Hello Graham, et al.
First, thank you for being an outstanding contributor to the community.
This is my first attempt to set up a VM for a pretty old legacy project,
and I am very new to devops in general, so thank you in advance for your
patience! I'm working to move an old Django/Apache project off of Vagrant
into Docker containers. I was able to get it working when using Python's
built-in runserver, but I've been stuck for far too long now trying to get
it to work with Apache. From what I can tell from the docs, etc it seems
that my mod-wsgi version is struggling with Django 1.7 (I'm making a case
with management to upgrade, but so far it's not in the budget). I also
think that I'm incorrectly setting my paths, but my multiple attempts to
correct this have come up empty. Needless to say, there's where I am now.
I'm running docker on a Mac os Sierra Version 10.12.6

This set up gives me a 500 Internal Server error after the container is
built and up. When I investigate the containers Apache error.log file I
get the following output:
