    // List all pods in ps output format.
    $ kubectl get pods

    // List a single replication controller with specified ID in ps output format.

submits an update to a resource right when you submit a delete, their update
will be lost along with the rest of the resource.

    // Delete a pod using the type and ID specified in pod.json.
    $ kubectl delete -f pod.json

    // Delete a pod based on the type and ID in the JSON passed into stdin.

#### resize
Set a new size for a Replication Controller.

Resize also allows users to specify one or more preconditions for the resize action.

resize is sent to the server.

    // Resize replication controller named 'foo' to 3.
    $ kubectl resize --replicas=3 replicationcontrollers foo

    // If the replication controller named foo's current size is 2, resize foo to 3.
    $ kubectl resize --current-replicas=2 --replicas=3 replicationcontrollers foo

#### expose
Take a replicated application and expose it as Kubernetes Service.
		
Looks up a ReplicationController by name, and uses the selector for that replication controller
as the selector for a new Service on the specified port.

Examples:

    // Creates a service for a replicated nginx, which serves on port 80 and connects to the containers on port 8000.
    $ kubectl expose nginx --port=80 --container-port=8000

    // Create a service for a replicated streaming application on port 4100 balancing UDP traffic and named 'video-stream'.
    $ kubectl expose streamer --port=4100 --protocol=udp --service-name=video-stream

Usage:
```

      --protocol="TCP": The network protocol for the service to be created. Default is 'tcp'.
      --public-ip="": Name of a public IP address to set for the service. The service will be assigned this IP in addition to its generated service IP.

#### label
Update the labels on a resource.

If --overwrite is true, then existing labels can be overwritten, otherwise attempting to overwrite a label will result in an error.
If --resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used.

Examples:
  // Update pod 'foo' with the label 'unhealthy' and the value 'true'.
  $ kubectl label pods foo unhealthy=true

  // Update pod 'foo' with the label 'status' and the value 'unhealthy', overwriting any existing value.
  $ kubectl label --overwrite pods foo status=unhealthy
  
  // Update pod 'foo' only if the resource is unchanged from version 1.
  $ kubectl label pods foo status=unhealthy --resource-version=1
  
  // Update pod 'foo' by removing a label named 'bar' if it exists.
  // Does not require the --overwrite flag.
  $ kubectl label pods foo bar-
