This directory contains examples that demonstrate minimalistic RabbitMQ cluster deployments on Kubernetes with Kubernetes peer discovery. Note: If you want to access the Kubernetes cluster on a different machine then you will want to copy this config onto the machine that wants access to the cluster. The challenges of standing up Kubernetes clusters, maintaining them, networking and storage are moving out of the realm of do-it-yourself.
