Create an image that provides basic sshd services

1. Use the dockerfile Method

   Preparations

   # Mkdir sshd_ubuntu create a working directory

   # Cd sshd_ubuntu

   # Touch dockerfile run. Sh the file to be copied to the container after being created

   # Vi run. Sh run. SH Content

   #! /Bin/bash

   /Usr/sbin/sshd-d

   # Cat ~ /. Ssh/id_rsa.pub> authorized_keys copy the public key that needs to be logged on to the container Machine

   Write dockerfile

   ------------------------------------

   # Set the inherited Image

   Fromubuntu: 163

   # Provider Information

   Maintainerfrom buranle, test sshd Images

   # Because the image used has been changed to the APT source of 163, no changes will be made here.

   # Install the SSH service

   Runapt-Get install-y openssh-Server

   Run mkdir-P/var/run/sshd

   Run mkdir-P/root/. SSH

   # Remove PAM module restrictions

   Run sed-Ri's/session required pam_loginuid.so/# session required pam_loginuid.so/G'/etc/PAM. d/sshd

   # Copy the file to the response location and grant the script execution permission

   Addauthorized_keys/root/. Ssh/authorized_keys

   Addrun. sh/run. Sh

   Run chmod755/run. Sh

   # Open Port

   Expose 22

   # Set self-starting commands

   CMD ["/run. Sh"]

   ----------------------------------------------

# Dockerbuild-T sshd: dockerfile.

The success text indicates that our image has been successfully generated.

2. Of course we can also use the commit method. We will not introduce it here.

Note: The method of using apt for ease of Source
