From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can I use a docker container to route only 1 program through a VPN? (self.linux)

I am running Ubuntu Server with Plex, qBittorrent-Nox, and CyberGhost. I want to route qBittorrent through the CyberGhost VPN, but not Plex.

I have never used Docker, but from what I gather online, it seems like the containers operate like little VM’s for compartmentalization and resource allocation. If that is correct, would I be able to put qBittorrent-Nox and CyberGhost into the same docker container to route qBittorrent-Nox through the VPN while Plex runs outside the VPN in its own snap?

Thanks for the help!

Never heard of CyberGhost before. Does its Linux client not support split tunneling? Many VPN clients do, which lets you route only certain programs though them.

A Docker container seems like overkill, it can be accomplished with a network namespace. There is a bit written about it here: https://volatilesystems.org/wireguard-in-a-separate-linux-network-namespace.html, though that doesn't include how to set up the Wireguard config (which depends on the VPN).
