Description

Hello, I've been working with the Flink Kubernetes operator and noticed that the operatorPod.env only allows for simple key-value pairs and doesn't support Kubernetes valueFrom syntax.

How about changing template to support more various k8s syntax? 

Current template

{{- range $k, $v := .Values.operatorPod.env }}
  - name: {{ $v.name | quote }}
    value: {{ $v.value | quote }}
{{- end }}

 

Proposed template
1) Modify template like below 

{{- with .Values.operatorPod.env }} 
{{- toYaml . | nindent 12 }} 
{{- end }} 

2) create extra config, Values.operatorPod.envFrom and utilize this

 

I'd be happy to implement this update if it's approved.
Thanks in advance.
