erlang cookie创建

echo $(openssl rand -base64 32) > erlang.cookie
kubectl -n $namespace create secret generic erlang.cookie --from-file=erlang.cookie
kubectl -n $namespace create -f manifestos/rabbitmq-service.yaml

运行

kubectl -n $namespace create -f manifestos/rabbitmq-deploy.yaml

检查群集状态

FIRST_POD=$(kubectl get pods -n $namespace -l 'app=rabbitmq' -o jsonpath='{.items[0].metadata.name }')
kubectl -n $namespace exec -ti $FIRST_POD rabbitmqctl cluster_status
