We are using prometheus-operator with the for several month which working great. Now we need to add persistent volume to save the data for 3 month and we use the following.
https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack
I've added the following: (we have gp2 storage class)
storageSpec:
volumeClaimTemplate:
spec:
storageClassName: gp2
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 50GiAnd I got error:
persistentvolumeclaim "prometheus-po-kube-prometheus-stack-prometheus-db-prometheus-po-kube-prometheus-stack-prometheus-0" not found,should I add something in addition to the values.yaml?
You are missing components reference, you have to specify for which component you define storage - prometheus.prometheusSpec
Try this:
prometheus:
prometheusSpec:
storageSpec:
volumeClaimTemplate:
spec:
accessModes: [ "ReadWriteOnce" ]
resources:
requests:
storage: 50Gi
storageClassName: gp2You can find more in values.yaml
