This container solves the problem of containers with no 'VPN' variant. After setting up this container, route your non-VPN Dockers through this one to protect your IP. Or, when you have no other 'VPN' containers.
Or host, for example a game or webserver by using your VPN Provider's IP, if your VPN Provider supports forwarding.
Both WireGuard and OpenVPN are supported.
Check out https://github.com/DyonR/docker-passthroughvpn for setup instructions.
