This Docker image has builtin the autocluster plugin and is configured to support a deployment in Kubernetes as a stateful set with persistent volumes attached to the pods.
This ensures a highly available cluster which can recover, in case of a full outage, from persistence.
See the Kubernetes example here.
To start this in your minikube cluster just call kubectl apply -f examples/kubernetes.yml.
This will create a 3 node RabbitMQ cluster with persistence volumes attached to
the storage. So even a StatefulSet scale to 0 the cluster will survive.
The example configures the cluster to stop when a partition detects to be a minority and restarts after a majority is gained. More about this can be found in the RabbitMQ documentation.
This is important to know. Because it is not possible to simply scale down the
StatefulSet from 7 to 3 nodes. You will need to slowly scale down the cluster
and remove down nodes. Otherwise the resulting 3-node cluster will not be the
majority of all defined nodes.
This is image based on rabbitmq:3.6-alpine with the following plugins
enabled: rabbitmq_management, rabbitmq_shovel, rabbitmq_shovel_management, autocluster
