Use environment variable RequestAuthentication/AuthorizationPolicy

Is there any way to use environment variables in this file descriptors like this?

apiVersion: security.istio.io/v1beta1
kind: RequestAuthentication
metadata:
  name: my-api
spec:
  selector:
    matchLabels:
      app: my-api
  jwtRules:
  - issuer: ${ISSUER}
    jwksUri: ${JWK_URI}
    forwardOriginalToken: true

You can already do that today. Did you run into any problem?

Do you have any example for setting the values to environment variable.

Is it through the bash?
export ISSUER=XYZ

@liminwang are you able to link to any docs or provide an example of where environment variables may be set so that they may be used within a RequestAuthentication or AuthorziationPolicy?

@brunooliveiramac maybe you eventually figured this out? If so, are you able to provide some insight?

Thanks!
