The only hard dependencies are Redis and Postgres. The official stance is to run them from the provided docket compose and the container for paperless-ngx itself is kept updated and working for the stable containers of redis and postgres.

Tika and Gotenburg are additional features for scanning and converting MS Office documents to PDF. Not necessary and I don't use them in my setup at all. Same with sftpgo. I'm not sure for its usecase. But paperless doesn't directly depend on it in anyway.

Postgres didn't actually a requirement either. Sqlite is supported and default unless you provide configuration for connecting to a database host.

I've used the one click TrueNAS app for a while and it's been solid. I had less luck with the TrueCharts o variant.

Entirely possible the instability was my fault but the error messages didn't make it obvious what was wrong.

It's in this script so I can SFTP PDFs from my scanner over the network. Push button, scan paper and then it is SFTP'ed to a shared volume between SFTPGo and Paperless so it is detected and ingested into Paperless NGX automatically.

Even if you use :latest it doesn't update by itself.
