Rotating VPNs #33

Closed voboda closed 3 years ago

voboda commented 3 years ago

I'd like to rotate VPN servers regularly. Any suggestions?

I tried using a client.conf with multiple remotes and remote-random set to choose a random remote on startup, then used pm2 on the host to pkill openvpn (and also restart the dependent containers so they reconnect) on an interval. But that's proving a bit unreliable. Is there a better way?

Thanks!

Found a way using an external cron orchestrator called deck-chores:

Added the deck-chores container to my docker-compose

  officer:
    container_name: officer
    image: funkyfuture/deck-chores:1
    restart: unless-stopped
    environment:
      TIMEZONE: Europe/London
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

And then added these labels to the openvpn container:

   labels:
      deck-chores.rotate-vpn.command: pkill -SIGHUP -x openvpn
      deck-chores.rotate-vpn.interval: 4 minutes

Every 4 minutes, this restarts the openvpn process within the container but leaves the vpn container itself running. When the openvpn process restarts, it rereads the config file. Since remote-random is set to on, it then chooses a new random vpn from the list.

Connectivity is disrupted for a few seconds, but all the connections between the vpn container and its clients stay intact.

Hope this helps anyone trying to do the same.
