I'm trying to deploy mongo in Kubernetes, but before I run the mongo itself, it should do some prerequisites in init containers.

This is the list of configMaps

mongo-auth-env       4      16m
mongo-config         1      16m
mongo-config-env     7      16m
mongo-scripts        10     16m

StatefulSet looks like:

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: mongo
  labels:
    component: mongo
spec:
  selector:
    matchLabels:
      component: mongo

After all files/folders are mounted, there is a run.sh script in the scripts directory which should spin things up, but I can't get to that part because the init container is crashing. Is there any other way of doing this, I tried with Jobs but without success. Am I missing something obvious again, because I can see configMaps in the description, but unfortunately can't get logs because Pod is always initializing, and can't exec into the container because of the same reason? I followed some ideas from this repo. Any input would be appreciated.
