Frequently Asked Questions

What is RBAC in Kubernetes?
RBAC (Role-Based Access Control) is a method of regulating access to Kubernetes resources based on the roles of individual users or service accounts. It uses Roles, ClusterRoles, RoleBindings, and ClusterRoleBindings.
What is the difference between a Role and a ClusterRole?
A Role grants permissions within a specific namespace. A ClusterRole grants permissions cluster-wide or across all namespaces. Use Roles for namespace-scoped access and ClusterRoles for cluster-level resources like nodes.
How do I audit RBAC permissions?
Use 'kubectl auth can-i --list' to see permissions for a user, and 'kubectl auth can-i <verb> <resource> --as <user>' to test specific access. Tools like rakkess and kubectl-who-can help visualize RBAC configurations.
