Windows Machine Config Operator prerequisites
The following information details the supported platform versions, Windows Server versions, and networking configurations for the Windows Machine Config Operator (WMCO). See the vSphere documentation for any information that is relevant to only that platform.
WMCO supported installation method
The WMCO fully supports installing Windows nodes into installer-provisioned infrastructure (IPI) clusters. This is the preferred OpenShift Container Platform installation method.
For user-provisioned infrastructure (UPI) clusters, the WMCO supports installing Windows nodes only into a UPI cluster installed with the platform: none field set in the install-config.yaml file (bare-metal or provider-agnostic) and only for the BYOH (Bring Your Own Host) use case. UPI is not supported for any other platform.
WMCO 9.y supported platforms and Windows Server versions
The following table lists the Windows Server versions that are supported by WMCO 9.y, based on the applicable platform. Windows Server versions not listed are not supported and attempting to use them will cause errors. To prevent these errors, use only an appropriate version for your platform.
| Platform | Supported Windows Server version |
|---|---|
Amazon Web Services (AWS) |
|
Microsoft Azure |
|
VMware vSphere |
Windows Server 2022, OS Build 20348.681 or later |
Google Cloud Platform (GCP) |
Windows Server 2022, OS Build 20348.681 or later |
Nutanix |
Windows Server 2022, OS Build 20348.681 or later |
Bare metal or provider agnostic |
|
-
For disconnected clusters, the Windows AMI must have the EC2LaunchV2 agent version 2.0.1643 or later installed. For more information, see the Install the latest version of EC2Launch v2 in the AWS documentation.
Supported networking
Hybrid networking with OVN-Kubernetes is the only supported networking configuration. See the additional resources below for more information on this functionality. The following tables outline the type of networking configuration and Windows Server versions to use based on your platform. You must specify the network configuration when you install the cluster.
