title: What is Kubernetes egress call flow?
body: <p>I am newbie to kubernetes. Trying to understand that what happens when I try to access <code>google.com</code> from inside the kubernetes pod. <br/> Will the request directly reaches the google.com (offcourse not) or some dns lookup happens in <code>/etc/hosts.allow</code> file first before the call goes outside the pod ? What is the flow or journey of the egress call? <br/>
  <strong>PS:</strong> I already have default coredns pod running.</p>
