App is crashing in k8s setup

[organismen]

Im struggeling with getting nodebb to run in kubernetes cluster. I was very glad to find your project but sadly I'm not getting it to work at the moment. I was hoping if you could give some suggestions where to look next.

I've setup a deployment with persistant storage (GKE). when I deploy it crashes with nothing special in the log, see image below. Its hard to see exactly where it loops but it seems to be after the first mongo error.

I've managed to get it to work with the provided docker-compose file, everything starting up OK.

Reviewing the log, it seems that the next log output after my crashpoint above is:

nodebb_1   | No categories found, populating instance with default categories

Is that clue?
