Hi selfhosted, I made a short tutorial for anyone who might want to dive into arr selfhosted software but dont know where to start. I did it on my RPI but docker config will work in any docker friendly environment so adjust it to your scenerio. I will gladly discuss that topic so fell free to talk.
I use this guy https://github.com/haugene/docker-transmission-openvpn
Open up the transmission rpc port and you’re golden. It also sets up a proxy for any other services/devices you want to run through the VPN. Supports port forwarding for PIA too.
