Provide the ability to clear the current kubectl context without explicitly setting a new one #483
Description
Feature Request
When attempting to run scripts we sometimes want to create and use a "temporary" context that can be easily cleaned up afterward. (as opposed to appending the --server etc arguments to every command since they may be externally loaded)
e.g
...
$originalContext = $(kubectl config current-context)
kubectl config set-context tempcontext --user=tempuser --cluster=tempcluster
kubectl config use-context tempcontext
...
do some stuff
...
kubectl config use-context $originalContext
kubectl config delete-context tempcontext
kubectl config delete-cluster tempcluster
...etc
However the delete-context result may end up with warning: this removed your active context, use "kubectl config use-context" to select a different one if there was no original context set (lets say on a fresh machine). Although the context can start as "" in the config, there is no way to just set it to "" since kubectl config use-context with no context name results in an error due to "unexpected args"
It would be nice if we could either
- Use the
use-contextcommand and provide a null or empty context (or some--cleararg) - Or provide a
kubectl config clear-context
