Description: Kubernetes Role-Based Access Control (RBAC) is a fundamental method for regulating access to resources within a Kubernetes cluster based on the roles assigned to users. This approach allows administrators to define specific permissions associated with roles, facilitating granular and secure access management. Instead of granting permissions to each individual user, RBAC allows grouping users under roles that share the same access needs, simplifying administration and enhancing security. Roles can be defined to allow specific actions, such as creating, reading, updating, or deleting resources, and can be applied at different levels of the Kubernetes hierarchy, including namespaces, pods, services, and more. This access control model is particularly relevant in cloud environments and microservices architectures, where security and access management are critical. By implementing RBAC, organizations can adopt a ‘Zero Trust’ security approach, where no entity, whether internal or external, should have access to resources without proper authorization, thus promoting a more secure and controlled environment.
