我正在尝试从另一个spring启动应用程序容器访问mysql容器，这两个容器位于同一个网络中。我已经创建了一个网络并将两个容器链接到它：

docker network create --driver bridge dmw_network

我的网络详细信息：

            }
        },
        "Options": {},
        "Labels": {}
    }
]

这是我的application.yml文件：

spring:
  application:
    name : ${appName:tasky}
  datasource:
    url: jdbc:mysql://mysql5:3406/dmw_db?autoReconnect=true&useSSL=false
    username: user
    password: pass
    driver-class-name: com.mysql.jdbc.Driver
    tomcat:
      max-active: 50
      max-idle: 50

这就是我运行两个容器的方式：

docker run --name=mysql5 --network=dmw_network -p 3406:3306 -v $(pwd)/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=pass -d dmw_mysql5

docker run --name dmwapp --network=dmw_network -d -p 8888:8888 -p 9999:9999 -v $(pwd)/conf:/home/conf/config/prod dmwimg

但是我仍然无法通过主机名从同一网络中的另一个spring引导容器访问我的数据库。
错误如下：

当我切换到托管docker容器的服务器的ip地址时，它就工作了。例如：

url: jdbc:mysql://184.4.x.x:3406/dmw_db?autoReconnect=true&useSSL=false

我做错什么了？
