# 附录：网络 network

[network官方文档](https://docs.docker.com/engine/reference/commandline/network/#usage)

首先使用`docker network ls`看一下，默认会创建 桥接模式bridge

**比如：**

当你启动了一个没有指定网络的compose，则会建立一个默认的mycompose\_default 的网络。使用下面的命令查看网络详情。

```
docker network inspect mycompose_default
```

当我们启动容器时，默认会加入bridge这个网络。

**示例创建一个简单的网络**

最简单语法

```
docker network create -d bridge mynginx
```

让我们启动容器时就可以加入`docker run-d--network=mynginx 容器名`，这时创建的容器会加入这个网络

设置子网 地址

```
docke rnetwork create -d bridge--subnet=192.128.0.0/16 mynginx
```

`http://tool.chinaz.com/Tools/subnetmask`这里有个子网掩码的计算地址
