Overview

Check whether an action is allowed.

VERB is a logical Kubernetes API verb like 'get', 'list', 'watch', 'delete', etc. TYPE is a Kubernetes resource. Shortcuts and groups will be resolved. NONRESOURCEURL is a partial URL that starts with "/". NAME is the name of a particular Kubernetes resource. This command pairs nicely with impersonation. See --as global flag.

Options

-A, --all-namespaces=false
If true, check the specified action in all namespaces.

--list=false
If true, prints all allowed actions.

--no-headers=false
If true, prints allowed actions without headers

-q, --quiet=false
If true, suppress output and just return the exit code.

--subresource=""
SubResource such as pod/log or deployment/scale
