Kubernetes automatically generates several environment variables for you, like SERVICE1_SERVICE_HOST and SERVICE1_SERVICE_PORT. I would like to use the value of these variables to set my own variables in the deployment.yml, like below:

env:
- name: MY_NEW_VAR
  value: ${SERVICE1_SERVICE_HOST}

For some reason Kubernetes isn't able to resolve this. When I go inside the container it turns out it has been assigned as a literal string, giving me MY_NEW_VAR = ${SERVICE1_SERVICE_HOST}.

Is there a way to assign the value of ${SERVICE1_SERVICE_HOST} instead?
