This is the Koha Integrated Library System, http://koha-community.org. It's running Koha 3.12 from Koha's Debian repository.
For the most part the install instructions for Ubuntu from the Koha commkunity site were followed. Some extra massaging was done to bring it in line with the Docker way; you can see those in the container at /notes.txt
Start with "docker run jbfink/koha supervisord -n"
