Going through the same hoops here. I got all instances on VPN but using localhost between TA and its dependencies didn't work. When I used the normal IP it did... before it suddenly stops after initializing redis and ES. The log doesn't stay up or spit out an error, it just stops immediately without saying what happened.
Edit:
Here's what I got from running docker start -ai TubeArchivist
And with that I set the following variable:
TA_UWSGI_PORT: 8085 (instead of 8080)
And I can access TubeArchivist from the VPN container.
