, and supports versions from 3.9.9 upwards. The operator requires Kubernetes 1.19 or newer.

Versioning

RabbitMQ Cluster Kubernetes Operator follows non-strict semver.

The versioning guidelines document contains guidelines on how we implement non-strict semver. The version number MAY or MAY NOT follow the semver rules. Hence, we highly recommend to read the release notes to understand the changes and their potential impact for any release.
