docker网络双向连接详解

查看docker网络

docker network ls

1. [root@master ~]# docker network ls
2. NETWORK ID NAME DRIVER SCOPE
3. e9ecd3b9be87 bridge bridge local
4. 45336895a3a4 host host local
5. 6a44e8330adb none null local

创建网桥

docker network create bridge my-bridge

1. [root@master ~]# docker network create -d bridge my-bridge
2. 0ae59991f86c3276acfc5a78dd316f47c124f093e60ce719046f1045ccccb1bd
3. [root@master ~]# docker network ls
4. NETWORK ID NAME DRIVER SCOPE
5. e9ecd3b9be87 bridge bridge local
6. 45336895a3a4 host host local
7. 0ae59991f86c my-bridge bridge local
8. 6a44e8330adb none null local

将两个容器加入此网桥

1. docker network connect my-bridge centos-test-1
2. docker network connect my-bridge centos-test-2

1. [root@master ~]# docker network connect my-bridge centos-test-1
2. [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

1. [root@master ~]# docker exec -it centos-test-1 bash
2. [root@bd4aa8b35c8d /]# ping centos-test-2
3. PING centos-test-2 (172.18.0.3) 56(84) bytes of data.
4. 64 bytes from centos-test-2.my-bridge (172.18.0.3): icmp_seq=1 ttl=64 time=0.131 ms
5. 64 bytes from centos-test-2.my-bridge (172.18.0.3): icmp_seq=2 ttl=64 time=0.163 ms
6. ^C

9. rtt min/avg/max/mdev = 0.131/0.147/0.163/0.016 ms

1. [root@master ~]# docker exec -it centos-test-2 bash
2. [root@d8eac6105db2 /]# ping centos-test-1
3. PING centos-test-1 (172.18.0.2) 56(84) bytes of data.

7. ^C
