What is the difference between Role and ClusterRole in Kubernetes?
An example of an AI chatbot conversation about Kubernetes Role vs ClusterRole.
What is the difference between Role and ClusterRole in Kubernetes?
In Kubernetes, a Role defines permissions within a specific namespace, while a ClusterRole defines permissions across all namespaces.
Can you give me an example of when to use each?
Use a Role when you want to grant permissions to resources in a single namespace, like allowing a user to manage pods in 'dev'. Use a ClusterRole for permissions that need to span multiple namespaces, like granting access to nodes.
Are there any limitations to using ClusterRoles?
Yes, ClusterRoles can grant permissions across namespaces, but they cannot restrict access to a specific namespace unless combined with RoleBindings.
How do I create a Role and a ClusterRole?
You can create them using YAML files and the kubectl apply command. Would you like a sample YAML for each?
