Helm Chart: selector & labels issue

[extravio]

Hi there,
I think there's a problem with the service selector and the labels on the pods.

Unless I hard-code a key pair in the services.yaml (spec.selector) and add the same one in statefulset.yaml (template.metadata.labels), my service doesn't work.

If I add extra labels in value.yml

nexus:
  extraLabels:
    app: nxrm
  extraSelectorLabels:
    app: nxrm

I get the following error:

│ Error: StatefulSet.apps "nexus-nxrm-ha" is invalid: spec.template.metadata.labels: Invalid value: map[string]string{"app.kubernetes.io/instance":"nexus", "app.kubernetes.io/name":"nxrm-ha"}: `selector` does not match template `labels`

which is pretty logical. as in statefulset.yaml , matchLabels and labels don't match

 selector:
    matchLabels:
      {{- include "nexus.selectorLabels" . | nindent 6 }}
      {{- if .Values.nexus.extraSelectorLabels }}
        {{- with .Values.nexus.extraSelectorLabels }}
          {{ toYaml . | nindent 6 }}
        {{- end }}
      {{- end }}
  template:
    metadata:
      [...]
      labels:
        {{- include "nexus.selectorLabels" . | nindent 8 }}

If I try to add

 [...]
  template:
    metadata:
      [...]
      labels:
        {{- include "nexus.selectorLabels" . | nindent 8 }}
        {{- if .Values.nexus.extraSelectorLabels }}
        {{- with .Values.nexus.extraSelectorLabels }}
          {{ toYaml . | nindent 6 }}
        {{- end }}
      {{- end }}

I still get the same error.

Could you please have a look?
