Generate a Docker image using Fabric

Overview

Let's create a Docker image using Fabric. Since Fabric can only be operated via SSH, it is necessary to operate Docker via SSH.

First, define a function docker that performs the following processing.

import atexit
import time
from fabric.api import *
from fabric.contrib.console import confirm


@task
def docker():
    env.hosts = ['127.0.0.1:2222']
    env.user = 'root'
    env.password = 'PASSWORD'

    import docker
    cl = docker.Client()
    container = cl.create_container('BASE_IMAGE_NAME',
                                    command='/usr/sbin/sshd -D',
                                    ports=[22])

    cl.start(container, port_bindings={22:2222})
    time.sleep(3)

    @atexit.register
    def commit():
        cl.stop(container)
        if confirm('Commit container changes?', default=True):
            cl.commit(container['Id'], repository='IMAGE_NAME', tag='TAG')

By writing the following in fabfile.py,

$ fab docker TASK_NAME

It will be possible to execute like.

Also, if you automate and execute docker push etc. in the above commit function, you can automate everything from task execution to Docker Index upload.

In addition, docker-py is required for execution.
