How to use it

kubectl apply -f rabbitmq.yaml
kubectl -n default get pods -w

• Apps connect to amqp://admin:<password>@rabbitmq.default:5672. Open the UI with kubectl -n default port-forward svc/rabbitmq 15672:15672.
• For a cluster of several nodes, use the RabbitMQ Cluster Operator instead.

Prefer Docker Compose? See the RabbitMQ Docker Compose version.
