RabbitMQ Operator

概述

参考：

• 官方文档，
• https://www.rabbitmq.com/kubernetes/operator/operator-overview.html
• https://www.rabbitmq.com/kubernetes/operator/using-operator.html#override

通过 Operator 部署一套生产可用的 RabbitMQ 集群

创建 namespace

kubectl create ns rabbitmq

部署 operator

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

创建 PV

cat > rabbitmq-pv.yaml << EOF

kubectl apply -f rabbitmq-pv.yaml

部署 RabbitMQ 集群

若使用默认 image ，则镜像中无 python 环境，也无 rabbitmqadmin 工具。

cat > rabbitmq.yaml <<EOF
apiVersion: rabbitmq.com/v1beta1
kind: RabbitmqCluster
metadata:
  name: tj-test
  namespace: rabbitmq
spec:
  rabbitmq:
    additionalPlugins:
    - rabbitmq_delayed_message_exchange
  image: registry.cn-zhangjiakou.aliyuncs.com/ehl_common/rabbitmq:3.8.3-xdelay
  replicas: 3
  service:
    type: NodePort
  override:
    # clientService 再新版crd中变成了 service
    clientService:
      spec:
        ports:
        - name: http
          protocol: TCP
          nodePort: 45672
          port: 15672
        - name: amqp
          protocol: TCP
          nodePort: 35672
          port: 5672

EOF

kubectl apply -f rabbitmq.yaml

创建用户并配置权限

kubectl exec -it -n rabbitmq rabbitmq-tj-test-server-0 -- /bin/bash
rabbitmqctl add_user admin admin && rabbitmqctl set_user_tags admin administrator && rabbitmqctl add_vhost test  && rabbitmqctl set_permissions -p test admin '.*' '.*' '.*' && rabbitmqctl set_permissions -p / admin '.*' '.*' '.*' && exit

测试是否可以创建队列

rabbitmqadmin --vhost=test declare queue name=test-1 queue_type=quorum
