Docker create containers and mirrors that support SSH services

Original link: Docker create containers and mirrors to support SSH services

1. The CentOS used here as a container, so first download the CentOS images

# sudo docker pull CentOS

2. After downloading run a CentOS container, here use CENTOS6 as my Test Container

# sudo docker run--name=centos-ssh-i-T Centos:centos6/bin/bash

3. Install Openssh-server Service Package

# yum Install Openssh-server

4. Edit the sshd profile/etc/ssh/sshd_config, and set the Usepam parameter to "no"

5. Start sshd Service

#/etc/init.d/sshd Start

6. Add test user admin, Password admin

# useradd Admin
# echo ' admin:admin ' | chpasswd

7. To enable the newly added user to run sudo command, you need to install the Sudo software package and add admin to sudoers

# yum Install sudo    <--install sudo package
# visudo              <--Edit sudoers, add the following line to file
 
admin   all= (All)       

8. Test, after the above work, use ifconfig to view the container's IP, or use the "sudo docker inspect" view, and then on the host machine through the SSH admin@<ip> to access the newly created Docker container.

9. If you want to have a good, SSH-enabled container as a Docker mirror, exit the container, and then use the following command to create the

# sudo docker commit <container id> <image name>
