ppngx: Podman + Paperless-ngx

This is a quick script for setting up Paperless-ngx with Rootless Podman inside a Podman Pod.

It will launch Redis, PostgreSQL, Tika, Gotenberg, SFTPGo and Paperless-ngx inside a self-contained pod. I was able to get this working with Brother ADS2800w and SFTP to SFTPGo. Good luck!

If you want to have a VM runs Paperless-ngx, check out my other project which can be used to run everything on Fedora CoreOS.

Setup

Ensure jq and podman packages are installed (ex dnf install jq podman)
Clone this repository
cd ppngx

Edit start.sh and customize at least these variables:

PAPERLESS_TIME_ZONE=America/Chicago
PAPERLESS_OCR_LANGUAGE=eng
SFTPGO_ADMIN_PASSWORD=supersecret
SFTPGO_PAPERLESS_PASSWORD=anothersupersecret
PAPERLESS_SECRET_KEY=chamgemechamgemechamgemechamgemechamgemechamgemechamgemechamgeme
POSTGRESQL_PASSWORD=paperlesschangeme

Run ./start.sh
Wait a bit and make sure http://localhost:8000 is loading paperless.

Add a superuser to paperless-ngx with:

podman exec -it paperless-webserver python manage.py createsuperuser

If you are going to send documents via SFTP use the scanner and password set in SFTPGO_PAPERLESS_PASSWORD. Some scanners need the RSA Public key from SFTPGo. It is output by the script and written out to a file ${PWD}/sftp_rsa_host_key.pub. Also, most scanners are using older versions of OpenSSH so you might need to adjust SFTPGO_SFTPD__KEX_ALGORITHMS and SFTPGO_SFTPD__HOST_KEY_ALGORITHMS to match the right key algorithms so they can connect as clients to SFTPGo. For example my Brother ADS2800w need the following set to work with the latest version of SFTPGo (v2.5.4).
```
SFTPGO_SFTPD__KEX_ALGORITHMS=curve25519-sha256,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group14-sha256,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
SFTPGO_SFTPD__HOST_KEY_ALGORITHMS=rsa-sha2-256,rsa-sha2-512,ecdsa-sha2-nistp256,ssh-ed25519,ssh-rsa
```

Updating

The most straightforward methodology is to pull the latest image you care about and re-run start.sh. For example:

  podman pull ghcr.io/paperless-ngx/paperless-ngx:latest
  ./start.sh

This will pull the latest image, and assuming your PAPERLESS_VERSION specified in start.sh is latest, will rebuild the pod with the latest versions.

Autostart with systemd

Rootless Podman The script by default assumes you are going to run this as a rootless user. Run loginctl enable-linger $USER so the systemd user instance can be started at boot and kept running even after the user logs out.

Make sure Paperless-ngx is running via start.sh
If it doesn't already exist: mkdir -p ${HOME}/.config/systemd/user
cd ${HOME}/.config/systemd/user
podman generate systemd --new --files --container-prefix='' --name paperless
systemctl daemon-reload --user
podman pod stop paperless
podman pod rm paperless
systemctl enable --user --now pod-paperless.service

Rootfull Podman If you want to run this via systemd as the root user, remove USERMAP_GUID and USERMAP_GID env vars from paperless-webserver before you run start.sh. You will also want to run this script as the root user.

Make sure Paperless-ngx is running via start.sh
cd /etc/systemd/system
podman generate systemd --new --files --container-prefix='' --name paperless
systemctl daemon-reload
podman pod stop paperless
podman pod rm paperless
systemctl enable --now pod-paperless.service

Making changes to your units

Note: If you make changes to start.sh after generating the systemd units you will need to do the following to update the units:

Make your changes to start.sh
systemctl stop --user pod-paperless.service
Make sure Paperless-ngx is running via start.sh
cd ${HOME}/.config/systemd/user
rm -rf paperless-* pod-paperless.service
podman generate systemd --new --files --container-prefix='' --name paperless
systemctl daemon-reload --user
podman pod stop paperless (stops paperless that was started by start.sh)
podman pod rm paperless (removes the paperless pod created by start.sh)
systemctl enable --user --now pod-paperless.service

Or you can edit the systemd unit files directly with your changes and run systemctl daemon-reload --user and then run systemctl restart --user pod-paperless.service.

Backing up

backup.sh is an example generic backup script that will export the required pod volumes, and store the paperless version number. You might want to also backup your modified start.sh as well.

This can either be ran manually as desired or (ideally), as a cron job/whatever.
