In deployment.yaml
at the path
spec.template.spec.containers

It goes something like this

...
spec:
 containers:
 - name: .Chart.Name 
 image: " .Values.image.repository : .Values.image.tag "
 imagePullPolicy: .Values.image.pullPolicy 
 env: 
 - name: JPDA_ADDRESS
 value: '*:8000'
...

So, once you run the above, if you do
kubectl exec my-pod -c my-container -- "echo $JPDA_ADDRESS", it will print *:8000

It is important to understand, that Helm simply manages templates for Kubernetes objects. Helm's deployment.yaml produces a YAML spec for Kube object of kind: Deployment. So, if you want to know every possible field you can specify in deployment.yaml, you can run kubectl explain deployment --recursive anywhere you have kubectl running.

  @sushantkumar while I personally have no experience with Azure, the whole purpose of Kubernetes / Helm is to behave the same everywhere, otherwise it has failed its mission. This method definitely works in Google's GCP and in AWS and in barebone Kube and in docker-for-desktop on developer's machines. I am sure Azure will follow suit.
