I have Grafana deployed on a GKE instance using the grafana.yaml defined here. GKE seemingly has unavoidable automated maintenance that causes the Grafana deployment to be restarted after a certain amount of time. Due to the PVC mounted to the Grafana instance, I assumed that any dashboards I created would be persisted across the deployment restart. However, it seems like this isn’t the case as after each restart, all my data and dashboards are lost. Has anyone else run into this issue?
