k8s 回调

使用k8s回调函数,部署rabbitmq自动初始化一些操作

apiVersion: v1
kind: Pod
metadata:
  name: lifecycle-demo
spec:
  containers:
  - name: lifecycle-demo-container
    image: nginx
    lifecycle:  # 回调
      postStart: # 容器启动后
        exec:
          # Kubernetes容器管理逻辑会一直阻塞等待 postStart 处理函数执行完毕,延长等待10s,让容器启动完。
          command: ["/bin/sh", "-c", "sleep 10;rabbitmqctl add_user username password;set_user_tags username management;rabbitmqctl add_vhost /vhost1;"]
      #preStop: 容器停止后
      #  exec:
      #    command: ["/bin/sh","-c","nginx -s quit; while killall -0 nginx; do sleep 1; done"]
