This chart is deprecated Error: INSTALLATION FAILED: failed to install CRD crds/crd-alertmanager.yaml: unable to recognize "": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"
helm install prometheus monitor/prometheus-operator --namespace prometheus
The chart prometheus-operator is deprecated!
Deprecation message:
DEPRECATED
This chart will be renamed, but first must be deprecated before the prometheus-community/helm-charts repo is indexed, so that it won't be listed in the hubs. See [this prometheus-community issue](https://github.com/prometheus-community/community/issues/28#issuecomment-670406329) for reasoning and next steps.
Try the latest one:
$ helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
$ helm repo update
$ helm install kube-prometheus-stack prometheus-community/kube-prometheus-stack --namespace prometheus
N.B.: The apiVersion for custom resource definitions (CRD) is apiextensions.k8s.io/v1 now.
