Healthcheck in NordVPN container

[flipyou]

I have several containers which depend on the NordVPN container to have a successful connection and the network all set up. If they start too quickly sometimes I have to restart them after NordVPN is running. This means that on a reboot I can't rely on all my containers simply working.

Could you include code in the container for a Healthcheck? This would allow me to use Healthcheck code in my docker-compose file to stop containers if the VPN is dropped or not not yet ready, and to restart containers when the VPN is up again.

I considered writing a bunch of scripts to start and stop various containers at the right times, but incorporating Healthcheck would be much simpler.

here's a link to the documentation https://docs.docker.com/engine/reference/builder/#healthcheck

The image used to have the helthcheck i removed because is actually checking if the connection is up and not necessarily if the service is up, there's a small diff there. i haven't find a proper healthcheck that i like.

Anyway you can manually add one thought command line or docker-compose to fulfill your needs

please consider creating merge request with a heatlcheck if you find one generic enough, thanks!

also.. is just setup using docker-compose?
if so i believe the dependent components will wait until the nordvpn container is up and ready

FYI - this is the healthcheck I use in my docker-compose, it just checks if the tunnel is up; better than nothing I suppose.

    healthcheck:
      test: "ifconfig | grep ^tun0 > /dev/null"
      interval: 15s
      timeout: 1s
