查看docker网络

docker network ls

[root@master ~]# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
e9ecd3b9be87        bridge              bridge              local
45336895a3a4        host                host                local
6a44e8330adb        none                null                local

创建网桥

docker network create bridge my-bridge

[root@master ~]# docker network create -d bridge my-bridge
0ae59991f86c3276acfc5a78dd316f47c124f093e60ce719046f1045ccccb1bd
[root@master ~]# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
e9ecd3b9be87        bridge              bridge              local
45336895a3a4        host                host                local
0ae59991f86c        my-bridge           bridge              local
6a44e8330adb        none                null                local

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
