Add a Visitor pattern on top of ResourcesFromArgs Allows ResourcesFromArgs to return an opaque list of items and have client commands react to them. Change request.go to return apiserver errors for arbitrary status codes to better respond to generic actions that don't make sense (kubectl delete operations foo)

Use: "delete ([-f filename] | (<resource> [(<id> | -l <label>)]",
|
|
Short: "Delete a resource by filename, stdin or resource and id",
|
|
Long: `Delete a resource by filename, stdin, resource and id or by resources and label selector.
|
|
|
|
JSON and YAML formats are accepted.
|
|
|
|
If both a filename and command line arguments are passed, the command line
|
|
arguments are used and the filename is ignored.
|
|
|
|
Note that the delete command does NOT do resource version checks, so if someone
|
|
submits an update to a resource right when you submit a delete, their update
|
|
will be lost along with the rest of the resource.
|
|
|
|
Examples:
|
|
$ kubectl delete -f pod.json
|
|
<delete a pod using the type and id pod.json>
|
|
|
|
$ cat pod.json | kubectl delete -f -
|
|
<delete a pod based on the type and id in the json passed into stdin>
|
|
|
|
$ kubectl delete pods,services -l name=myLabel
|
|
<delete pods and services with label name=myLabel>
|
|
|
|
$ kubectl delete pod 1234-56-7890-234234-456456
