I know you can run wireguard containers and then route all the containers that need a VPN through that, but it is something i would need to look up and frankly i cant see the benefits of doing it via docker instead of the system’s wireguard manager.
This is what I do and the biggest benefit is that if anything happens to the VPN container, then qbittorrent loses any ability to connect. Which prevents it from exposing your actual IP. You can setup a kill switch for a system install of wireguard, but I just find this as a more elegant and full prof way of doing it. Plus if you try to use qbittorrent and can’t connect, then you know your VPN is down and you need to look into it.
