默认的bridge网络不支持指定IP地址
```
# docker run -itd --net bridge --ip 172.17.0.10 centos:latest /bin/bash

docker: Error response from daemon: User specified IP address is supported on user defined networks only.
```

docker network create --subnet=172.18.0.0 /16 mynetwork
```
查看网络
```
docker network list
```
指定ip
