Azure Kubernetes Service Arc Contributor Role

Creates, scales, upgrades, updates, and deletes AKS enabled by Azure Arc cluster resources and can retrieve the connected cluster's user credential. It has no Kubernetes API DataActions, so the retrieved user identity remains subject to the cluster's configured authorization.

Role-definition permissions are imported from Microsoft Learn. Practical scope, use cases, prerequisites, best practices, security considerations, assignment guidance, and relationships have been reviewed against the official sources below.

Assignable scopes (1)

Practical scope

Assign on an individual provisioned-cluster resource or its dedicated resource group. A parent assignment is inherited by every AKS Arc cluster below it and permits lifecycle changes across those clusters.

Prerequisites (2)

Best practices (2)

Security considerations (2)

Assignment guidance

Assign directly on the AKS Arc cluster or dedicated cluster resource group only to the platform team that needs both lifecycle management and user credential retrieval. Use Cluster User for credential-only access, Cluster Admin only for exceptional recovery, and Azure Arc Kubernetes data roles for workload authorization.

Common questions

When should I assign the Azure Kubernetes Service Arc Contributor Role Azure role?

Assign Azure Kubernetes Service Arc Contributor Role when you need to: Allow a platform operator to manage the lifecycle and configuration of approved AKS enabled by Azure Arc clusters and retrieve an ordinary user credential for authorized cluster access.. Practical scope: Assign on an individual provisioned-cluster resource or its dedicated resource group. A parent assignment is inherited by every AKS Arc cluster below it and permits lifecycle changes across those clusters.

What permissions does the Azure Kubernetes Service Arc Contributor Role Azure role grant?

The role definition grants 37 combined control-plane and data-plane actions. Representative operations include: Microsoft.HybridContainerService/Locations/operationStatuses/read; Microsoft.HybridContainerService/Locations/operationStatuses/write; Microsoft.HybridContainerService/Operations/read; Microsoft.HybridContainerService/kubernetesVersions/read; Microsoft.HybridContainerService/kubernetesVersions/write; and Microsoft.HybridContainerService/kubernetesVersions/delete. Review the permission sections above for the complete definition and exclusions.

What are the security risks of the Azure Kubernetes Service Arc Contributor Role Azure role?

Key considerations when assigning Azure Kubernetes Service Arc Contributor Role: Cluster lifecycle changes can affect all workloads, nodes, networking, identity, and availability on the AKS Arc cluster.; and The included user credential retrieval creates a cluster connection path even though the role has no Kubernetes API DataActions; combining it with broad Kubernetes authorization or the separate admin credential role creates end-to-end authority.. Follow the assignment guidance above and use the narrowest practical scope.
