Woah... talk about me spinning over the wrong thing! I made so many
adjustments to these files in the past couple days while reading through
docs, blogs and SO that I became rather consumed by the "mod_wsgi (pid=7):
Target WSGI script '/var/www/configurator/apache/backend-dev.wsgi' cannot
be loaded as Python module." error message to the point that I missed the
most obvious part in the end (this was the last of many error messages as
you can imagine). *Thank you! * Now that I've taken a full dose of dufus
for the year, I'll take a moment to rejoice in the fact that I got my first
Docker container to work ;)
Btw, I really enjoyed watching your "Secrets of a WSGI master" youtube
video. I learned a lot and am looking forward to experimenting with
*warpdrive* and updating this docker image so that A) python is in a
virtual environment and B) not run this container as root.
Thanks again Graham. You rock!
