Docker port mapping is not successful how to solve, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Host 192.168.2.159 maps local port 8088 to container port 8088

Then use the command netstat-tlnp in the container hadoop1 (network interface address is 192.168.2.10) to find that container port 8088 is not mapped to the host successfully.

Okay. Found a simple way.

Port forwarding is used on the host host. As long as the host receives a request from port 8088, it is forwarded to the docker container address 192.168.2.10 8088

Used in the host host

[root@localhost] # ssh-g-L 8099 root@192.168.2.10 192.168.2.10 root@192.168.2.10

-g: in the-L/-R/-D parameter, the remote host is allowed to connect to the established forwarding port. If this parameter is not added, only the local host is allowed to establish a connection.

-L local port: target IP: target port

Port 8088 can be used after forwarding and jump to port 8088 of the container.
