Create a custom container

This example creates a simple custom container that contains a python script in the /etc directory.
In this example, we will use a simple container file named test_lxc.tgz. You can download
from the Digi website.
At the command line of a Linux host, we will unpack the file, add a simple python script, and create a
new container file that includes the python script.

Create the custom container file

1. At the command line of a Linux host, unpack the test_lxc.tgz file:
$ tar -xfv test_lxc.tgz
rootfs/
rootfs/usr/
rootfs/etc/
rootfs/etc/group
rootfs/etc/profile
rootfs/etc/passwd
rootfs/tmp/
$
2. Change to the rootfs/etc directory:
$ cd rootfs/etc
$
3. Create a file named test.py with the following contents:
print("Hello world.\n")
4. Change directories to leave the container file structure:
$ cd ../..
5. Change user and group permissions on all files in the container file structure:
$ sudo chown -R 165536 rootfs
$ sudo chgrp -R 165536 rootfs
6. Tar and zip the directory structure to create a new container file:
$ tar -cvf sudo tar -cvf python_lxc.tgz rootfs
