This gist stays put so the comments below remain readable — there is a lot of useful troubleshooting in them. For corrections, please open a PR or issue on the repo.

Description

This template runs watchtower. This is new for me so still seeing if i like it! (fingers cross this works, yes need to setuyp smtp email at some point, lol)

State Considerations for SWARM

none, this container can be cofigured entirely by env vars so i use those

Network Considerations

none, no published port is needed

Placement Considerations

None, by default this template will result in a single replica.
