Setup RBAC

This page shows you how to setup role-based access control (RBAC) in your cluster to control the types of users that can view and create Kueue objects.

The page is intended for a batch administrator.

Before you begin

Make sure the following conditions are met:

• A Kubernetes cluster is running.
• The kubectl command-line tool has communication with your cluster.
• Kueue is installed.

This page assumes you are already familiar with RBAC in kubernetes.

ClusterRoles included in the installation

When you install Kueue, the following set of ClusterRoles are created for the two main personas that we assume will interact with Kueue:

• kueue-batch-admin-role includes the permissions to manage ClusterQueues, Queues, Workloads, and ResourceFlavors.
• kueue-batch-user-role includes the permissions to manage Jobs and to view Queues and Workloads.

Giving permissions to a batch administrator

A batch administrator typically requires the kueue-batch-admin-role ClusterRole for all the namespaces.

To bind the kueue-batch-admin-role role to a batch administrator, represented by the user admin@example.com, create a ClusterRoleBinding with a manifest similar to the following:

# batch-admin-role-binding.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: read-pods
subjects:
- kind: User
  name: admin@example.com
  apiGroup: rbac.authorization.k8s.io
roleRef:
  kind: ClusterRole
  name: kueue-batch-admin-role
  apiGroup: rbac.authorization.k8s.io

To create the ClusterRoleBinding, save the preceding manifest and run the following command:

kubectl apply -f batch-admin-role-binding.yaml

Giving permissions to a batch user

A batch user typically requires permissions to:

• Create and view Jobs in their namespace.
• View the queues available in their namespace.
• View the status of their Workloads in their namespace.

To give these permissions to a group of users team-a@example.com for the namespace team-a, create a RoleBinding with a manifest similar to the following:

# team-a-batch-user-role-binding.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: read-pods
  namespace: team-a
subjects:
- kind: Group
  name: team-a@example.com
  apiGroup: rbac.authorization.k8s.io
roleRef:
  kind: ClusterRole
  name: kueue-batch-user-role
  apiGroup: rbac.authorization.k8s.io

To create the RoleBinding, save the preceding manifest and run the following command:

kubectl apply -f team-a-batch-user-role-binding.yaml
