OpenEBS Helm chart broken: installs resources into multiple namespaces (default + custom)

[svengreb]

I tried to install the OpenEBS Helm chart (version 4.1.0) into a custom openebs namespace, but it seems like some templates do not set the .metadata.namespace, neither through .Release.Namespace nor through a custom value. This results in some resources being created in the default namespace, e.g. serviceaccount/openebs-localpv-provisioner while serviceaccount/openebs-pre-upgrade-hook is created in the desired (openebs) namespace.

I'm very experienced with Helm and tested a lot of settings, but I also wonder why this is not a problem anyone is facing too (checked GitHub issues and other discussions). Simply following the official Helm installation documentation will result in this broken setup so it should be noticed somehow.

Here's the command I used to check the resulting manifests, using Helm's template command:

helm template openebs openebs/openebs --version 4.1.0 --namespace openebs --create-namespace

The openebs Helm chart version 4.1.0 uses version 4.0.0 of the dynamic-localpv-provisioner Helm chart where e.g. the deployment is missing the namespace key so it will be deployed into the default namespace.

My current workaround is to use the Kustomize Helm feature that sets the namespace for all resources that are namespaced.

# kustomization.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

namespace: openebs

helmCharts:
  - name: openebs
    namespace: openebs
    version: 4.1.0
    includeCRDs: true
    releaseName: openebs
    repo: https://openebs.github.io/openebs
    valuesInline:
      # …

So to summarize my questions: Is this a know problem or did I miss something, e.g. a value key where the target namespace for each subchart can be customized?
