[stable/grafana] During upgrade, password changes in secret but not in grafana

[antonincms]

Hello,

Describe the bug
When we upgrade grafana (with helm upgrade --install stable/grafana) the secret changes but if the release is not new, the new password is not taken into account.

Version of Helm and Kubernetes:
Helm : v3.2.0
Kubernetes : Client v1.18.3 Server v1.14.10-gke.36

Which chart:
stable/grafana, chart version 5.3.5

What happened:
The secret that we can retrieve with kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo from the printed message changed, but grafana only accepted the old password...not retrievable anymore.

What you expected to happen:
The password should probably not change during upgrade, so the secret should stay the same.

How to reproduce it (as minimally and precisely as possible):

• Install grafana
• Write down output of kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo, you should be able to connect with it
• Upgrade grafana
• kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo will give you a different result, and the old one is still the valid password.

Best regards, Antonin
