The container's health check only fetched the login page, through nginx and gunicorn. A job worker, novncd or socketiod that kept failing (runit starts it again each second) left the container healthy while jobs waited and consoles failed. The check now also asks runit for each service and fails when one is down or has run for less than five seconds.
