Custom Version and Images
It’s possible to overwrite the default Grafana image in multiple ways.
When applying a new Grafana CR, if .spec.version is absent, the operator will populate the field with the current default.
This prevents unplanned restarts of Grafana instances when the operator is upgraded and the default is updated.
apiVersion: grafana.integreatly.org/v1beta1
kind: Grafana
metadata:
name: versioned
spec:
version: 11.6.0 # grafana/grafana:11.6.0
config:
security:
admin_user: root
admin_password: secret
The .spec.version field supports setting image names allowing the use of private registries or use alternate images.

kind: Grafana

admin_password: secret
Additionally, it’s possible to lock images with sha256 hashes to ensure the same OCI Artifact is retrieved.
