创建网桥

docker network create bridge my-bridge

[root@master ~]# docker network create -d bridge my-bridge

将两个容器加入此网桥

docker network connect my-bridge centos-test-1

docker network connect my-bridge centos-test-2

[root@master ~]# docker network connect my-bridge centos-test-1

[root@master ~]# docker network connect my-bridge centos-test-2
容器内可相互通过容器名进行通信

[root@master ~]# docker exec -it centos-test-1 bash

[root@bd4aa8b35c8d /]# ping centos-test-2
