Setup ImageTagMirrorSet to redirect mcr.microsoft.com/powershell to registry.ci.openshift.org/microsoft/powershell for fast local image pulls. This mirrors the functionality from cucushift-winc-prepare (PR openshift#75347) which pre-mirrors Windows images via core-services/image-mirroring/_config.yaml. Without this, Windows pods timeout pulling 1-2GB nanoserver images from mcr.microsoft.com. With mirroring, images pull from CI registry in <30 seconds. Changes: - Add setup_image_mirroring() function from cucushift-winc-prepare - Call before creating workloads to setup ITMS redirection - Remove useless 30m wait (nodes won't be Ready if not ready) - Workloads continue using mcr.microsoft.com URLs (ITMS redirects transparently)

Windows nanoserver images (1-2GB compressed) take 15-20 minutes to pull over slow Prow CI networking. Temporary workaround until PR openshift#75347 merges to main, which adds image mirroring to CI registry. After that merges, we can rebase and reduce timeout back to 5m. Changes: - Increase Windows workload timeout: 5m → 20m - Remove duplicate image mirroring code (wait for PR openshift#75347) - Add TODO to reduce timeout after PR openshift#75347 merges

PR openshift#75347 merged to upstream/main adding Windows image mirroring to CI registry. Now we can use it in BYOH workflows: Changes: - Add setup_image_mirroring() function (from cucushift-winc-prepare) - Call it before creating workloads to setup ImageTagMirrorSet - Redirects mcr.microsoft.com/powershell to registry.ci.openshift.org/microsoft/powershell - Reduce Windows workload timeout: 20m → 5m (images pull from local CI registry in <30s) This enables fast Windows container image pulls from mirrored CI registry instead of slow internet pulls from mcr.microsoft.com.

Enable Windows container tests in Prow CI by pre-mirroring Windows images to registry.ci.openshift.org and using ImageTagMirrorSet for transparent redirection. Changes: 1. Add Windows PowerShell images to supplemental CI images: - mcr.microsoft.com/powershell:lts-nanoserver-1809 (Server 2019) - mcr.microsoft.com/powershell:lts-nanoserver-ltsc2022 (Server 2022) 2. Create ImageTagMirrorSet in cucushift-winc-prepare: - Redirects mcr.microsoft.com/powershell → registry.ci.openshift.org/microsoft/powershell - Works in both connected (CI registry) and disconnected (ephemeral mirror) modes How it works: - CI infrastructure automatically mirrors images to registry.ci.openshift.org - ITMS transparently redirects image pulls during test execution - Tests continue using mcr.microsoft.com URLs in ConfigMap - No test code changes required Supported Windows versions: - Server 2019 (1809) - TODO: Remove after AMI upgrades - Server 2022 (ltsc2022) - Default Note: Server 2025 (ltsc2025) will be added when Microsoft publishes the image Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>

Enable Windows container tests in Prow CI by pre-mirroring Windows images to registry.ci.openshift.org and using ImageTagMirrorSet for transparent redirection. Changes: 1. Add Windows PowerShell images to supplemental CI images: - mcr.microsoft.com/powershell:lts-nanoserver-1809 (Server 2019) - mcr.microsoft.com/powershell:lts-nanoserver-ltsc2022 (Server 2022) 2. Create ImageTagMirrorSet in cucushift-winc-prepare: - Redirects mcr.microsoft.com/powershell → registry.ci.openshift.org/microsoft/powershell - Works in both connected (CI registry) and disconnected (ephemeral mirror) modes How it works: - CI infrastructure automatically mirrors images to registry.ci.openshift.org - ITMS transparently redirects image pulls during test execution - Tests continue using mcr.microsoft.com URLs in ConfigMap - No test code changes required Supported Windows versions: - Server 2019 (1809) - TODO: Remove after AMI upgrades - Server 2022 (ltsc2022) - Default Note: Server 2025 (ltsc2025) will be added when Microsoft publishes the image Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>

Summary
Enable Windows container tests in Prow CI by adding Windows PowerShell images and CSI driver images to the supplemental CI images registry and creating ImageTagMirrorSet for transparent redirection.
Problem
WINC tests use Windows container images from
mcr.microsoft.com/powershelland CSI driver images frommcr.microsoft.comandregistry.k8s.iowhich may not be accessible in all Prow CI environments. Tests need a reliable way to pull these images without depending on external registries.Solution
1. Pre-Mirror Windows Images to CI Registry
Added Windows PowerShell and CSI driver images to
core-services/image-mirroring/_config.yaml:PowerShell Containers:
Azure CSI Driver Images (for OCP-66352):
vSphere CSI Driver Images (for OCP-66352):
These images are automatically mirrored by CI infrastructure to
registry.ci.openshift.org.Note: Windows Server 2025 (
lts-nanoserver-ltsc2025) will be added when Microsoft publishes the image.2. Create ImageTagMirrorSet for Transparent Redirection
Updated

lts-nanoserver-1809lts-nanoserver-ltsc2022lts-nanoserver-ltsc2025Benefits
✅ No test code changes - ConfigMap still contains upstream MCR URLs
✅ Uses standard CI infrastructure - Leverages existing image mirroring system
✅ Works in multiple environments - Connected Prow, disconnected vSphere, Jenkins
✅ Simple and maintainable - No on-the-fly image mirroring during tests
✅ Covers storage tests - CSI driver images included for OCP-66352
✅ Reproducible CI - Pinned CSI driver versions ensure consistent test behavior
