How does Docker start a Centos image?

Most people do not understand the knowledge points of this article "how Docker starts a Centos image", so the editor summarizes the following contents, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how Docker starts a Centos image" article.

After downloading a centos image, start starting

# run the command

Docker run-d-I-t / bin/bash

In this way, you can start a centos that has been running in the background. If / bin/bash is missing, docker will generate a container but will stop immediately and will not run consistently even with the-d argument.

Then we can enter our centos.

Docker attach

After entering centos, I found that there were no ifconfig and ssh. Many online examples refer to them.

Installation of ifconfig, execute command

Yum search ifconfig

two。 Install ifconfig

Yum install net-tools.x86_64

Well, with it, you can finally know your own ip and network. Now we still need a ssh so that we can easily access centos.

Then all you have to do is start it.

/ usr/sbin/sshd-d

Then there is the common command to map the port to the host, and here I am the linux system assigned by vm.

# exit, but do not stop container ctrl+p+q# returning to docker, stop container docker stop # submit current container to mirror docker commit # start new container, and do port mapping docker run-itd-p 50001docker stop 22 / bin/bash

All right, so we can access the container by using the ssh tool to access the ip port of the host under windows.

Here I am, 192.168.99.100VR 50001.
