How to reset grafana's admin password (installed by helm)

Question

My password once worked, but I don't remember if I changed it or not.

However, I can't reset it.

I tried with no success:

kubectl get secret --namespace default grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo 
> DpveUuOyxNrandompasswordYuB5Fs2cEKKOmG <-- does not work (anymore?)

PS: I did not set any admin email for web-based reset

Answer 1

Ok found. Best way is to run grafana-cli inside grafana's pod.

kubectl exec --namespace default -it $(kubectl get pods --namespace default -l "app=grafana,release=grafana" -o jsonpath="{.items[0].metadata.name}") grafana-cli admin reset-admin-password yourNewPasswordHere
