Hi @YoubingLi. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Test result:

./kubectl apply edit-last-applied -h | grep _

The edit-last-applied command allows you to directly edit any API resource you can retrieve via the command line tools. It will open the editor defined by your KUBE_EDITOR, or EDITOR environment variables, or fall back to 'vi' for Linux or 'notepad' for Windows. You can edit multiple objects, although changes are applied one at a time. The command accepts filenames as well as command line arguments, although the files you point to must be previously saved versions of resources.

./kubectl diff -h | grep _

KUBECTL_EXTERNAL_DIFF environment variable can be used to select your own diff command. By default, the "diff" command available in your path will be run with "-u" (unicode) and "-N" (treat new files as empty) options.

./kubectl config rename-context -h | grep _

CONTEXT_NAME is the context name that you wish change.
NEW_NAME is the new name you wish to set.
kubectl config rename-context CONTEXT_NAME NEW_NAME [options]

./kubectl config unset --help | grep _

PROPERTY_NAME is a dot delimited name where each token represents either an attribute name or a map key. Map keys may not contain dots.
kubectl config unset PROPERTY_NAME [options]
