InitScripts can't execute when running as nonRootUser

[cbuffett]

The statefulset mounts the initScripts into the docker-entrypoint-initdb.d/ as being only executable by root. This prevents the script from executing when Influx is being run as a nonRootUser

helm-charts/charts/influxdb2/templates/statefulset.yaml

Lines 38 to 42 in d23ecc4

	{{- if .Values.initScripts.enabled }}
	- name: init
	configMap:
	name: {{ include "influxdb.fullname" . }}-init
	defaultMode: 0744

I was able to fix this using a kustomize patch that sets the defaultMode to 0755

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: influxdb-influxdb2
spec:
  template:
    spec:
      volumes:
        - name: init
          configMap:
            name: influxdb-influxdb2-init
            defaultMode: 0755
