### 查看网络

```
sudo docker network list
```

### 创建一个网络

```
sudo docker network create 网络名称
sudo docker network create net
```

### 实践

1.mysql

```
version: "2"
services:
    mysql:
        image: xxfaxy/3-mysql-server:5.7
        container_name: mysql
        ports:
            - "3306:3306"
        environment:
            - MYSQL_ROOT_PASSWORD=1234
        volumes:
            - /home/php/data/disk/mysql:/var/lib/mysql
        restart: always
        networks:
            - default
networks:
    default:
        external:
            name: net
```

2.phpmyadmin

```
version: "2"
services:
    phpmyadmin:
        image: xxfaxy/self-alpine-phpmyadmin
        container_name: phpmyadmin
        ports:
            - "8000:80"
        environment:
            - HOST_IP=mysql
        external_links:
            - mysql
        restart: always
        networks:
            - default
networks:
    default:
        external:
            name: net
```

如果一个容器(phpmyadmin)需要访问另一个容器(mysql)，可以用`external_links`连接外部容器，并且两者需要加入同一个网络
