Feature: Allow to mount custom volume for data #798
Description
Description of the change
Right now helm chart only allows mounting datadir as subPath of nextcloud-main PVC. We can see this in deployment template:
{{- if and .Values.persistence.nextcloudData.enabled .Values.persistence.enabled }} - name: nextcloud-data mountPath: {{ .Values.nextcloud.datadir }} subPath: {{ ternary "data" (printf "%s/data" .Values.persistence.nextcloudData.subPath) (empty .Values.persistence.nextcloudData.subPath) }} {{- else }} - name: nextcloud-main mountPath: {{ .Values.nextcloud.datadir }} subPath: {{ ternary "data" (printf "%s/data" .Values.persistence.subPath) (empty .Values.persistence.subPath) }} {{- end }}
My problem is that my data is stored under hostPath (4Tb volume). Moving it to PVC is problematic because CSI driver has a different underlying storage.
Suggestion - allow mounting datadir from one of extraVolumes.
Benefits
Adds more flexibility to the chart by adding another storage management option.
Possible drawbacks
Maybe add a little more complexity in values but seems that chart structure is already complex enough so that wont affect it much.
Additional information
Thanks in advance for considering change :)
