Missing endpoint on grafana

[flenoir]

Hi,

I'm struggling finishing installing kube-prometheus.

I can reach Prometheus and Alertmanager DNS ( respectively prometheus.eolementhe.cloud and alertmanager.eolementhe.cloud) but i get a 503 error when trying to reach grafana.eolementhe.cloud

I did check several things and, when i describe grafana ingress i found that no IP adress is associated

After making some further search on logs, it appear that endpoint is missing on "kube-prometheus-stack-grafana

My values.yaml file seems to be ok to me.

Does someone have an idea ?

# Default values for kube-prometheus-stack.

The helm charts are neither used nor maintained by the prometheus-operator maintainers. Therefore we don't know the setup, so we're unlikely to be able to help you. I recommend creating an issue on the upstream helm charts repo where these helm charts are maintained.
