Overview
Start here to choose whether to create a platform-managed cluster or onboard an existing Kubernetes environment. For the platform-level relationship between cluster responsibility, control-plane topology, and onboarding boundaries, see Cluster Management Models.

Platform-Managed Cluster Creation
For clusters that creates and lifecycle-manages, choose the creation path by the operating system of the nodes.
The creation path follows the node operating system rather than the infrastructure responsibility model described below. For example, on Bare Metal you supply the physical servers, but the nodes run Alauda OS, so Bare Metal clusters use the Alauda OS path.
Installer-Provisioned Infrastructure
In Installer-Provisioned Infrastructure (IPI), the platform provisions machines and manages node operating systems through Alauda OS. This model is used when the platform owns the supported cluster provisioning, scaling, and upgrade lifecycle for the selected provider integration.
Currently, the platform supports Alauda OS for immutable node management. For Alauda OS cluster concepts and provider-specific workflows, see Create on Alauda OS.
User-Provisioned Infrastructure
In User-Provisioned Infrastructure, users prepare physical or virtual machines before cluster creation. The platform installs and manages Kubernetes on those nodes, while node operating system management, including provisioning, patching, and replacement, remains under the user's control.
This model is suitable when organizations already have established infrastructure or operating system management procedures. For the cluster creation workflow, see Create on Non-Alauda OS.
To create and manage User-Provisioned Infrastructure clusters through APIs, see User-Provisioned Infrastructure Provider APIs.
Hosted Control Plane
Hosted Control Plane is a control-plane topology. Each hosted cluster has its own control plane, and multiple hosted control planes run as workloads on a management cluster.
In , HCP is implemented through Kamaji (TenantControlPlane).
Third-Party Cluster Onboarding
Third-party clusters are existing Kubernetes environments provided outside . They can include standard Kubernetes environments, external Kubernetes distributions, or public cloud Kubernetes services. can provide centralized governance and operations within documented prerequisites and caveats, but onboarding does not make the owner of the external cluster's Kubernetes lifecycle, node lifecycle, or provider infrastructure lifecycle.
Third-party clusters are onboarded through import or register workflows:
Provider-specific caveats can apply to certificates, audit data, control-plane metrics, ingress, storage, node operations, connectivity, and Extension compatibility. Use the import and register workflow pages for detailed prerequisites.
For onboarding workflows, see Third-Party Cluster Onboarding, Import Third-Party Clusters, and Register Cluster.
Version Compatibility
Use the Kubernetes Support Matrix to choose platform-managed cluster creation targets, verify workload-cluster upgrade prerequisites, and validate third-party cluster onboarding versions. These are separate ranges for separate decisions.
Upgrade Prerequisite Behavior
- Before you upgrade the
globalcluster, every workload cluster must run a Kubernetes version within the Compatible Versions of the target release. - The third-party onboarding range is independent from the Compatible Versions used for this upgrade prerequisite.
