Description

observation

A openqa-worker instance shows a "503 - Service not available" error right after startup.
Here is a screenshot of this: http://10.162.31.103/tests/91#step/worker/7

steps to reproduce

  • Run the "openQA in openQA" test on a not so powerful machine
  • See how the startup of openqa-worker fails with a 503 error

problem

After a short talk to rbrown we came up with the idea that this is maybe an issue with the service file of openqa-(websockets|worker).
Most likely the worker wants to connect to the websockets service which is not available this fast right after bootup.

suggestion

If it is really an issue with the connection between openqa-websockets and openqa-worker, this could easily be fixed by adding openqa-websockets as dependency in the service-file of openqa-worker.

workaround

Obviously this issue does not appear on instances of openqa which are running on more powerful machines (like e.g. o3).
Maybe a sleep before the startup of openqa-worker is a suitable workaround but not tested yet by me.
