Extending K8S: Mutating Web hooks
We will be writing a Mutating Webhook to implement a pattern where we need to inject another container as side car. Say, we are running a rest-api container and we want to front that with nginx Container as sidecar in a Pod. This nginx container will be used to terminate SSL and act as reverse proxy for rest-api container. As a user, we will only be writing rest-api container manifest within Pod and let mutating webhook inject nginx to it.
