What is Kubernetes authorization and how does it work?

Kubernetes authorization is the process of determining whether a user or service account has permission to perform a specific action on a resource. It works through various mechanisms like Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), and Webhook authorization.

Can you explain Role-Based Access Control in Kubernetes?

Sure! RBAC in Kubernetes allows you to define roles and assign them to users or groups. A role contains rules that define what actions can be performed on which resources. This way, you can control access based on the roles assigned to users.

What are the differences between RBAC and ABAC?

RBAC is based on predefined roles, while ABAC uses attributes (like user, resource, and environment) to make access decisions. ABAC is more flexible but can be more complex to manage.

How can I implement RBAC in my Kubernetes cluster?

You can implement RBAC by creating Role or ClusterRole resources that define permissions, and then binding them to users or service accounts using RoleBinding or ClusterRoleBinding.
