Restart container on loss of network connection

[gabrielwhite]

I've had repeated trouble of containers that use NordVPN losing their network connection when the NordVPN connection itself restarts (which seems to happen 1-2 times a day).

Here's a script I made to do a healthcheck every 3 minutes, and restart the container if needed:

# First check that the containers are running

if ! docker ps | grep nordvpn &>/dev/null; then
  echo "NordVPN is not running"
  exit 1
elif ! docker ps | grep othercontainer &>/dev/null; then
  echo "Othercontainer is not running"
  exit 1
fi

# Test if othercontainer has an internet connection. If not, restart the container

if ! docker exec -i othercontainer curl -f -s -I "https://www.google.com/" &>/dev/null && true; then
  docker restart othercontainer
fi

Give it a try to the latest version, it may reconnect but the container should not restart keeping the connection to the others containers alive.

Seems to have fixed the issue thanks! I've seen two reconnects in NordVPN and my checking script hasn't done any restarts.
