generate dynamic secret name inside kubernetes deployment file

Question

I have 2 secrets i.e. production and staging. I want to dynamically load this secret in deployment file using the environment variable being set in same file

env:
          - name: NODE_ENV
            value: "production"


 - name: general-secret
          secret:
            secretName: general-production-secret

I want to load environment specific secrets like using

        secretName: general-{{env. NODE_ENV}}-secret

Is it possible?

I think this will replay your question https://github.com/kubernetes/kubernetes/issues/52787. Anyway, you could use software like kustomize (https://kustomize.io/) to manage yaml files. — Giorgio Cerruti, Apr 28 '20 at 14:08
As far as I know there is not way to do that without using something external like `kubectl kustomize`.Sorry. — Giorgio Cerruti, Apr 28 '20 at 14:16

As far as I know, this is not possible unless you have Helm chart for your applications, then you can make this possible

this is a solution in helm chart close to what you need Dynamically accessing values depending on variable values in a Helm chart

This is correct statement. It's not possible to refer to variables on a Kubernetes Manifest. This is nos supported and that's why we have solutions like Helm and Kustomize. They exist to fill a gap and let us create manifests programmatically. – Mark Watney Apr 29 '20 at 08:23
