title: How to get annotation from namespace in side car injector
body: <p>I am working with Istio. There are certain annotations that we add to our kubernetes namespace. One out of these namespace annotations also needs to be applied to the pods that are created with <code>sidecar-enabled=true</code> label. For this purpose, I looked at using the Istio sidecar injector webhook, but I am not able to find the reference to namespace's annotations.</p>
  
  <p>Is there a way to do this?</p>
