Each container, by default, runs in a separate network namespace. You can use docker CLI to create specific networks that can be shared with other containers, or use docker-compose for it. Technically, for processes outside containers you can still use the same network of that container by running the inside the network namespace of the 'VPN' container (for example running them with unshare). However, I wouldn't recommend this, as containers are supposed to run mostly isolated workload and not for this kind of use-case. But yeah, technically it's feasible.

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.

It sounds like you want Qubes
isn't it an entire OS? I only need to bind the internet traffic of my container to the ones I want doing something like network_mode: container:myhidemecontainer in docker compose
I think something like gluetun is more suited than a whole OS.
But i don't know the specifics of hide.me
Hide.me free tier does not allow unofficial clients (they doesn't give you the wireguard keys) otherwise I'd use gluetun for sure!
Fair enough. I got confused by their FAQ. They say Wireguard is supported on their free plan. But there is no config available with the keys, so you have to use their client to connect.
I recently registered an account and wanted to do something similar. Guess it isn't that easy then. Another possibility is to use protonvpn.com they also offer a free tier and you can connect any Wireguard client with that.
Or you switch protocols and use for example IKEv2 with strongswan or OpenVPN or whatever hide.me offers in addition to wireguard. I think gluetun also does OpenVPN. But hide.me isn't listed for some reason.
I used to use proton vpn but I recently learned that torrenting is not allowed on the free tier, so I had to look for alternatives, and none of them offers a free tier with openvpn or wireguard keys that allows torrenting :(
Ah, well I just learned about the existence of free vpn services. I'm going to use it to set up a free guest wifi, so the neighbors, guests (and I) can do whatever with it. But I also struggle with the setup. It's complicated to get the wireguard interface set up, the guest wifi isolated and set up the split routing and everything so the different wifis on the router forward the traffic over different services.
The risk if human error is too high. Docker isn't designed for security. What you want is Qubes. Its destined to do these things.
Have you had a look at binhex’s privoxyvpn docker container? Sounds similar to what you’re looking to do.
I'll look into it, thanks!
Idk anything about those softwares, but I would bet if you set up the hide.me client in a container you could add it to the same network in compose then configure all the other containers to use it as their gateway... I'm probably missing some details and you may need to rebuild all of your containers, or maybe just change the network settings in your compose yaml?
What are you running your containers on? I just put my VPN on the docker host so I could be sure I could use the firewall to block traffic from going out except over the VPN.
