kubectl auth can-i
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]
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 '*' '*'

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/
