The reason is that the default network mode Docker, by mapping IP + port of the host, and can not find node02 node01 and node03
-
-
Find ip of each container
docker inspect 容器ID- node01: 172.17.0.2
- node02: 172.17.0.3
- node03: 172.17.0.4
-
We know that it has its own IP, it appeared another problem is that it's ip is dynamic, we can not know before you start. There is a solution is to create your own network bridge, and then create the container when the specified ip.
-
So above all to reinvent the wheel ......
-
Stop and delete all mirrors
docker stop $(docker ps -a -q) docker rm $(docker ps -a -q)
[Restart]
-
Create your own bridged network
docker network create --driver bridge --subnet=172.18.0.0/16 --gateway=172.18.0.1 zoonet -
