I am trying to install grafana using helm, during the installation I see the error in the init container
kc logs monitoring-gr-grafana-7f9cd58674-5jnkq -c download-dashboards mkdir: can't create directory '/var/lib/grafana/dashboards/': Permission denied

Hi,

Did you follow the guidelines and sample for Grafana Helm repo ?

I suggest you take a look at it :

github.com

grafana/helm-charts/blob/main/charts/grafana/values.yaml

global:
  # -- Overrides the Docker registry globally for all images
  imageRegistry: null

  # To help compatibility with other charts which use global.imagePullSecrets.
  # Allow either an array of {name: pullSecret} maps (k8s-style), or an array of strings (more common helm-style).
  # Can be tempalted.
  # global:
  #   imagePullSecrets:
  #   - name: pullSecret1
  #   - name: pullSecret2
  # or
  # global:
  #   imagePullSecrets:
  #   - pullSecret1
  #   - pullSecret2
  imagePullSecrets: []

rbac:
  create: true

Hope it helps.

Good Luck

Problem with the permission is caused by helm-charts/_pod.tpl at 9662c19aa193797d5349b88e533dfc6f210039a5 · grafana/helm-charts · GitHub

basically grafana chart has this

args: [ "-c", "mkdir -p /var/lib/grafana/dashboards/default && /bin/sh /etc/grafana/download_dashboards.sh" ]

and when the init container try to create directory there is permission issue

mkdir: can't create directory '/var/lib/grafana/dashboards/': Permission denied

Not sure what is the solution to solve this issue
