How to build a simple docker Network in DDBMS

This article will explain in detail how to build a simple docker network in DDBMS. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The topology diagram is as follows:

Host1:10.20.10.70

Host2:10.20.10.71

Create an ovs switch on host 1 and host 2, respectively:

Ovs-vsctl add-br ovs0ip link set ovs0 up

Add a port for ovs0 (br0 in the same IP address range):

Ovs-vsctl add-port ovs0 br0

Create a gre tunnel to host2 on host 1:

Ovs-vsctl add-port ovs0 gre0-set interface gre0 type=gre options:remote_ip=10.20.10.71

Create a gre tunnel to host1 on host 2:

Ovs-vsctl add-port ovs0 gre0-set interface gre0 type=gre options:remote_ip=10.20.10.70

Start a container on host 1 (use pipework to hang the container on br0, assigned the ip address of 192.168.2.10):

. / ldocker.sh

Start a container on host 2 (use pipework to hang the container on br0, assigned the ip address of 192.168.2.11):

. / ldocker.sh

Enter the container on host 1 and the container on ping host 2:

You can communicate with ping.

Configuration successful

The ldocker.sh code on host1 is as follows (because of trial and error, the hand is soft, so use a simple script):

#! / bin/shdocker run-itd-- name=test1 hochikong/erbuntu:v1pipework br0 test1 192.168.2.10 docker 24 this is the end of the article on "how to build a simple docker network in DDBMS".
