This article mainly explains "what is the method of Docker port mapping and container interconnection". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the method of Docker port mapping and container interconnection".

A new mydocker container is established, in which a mysql is installed and started. It is hoped that the container's mysql database can be accessed directly through centos.

Method one

[root@mysql01 ~] # docker inspect mydocker | grep-I ipaddre

"SecondaryIPAddresses": null

"IPAddress": "172.17.0.3"

"IPAddress": "172.17.0.3"

Configure forwarding:

[root@mysql01] # iptables-t nat-A DOCKER-p tcp-- dport 3388-j DNAT-- to-destination 172.17.0.3

Check:

[root@mysql01 ~] # docker port mydocker

[root@mysql01 ~] # netstat-nputl | grep-I 3388

[root@mysql01 ~] iptables-t nat-L-n (Port forwarding can be viewed in this way)

Method 2:

1. Save the mydocker container as a mirror first

Docker commit mydocker myimages

two。 Then restart a container mysql5.6.24 on the myimages image and specify the port mapping

Docker run-d-name mysql5.6.24-p 3366 it myimages 3306-it myimages / bin/bash

3. Check

[root@mysql01 ~] # netstat-nputl | grep-I 3366

Tcp6 0 0: 3366: * LISTEN 17673

[root@mysql01 ~] # docker port mysql5.6.24

3306/tcp-> 0.0.0.0pur3366
