Red Hat OpenShift support for Windows Containers release notes

Previously, on Azure clusters the WMCO would check if an external Cloud Controller Manager (CCM) was being used on the cluster. CCM use is the default. If a CCM is being used, the Operator would adjust configuration logic accordingly. Because the status condition that the WMCO used to check for the CCM was removed, the WMCO proceeded as if a CCM was not in use. This fix removes the check. As a result, the WMCO always configures the required logic on Azure clusters. (OCPBUGS-31704)

Previously, the kubelet was unable to authenticate with private Elastic Container Registries (ECR) registries. Because of this error, the kubelet was not able to pull images from these registries. With this fix, the kubelet is able to pull images from these registries as expected. (OCPBUGS-26602)

Previously, the WMCO was logging error messages when any commands being run through an SSH connection to a Windows instance failed. This was incorrect behavior because some commands are expected to fail. For example, when WMCO reboots a node the Operator runs PowerShell commands on the instance until they fail, meaning the SSH connection rebooted as expected. With this fix, only actualy errors are now logged. (OCPBUGS-20255)
