Possible resources include pods (po), replication controllers (rc), services

(se) or minions (mi).

If you specify a Go template, you can use any field defined in pkg/api/types.go.

|
|
$ kubectl get pods

<list all pods in ps output format>
|

|
$ kubectl get replicationController 1234-56-7890-234234-456456

<list single replication controller in ps output format>
