我正在用compose file触发mysql：

version: "3"
services:
  my-sql:
    image: mysql
    container_name: my-sql
    ports:
     - 3306:3306
    environment:
     MYSQL_ROOT_PASSWORD: passw0rd 
     MYSQL_USER: dbuser
     MYSQL_PASSWORD: pass1234
     MYSQL_DATABASE: connect_test

按以下方式查找容器的IP地址：

root@sevenos:~# docker inspect my-sql | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "172.18.0.2",

当我与 my-sql client 在容器外，我得到如下错误：

root@sevenos:~# mysql -uroot -ppassw0rd -h 172.18.0.2 -P 3306
mysql: [Warning] Using a password on the command line interface can be insecure.
