I am deploying grafana(6.6.0) in kubernetes cluster(v1.15.2) and now I want to install Pie Chart plugin in grafana. When I am not in docker, I could use this command to install:

grafana-cli plugins install grafana-piechart-panel

But now I am in kubernetes cluster, I could login to the pod and run install command, but when the pod is destroyed and recreated the installing history is lost. What should I do to permanently install plugin in the kubernetes cluster grafana? I have tried to define in yaml like this:

"name": "grafana",
            "image": "grafana/grafana:6.6.0",
            "ports": [
              {
                "name": "http",
                "containerPort": 3000,
                "protocol": "TCP"
              }
            ],
            "env": [
              {
                "name": "GF_INSTALL_PLUGINS",
                "value": "grafana-piechart-panel"
              }
            ],

and not works for me.

In recent versions of Grafana helm chart, plugins list can be passed as list in values.yaml

## Pass the plugins you want installed as a list.
##
plugins: []
  # - digrich-bubblechart-panel
  # - grafana-clock-panel

Use a persistent disk and mount /var/lib/grafana. Plugins are present in /var/lib/grafana/plugins. After containers restarts the data will persist.

Here is what worked for me when deploying Grafana 7.x and plugins with persistent storage.
