Docker Cookbook - Second Edition

How to do it...

Perform the following steps:

1. Create the directory on which you want to populate all the distribution files:

        $ mkdir xenial 

2. Now, using debootstrap, install Xenial Xerus inside the directory we created earlier:

        $ sudo debootstrap xenial ./xenial 

You will see the directory tree, similar to any Linux root filesystem, inside the directory in which Xenial Xerus is installed:

        $ ls ./xenial
        bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc       root  run  sbin  srv  sys  tmp  usr  var 

3. Now, we can export the directory as a Docker image with following command:

        $ sudo tar -C xenial/ -c . | docker image import - xenial  

4. Look at the docker image ls output. You should have a new image with xenial as the name.
