Docker creates containers and mirrors that support SSH services

Docker creates containers and mirrors that support SSH services

1. Use CentOS as a container here, so first download CentOS images

   Sudo docker pull CentOS

2. Download and run a CentOS container, Here I use CENTOS6 as my Test Container

   Sudo docker run--name=centos-ssh-i-T centos:centos6/bin/bash

3. Install the Openssh-server service package

   Yum install openssh-server

4. Edit sshd configuration file/etc/ssh/sshd_config, Set the Usepam parameter to "no"

5. Start the sshd service

   /etc/init.d/sshd start

6. Add test user admin, password admin

   Useradd Admin

   Echo ' admin:admin ' | chpasswd

7. In order for the newly added user to run the sudo command, it is necessary to install the sudo package and add the admin to sudoers

   Yum install sudo <--install sudo package

   Visudo < ---Edit sudoers, add the following line to the file

   Admin all= (All) all

8. Test, after the above work, use ifconfig to view the container's IP, or use the sudo docker Inspect "View, then you can access the newly created Docker container via SSH [email protected]<ip> on the host machine.

9. If you want to make the container that supports the SSH service as a Docker image, first exit the container, and then use the following command to create the

   sudo docker commit <container id> <image name>
