Unable to modify helm chart of kube-prometheus-stack

[srikanthankam]

Hello Everyone, a need a quick help. I installed kube-prometheus-stack using helm chart with the following command. Note: I didn't use values.yaml file for installation, means chose default configuration.

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts -n monitoring helm repo update helm install prometheus prometheus-community/kube-prometheus-stack -n monitoring

By default, retention=10d is set. I also removed emptyDir configuration in Promethues-Grafana deployment and added 3 EFS volumes.

volumes: - configMap: defaultMode: 420 name: prometheus-grafana name: config - name: storage persistentVolumeClaim: claimName: storage - name: sc-dashboard-volume persistentVolumeClaim: claimName: sc-dashboard-volume - configMap: defaultMode: 420 name: prometheus-grafana-config-dashboards name: sc-dashboard-provider - name: sc-datasources-volume persistentVolumeClaim: claimName: sc-datasources-volume

My requirement is I want to modify only one value in the installed helm chart without affecting other values, like added persistentVolumeClaims in Grafana deployment. Want to change the value from "retention=10d" to "retention=30d". Please help me in this scenario

Hello, When I perform helm install on the latest version of the chart https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack

helm install --dry-run prometheus prometheus-community/kube-prometheus-stack -n monitoring

I see following error

Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: [unable to recognize "": no matches for kind "Alertmanager" in version "monitoring.coreos.com/v1", unable to recognize "": no matches for kind "Prometheus" in version "monitoring.coreos.com/v1", unable to recognize "": no matches for kind "PrometheusRule" in version "monitoring.coreos.com/v1", unable to recognize "": no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"]

Any input why installation is failing thank you.

@vyom-soft is it first time you are trying to install in this cluster, because sometimes there are manual steps to be followed to uninstall kube prometheus stack completely. For example, deleting CRDs by looking commands in official github document and, deleting these as well [https://github.com/helm/charts/issues/19928]

kubectl delete validatingwebhookconfigurations.admissionregistration.k8s.io prometheus-prometheus-oper-admission kubectl delete MutatingWebhookConfiguration prometheus-prometheus-oper-admission
