Hello! I have a free account at hide.me and would like to try to use it with my docker compose containers. The free plan does not give me the keys for openVPN of Wireguard configuration, but only through the official client. I’d like then to create a docker container that runs the official hide.me client inside, and exposes it to other docker containers (like gluetun does, for instance). I’d also like to implement a killswitch or something like that to prevent ip leakage. Is this something easy-medium hard or something very complex? I already have a script that installs and runs the client to enable vpn that should be run at startup, but I miss the “expose the network interface” and the “do not expose it if not connected” (this last part I think is pretty easy with a basic firewall configuration)
any tips/something already done?
thanks in advance!
EDIT: probably crazy idea, but would it be possible to do this in gluetun?
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.
