What is Kubernetes RBAC and how does it work in a namespace?
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 within specific namespaces.
Can you explain how to create a role and bind it to a user in a namespace?
Sure! To create a role, you define it in a YAML file specifying the permissions. Then, you create a RoleBinding to associate that role with a user in the desired namespace.
What permissions can I assign in a role?
You can assign permissions like get, list, create, update, delete, and watch for various resources such as pods, services, and deployments.
How do I check if a user has the right permissions?
You can use the kubectl auth can-i
command to check if a user has specific permissions for a resource in a namespace.
