Question

我正在尝试通过服务将phpmyadmin pod连接到mysql pod。

我的环境参数如下。当我把IP地址改为“ mysql-service”与mysql的连接时。但是，IP地址在重新启动Pod之后始终会更改。我正在尝试通过服务

连接phpmyadmin pod

kubectl get svc

        - name: PMA_USER
          value: "root"
        - name: PMA_PASSWORD
          value: "password"
        - name: PMA_HOST
          value: "mysql-service" #<<<---- mysql service
        - name: PMA_PORT
          value: "3306"

请帮助我，请通过服务而非IP连接phpmyadmin。
