Docker容器配置固定IP

1.使用默认网络进行固定IP地址创建时会报错

# docker run -d --name jenkins -p 8082:8080 --restart=on-failure -v /data/jenkins:/root/.jenkins --network bridge --ip 172.17.0.5 tomcat7:base
9c018e499555e46a942e4c21bdf2647a04d701896ce9eeb53f53b8d94ee6b776
docker: Error response from daemon: user specified IP address is supported on user defined networks only.

2.根据报错提示，只有在自定义网络下才可设置固定IP，故:

# docker network create --subnet 172.18.0.0/16 mynetwork

# docker run -d --name jenkins -p 8082:8080 --restart=on-failure -v /data/jenkins:/root/.jenkins --network mynetwork --ip 172.18.0.2 tomcat7:base
