Charts: stable/prometheus - fails with empty clusterrole ruleset

[TheKangaroo]

Describe the bug
If your render prometheus charts without psp, the clusterroles for alertmanager and pushgateways end up without any rules like:

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRole
metadata:
  labels:
    mylabel: label
  name: just-a-random-name
rules:

instead we need to add an empty array like:

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRole
metadata:
  labels:
    mylabel: label
  name: just-a-random-name
rules:
  []

Version of Helm and Kubernetes:
helm v2.14.3
k8s 1.13.x

Which chart:
stable/prometheus

What happened:

error: error validating "STDIN": error validating data: ValidationError(ClusterRole): missing required field "rules" in io.k8s.api.rbac.v1beta1.ClusterRole; if you choose to ignore these errors, turn validation off with --validate=false

What you expected to happen:
The ClusterRole should be applied successfully.

How to reproduce it (as minimally and precisely as possible):
deploy the chart without psp.

It's completely broken you can't run a command to install charts anymore.

I ran the following command from the documentation

helm install --name my-release stable/prometheus

and I got the following error

Error: validation failed: error validating "": error validating data: ValidationError(ClusterRole): missing required field "rules" in io.k8s.api.rbac.v1beta1.ClusterRole

I have been waiting for a fix for multiple days and following this thread but no updates.

Does anyone has a solution ?

If you need to install this chart right now, you can use some earlier version
helm install prometheus stable/prometheus --version 9.0.0

I'm too waiting for a response from Prometheus Chart team =)

I'm experiencing the same issue. @yousafsyed , mind opening a new ticket with the information you posted above?

[yousafsyed-bg]

@chickenbeef I think we should keep the information in this thread, for now, I am using the version of chart 9.0.0 as mentioned by @djklim87
