This article mainly shows you "what are the knowledge points of two-way network connection in Docker". The content is simple and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "what are the knowledge points of network two-way connection in Docker".

View the docker network

Docker network ls [root@master ~] # docker network lsNETWORK ID NAME DRIVER SCOPEe9ecd3b9be87 bridge bridge local45336895a3a4 host host local6a44e8330adb none null local

Create a bridge

Docker network create bridge my-bridge [root@master ~] # docker network create-d bridge my-bridge0ae59991f86c3276acfc5a78dd316f47c124f093e60ce719046f1045ccccb1bd [root@master ~] # docker network lsNETWORK ID NAME DRIVER SCOPEe9ecd3b9be87 bridge bridge local45336895a3a4 host host local0ae59991f86c my-bridge bridge local6a44e8330adb none null local

Add two containers to this bridge

Docker network connect my-bridge centos-test-1docker 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

The container can communicate with each other through the container name.

[root@master] # docker exec-it centos-test-1 bash [root@bd4aa8b35c8d /] # ping centos-test-2PING centos-test-2 (172.18.0.3) 56 (84) bytes of data.64 bytes from centos-test-2.my-bridge (172.18.0.3): icmp_seq=1 ttl=64 time=0.131 ms64 bytes from centos-test-2.my-bridge (172.18.0.3): icmp_seq=2 ttl=64 time=0.163 Ms ^ C-centos-test-2 ping statistics-2 packets transmitted, 2 received 0% packet loss Time 999msrtt min/avg/max/mdev = 0.131bytes of data.64 bytes from centos-test-1.my-bridge 0.147 + 0.163 * * ms [root@master ~] # docker exec-it centos-test-2 bash [root@d8eac6105db2 /] # ping centos-test-1PING centos-test-1 (172.18.0.2) 56 (84) bytes of data.64 bytes from centos-test-1.my-bridge (172.18.0.2): icmp_seq=1 ttl=64 time=0.187 ms64 bytes from centos-test-1.my-bridge ( 172.18.0.2): icmp_seq=2 ttl=64 time=0.405 ms64 bytes from centos-test-1.my-bridge (172.18.0.2): icmp_seq=3 ttl=64 time=0.150 Ms ^ C-centos-test-1 ping statistics-3 packets transmitted 3 received, 0 packet loss Time 4msrtt min/avg/max/mdev = 0.150 ms 0.247 ms [root@master ~] # docker exec-it centos-test-2 bash [root@d8eac6105db2 /] # ping centos-test-1PING centos-test-1 (172.18.0.2) 56 (84) bytes of data.64 bytes from centos-test-1.my-bridge (172.18.0.2): icmp_seq=1 ttl=64 time=0.187 ms64 bytes from centos-test-1.my-bridge ( 172.18.0.2): icmp_seq=2 ttl=64 time=0.405 ms64 bytes from centos-test-1.my-bridge (172.18.0.2): icmp_seq=3 ttl=64 time=0.150 Ms ^ C-centos-test-1 ping statistics-3 packets transmitted 3 received, 0% packet loss, time 4msrtt min/avg/max/mdev = 0.150, 0.247, 0.405, ms and above are all the contents of the article "what are the knowledge points of two-way network connection in Docker?"
