What is Kubernetes RBAC and how does it work?
Kubernetes RBAC (Role-Based Access Control) is a method for regulating access to resources in a Kubernetes cluster. It allows you to define roles and assign them to users or groups, controlling what actions they can perform.
Can you explain the difference between Roles and ClusterRoles?
Sure! Roles are used to grant permissions within a specific namespace, while ClusterRoles can be used across all namespaces. This means ClusterRoles have a broader scope.
How do I create a Role in Kubernetes?
To create a Role, you can use a YAML file to define the role and its permissions, then apply it using kubectl apply -f <filename>.yaml
.
What are some common use cases for RBAC?
Common use cases include restricting access to sensitive resources, allowing developers to manage their own namespaces, and implementing least privilege access.
