This is a simple testcase to determine whether docker-storage-setup runs correctly after booting an Atomic Host.

This testcase assumes you have already ran the boot test.


  1. Ensure you have a booted working Atomic Host

How to test

  1. Run the following commands:
# journalctl -o cat --unit docker-storage-setup.service
# docker info

Expected Results

  1. The output of the first command should resemble:
# journalctl -o cat --unit docker-storage-setup.service
