Hi Brian,
I had some 500 internal server errors when deploying, especially with loading articles.

Turns out, the uwsgi processes were not connecting with redis.
So I swapped in geerlingguys role for redis instead of sbaerlochers, which is archived since some time and this resolved my issue.
If you can confirm this behavior with your workflow, I can open a pull request, if you like.

Regards,
Dan

PS: the latest fixes for import-articles should also be adjusted in the docker entrypoint scripts.
:)
