Missing app.kubernetes.io/component Label in Pods Generated by Helm for Grafana

[gvrodrigueznetlabs]

Problem Description:

The Grafana Service is configured with a selector that uses several labels, but the pods generated by Helm for Grafana lack some of the labels required by the Service selector. This mismatch prevents the Service from properly targeting the Grafana pods.

Details:
Grafana Service:
The Grafana Service uses the following selector to match pods:

selector:
app.kubernetes.io/component: grafana
app.kubernetes.io/instance: grafana
app.kubernetes.io/name: grafana

The pods generated by Helm for Grafana currently have the following labels:

labels:
app.kubernetes.io/instance: grafana
app.kubernetes.io/name: grafana
app.kubernetes.io/version: 11.3.1
helm.sh/chart: grafana-8.6.4
pod-template-hash: 57ffb45bd8

The label app.kubernetes.io/component: grafana is missing, which is required for the Service to properly select the pods.
