What are the knowledge points of two-way network connection in Docker
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.
