docker-compose管理容器network与ip问题
作者：binbreaze
这篇文章主要介绍了docker-compose管理容器network与ip问题,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教
docker-compose管理容器时，通常需要设定network，指定容器的ip，这样容器在启动时会通过指定的ip与宿主机桥接网络通信，同样可以通过ip实现容器之间的通信。
新建docker的network桥接网络
docker network create docker1 -o com.docker.network.bridge.name=docker1 -o com.docker.network.bridge.host_binding_ipv4=0.0.0.0 --driver=bridge --subnet=172.20.0.0/16 --gateway=172.20.0.1
- docker1 桥接网卡名称
- subnet 子网掩码
- gateway 网关
查看新建网桥
docker network ls
docker network inspect docker1
