// This code decides which ones live or die.
// The return value used is whether c was used.
// c is never closed.

`kube-apiserver` cannot resolve in-cluster DNS as that would be a layering violation). `host` may also be an IP address.\n\nPlease note that using `localhost` or `127.0.0.1` as a `host` is risky unless you take great care to run this webhook on all hosts which run an apiserver which might need to make calls to this webhook. Such installs are likely to be non-portable, i.e., not easy to turn up in a new cluster.\n\nThe scheme must be \"https\"; the URL must begin with \"https://\".\n\nA path is optional,...
