title: Kubernetes add system variable to Dockers entrypoint
body: <p>here's the problem. I've a Pod running in my cluster with angular. I want to use a System Variable in Dockers entrypoint. It would be very helpful for my use case.</p>
  
  <p>According to my understanding the entrypoint is executed as soon as you pull the image in Kubernetes.  </p>
  
  <p>So my idea is to use a system variable in Dockers Entrypoint which will be initialized later during deployment. Kubernetes set the system variable and AFTER this, the entrypoint should be execute. </p>
  
  <p>Do you have experience or do you see a mistake here?</p>
  
  <p>Thanks for your help</p>
