[NickGraham101]

Describe the bug
Deployment of kube-prometheus-stack fails with error manifest_sorter.go:192: info: skipping unknown hook: "crd-install". The CustomResourceDefinitions are still created

Version of Helm and Kubernetes:

Helm Version: 3.3.1
Kubernetes Version: 1.18.8

Which chart: prometheus-community/kube-prometheus-stack
Which version of the chart: 9.4.4

What happened: Deployment of chart returns an error:

helm.exe upgrade --install --wait --namespace prometheus-stack --version v9.4.4 kube-prometheus-stack prometheus-community/kube-prometheus-stack

Release "kube-prometheus-stack" does not exist. Installing it now.
NAME: kube-prometheus-stack
LAST DEPLOYED: Mon Sep 28 16:45:30 2020
NAMESPACE: prometheus-stack
STATUS: deployed
REVISION: 1
NOTES:
kube-prometheus-stack has been installed. Check its status by running:
  kubectl --namespace prometheus-stack get pods -l "release=kube-prometheus-stack"

Though it still seems to install all resources and Prometheus is functional, CRDs are installed:

kubectl get CustomResourceDefinition

What you expected to happen: The chart to deploy without returning an error

How to reproduce it (as minimally and precisely as possible):

helm.exe upgrade --install --wait --namespace prometheus-stack --version v9.4.4 kube-prometheus-stack prometheus-community/kube-prometheus-stack

Can confirm on:

Helm Version: 3.3.0
Kubernetes Version: 1.18.6

With below command.

helm install prometheus stable/prometheus-operator --namespace prometheus

I've retried this with version 9.4.9 of the chart but still getting the same issues

You can safely ignore this warning. See https://v3.helm.sh/docs/topics/charts_hooks/#the-available-hooks

Note that the crd-install hook has been removed in favor of the crds/ directory in Helm 3.

This hook is still part of the chart because Helm 2 support is not yet finished. After 13 Nov 2020, we can safely remove this hook from the chart. Until then, this is by design.

For more context, see helm/charts#19008

We still see this warning, is that normal?

In my case, it's not a warning, it's an error

> helm install prom prometheus-community/kube-prometheus-stack -n monitoring
