I avoided containers for a long time, too. But they truly are game changing.

Is this a server or your pc? Docker is kinda silly if it’s just your pc.

This is what I use as well, although it was primarily out of laziness. Works well enough. I would say the Gluetun solution is a better recommendation, more robust and scalable, but the haugene container basically just works.

I would rather recommend gluetun, it supports multiple VPN protocols and you can attach any container to it
