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.

1. At the command line of a Linux host, unpack the test_lxc.tgz file:

$ tar -xfv test_lxc.tgz

rootfs/etc/group

rootfs/etc/profile

rootfs/etc/passwd

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:

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:

$ sudo tar -czvf python_lxc.tgz rootfs

If using macOS, include the --disable-copyfile option with this command:

$ sudo tar --disable-copyfile -czvf python_lxc.tgz rootfs
