Chapter 2. Getting started with hosted control planes
To get started with hosted control planes for OpenShift Container Platform, you first configure your hosted cluster on the provider that you want to use. Then, you complete a few management tasks.
You can view the procedures by selecting from one of the following providers:
2.1. Bare metal
- Hosted control plane sizing guidance
- Installing the hosted control plane command line interface
- Distributing hosted cluster workloads
- Bare metal firewall and port requirements
- Bare metal infrastructure requirements: Review the infrastructure requirements to create a hosted cluster on bare metal.
Configuring hosted control plane clusters on bare metal:
- Configure DNS
- Create a hosted cluster and verify cluster creation
-
Scale the
NodePoolobject for the hosted cluster - Handle ingress traffic for the hosted cluster
- Enable node auto-scaling for the hosted cluster
- Configuring hosted control planes in a disconnected environment
- To destroy a hosted cluster on bare metal, follow the instructions in Destroying a hosted cluster on bare metal.
- If you want to disable the hosted control plane feature, see Disabling the hosted control plane feature.
2.2. OpenShift Virtualization
- Hosted control plane sizing guidance
- Installing the hosted control plane command line interface
- Distributing hosted cluster workloads
- Managing hosted control plane clusters on OpenShift Virtualization: Create OpenShift Container Platform clusters with worker nodes that are hosted by KubeVirt virtual machines.
- Configuring hosted control planes in a disconnected environment
- To destroy a hosted cluster is on OpenShift Virtualization, follow the instructions in Destroying a hosted cluster on OpenShift Virtualization.
- If you want to disable the hosted control plane feature, see Disabling the hosted control plane feature.
2.3. Amazon Web Services (AWS)
- AWS infrastructure requirements: Review the infrastructure requirements to create a hosted cluster on AWS.
- Configuring hosted control plane clusters on AWS: The tasks to configure hosted control plane clusters on AWS include creating the AWS S3 OIDC secret, creating a routable public zone, enabling external DNS, enabling AWS PrivateLink, and deploying a hosted cluster.
- Deploying the SR-IOV Operator for hosted control planes: After you configure and deploy your hosting service cluster, you can create a subscription to the Single Root I/O Virtualization (SR-IOV) Operator on a hosted cluster. The SR-IOV pod runs on worker machines rather than the control plane.
- To destroy a hosted cluster on AWS, follow the instructions in Destroying a hosted cluster on AWS.
- If you want to disable the hosted control plane feature, see Disabling the hosted control plane feature.
2.4. IBM Z
Hosted control planes on the IBM Z platform is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
2.5. IBM Power
Hosted control planes on the IBM Power platform is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

2.6. Non bare metal agent machines
Hosted control planes clusters using non bare metal agent machines is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
