There were 4 New pull requests:

  • 1528: (234/234) installer: Enabling CAPI-based Installations in openshift-install (patrickdillon) (CORS-2840)

    This enhancement discusses how openshift-install can use cluster-api (CAPI) providers to provision cluster infrastructure, without requiring access to an external management cluster or a local container runtime. By running a Kubernetes control plane and CAPI-provider controllers as subprocesses on the installer host, openshift-install can use CAPI and its providers in a similar manner to how Terraform and its providers are currently being used.

  • 1530: (5/5) release-controller: handle QE jobs in release-controller (jianzhangbjz) (edit)

    Currently, the QE jobs get run after the payload labeled with Accepted. But, the test results are not reflect on the payload after job finished. We are proposing to leverage release-controller to implement it.

  • 1531: (87/87) windows-containers: WINC-1174: WinC Disconnected Support (saifshaikh48) (OCPSTRAT-619) (WINC-936)

    do-not-merge/work-in-progress, jira/valid-reference

    The goal of this enhancement is to support Windows Containers in environments with restricted networks where hosts are intentionally impeded from reaching the internet, also known as disconnected or "air-gapped" clusters. Currently, Windows nodes configured by the Windows Machine Config Operator (WMCO) rely on `containerd``, the OpenShift-managed container runtime, to pull workload images. Also, the WMCO today is required to make an external request outside the cluster's internal network to pull the pause image. To support disconnected environments, all images need to be pulled from air-gapped mirror registries, whether that be the OpenShift internal image registry or other private registries.

    There already exists a protocol for users to publish registry mirroring configuration, namely ImageDigestMirrorSet (IDMS), ImageTagMirrorSet (ITMS) cluster resources. These are consumed by OpenShift components like the Machine Config Operator (MCO) to apply the settings to Linux control-plane and worker nodes, Windows worker nodes do not currently consume or respect mirror registry settings when pulling images. This effort will work to plug feature disparity by making the WMCO aware of mirror registry settings at operator install time and reactive during its runtime.

  • 1532: (4/4) node-tuning: CNF-10784: Mixed cpu node plugin - Enhancement update (Tal-or) (CNF-7603) (1421) (mixed-cpu-node-plugin)

    jira/valid-reference

    Resources management (particularly CPUs) in Kubernetes/OpenShift is limited and not flexible enough to cover all of our customer use cases. This enhancement introduces a runtime-level approach for extending CPU resources management on top of Kubernetes and OpenShift platforms. With the existing CPU management design, a container can either request exclusive CPUs or shared CPUs, while with this feature, it would be possible for container workload to request for both.
