anchor.diff:  The Kubelet is responsible for handling port forward requests from clients.
   Upon receiving a request, it upgrades the response and waits for the client to
   create port forwarding streams. When it receives a new stream, it copies data
  -between the stream and the container's port.
  +between the stream and the pod's port.

  -There are a few different options for forwarding to a container's port. The
  -current implementation invokes `nsenter` directly on the host (node) to enter
  -the container's network namespace and invoke `socat` to copy data between the
  -stream and the container's port. Other options include running a "helper"
  -container that then runs `nsenter` and `socat` so those binaries aren't
  -required to be installed on the host.

  == Overview
  
  OpenShift takes advantage of a feature built into Kubernetes to support
  executing commands in containers. This is implemented using HTTP along with a
  multiplexed streaming protocol such as link:http://www.chromium.org/spdy[SPDY]
  or link:https://http2.github.io/[HTTP/2].
  
  === Client Operation
  
  
negative.code: 
  Ports may be specified using the following formats:
  
  * `5000` - the client listens on port 5000 locally and forwards to 5000 in the pod
  * `6000:5000` - the client listens on port 6000 locally and forwards to 5000 in the pod
  * `:5000` or `0:5000` - the client selects a free local port and forwards to 5000 in the pod
  
  ==== Protocol
  
  Clients initiate port forwarding to a pod by issuing a request to the
  Kubernetes API Server:
