|
Use: "delete ([-f filename] | (<resource> [(<id> | -l <label> | --all)]",
|
|
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:
|
|
|
|
// 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.
|
|
$ cat pod.json | kubectl delete -f -
|
|
|
|
// Delete pods and services with label name=myLabel.
|
|
$ kubectl delete pods,services -l name=myLabel
|
|
|
|
// Delete a pod with ID 1234-56-7890-234234-456456.
|
|
$ kubectl delete pod 1234-56-7890-234234-456456
|
|
|
|
// Delete all pods
|
|
$ kubectl delete pods --all`,
