VPN client in a thin Docker container for multiple VPN providers, written in Go, and using OpenVPN or Wireguard, DNS over TLS, with a few proxy servers built-in. - GitHub - qdm12/gluetun: VPN clien...
The container connects to the VPN and only the VPN, now you can route whatever docker containers you want through that container as a network. Now that one VPN connection can serve any container you want.
I use gluetun to route traffic from some of my containers that need a VPN. qBittorrent, Jackett etc. Some containers dont have the option to configure a proxy so you'd have to setup a VPN client within a container which isn't ideal. With gluetun its easy to attach a container to it and it just works
Why isn't it ideal? I'm currently using this setup with containers routed through a gluetun container connected to a vpn via wireguard, and it seems to be working fine. I've verified using curl inside the relevant containers to query an IP checker and I've also used a torrent IP checker to confirm my torrent client isn't leaking my IP.
Also the biggest benefit; You only need 1 VPN connection and 1 key pair for gluetun to connect everything. Most VPN providers limit the amount of active simultaneous connections. If you have lots of containers that need it then it's not possible
