This Week in Enhancements - 2022-03-18

Updates since 2022-03-11

Enhancements for Release Priorities

Prioritized Merged Changes

<PR ID>: (activity this week / total activity) summary

There was 1 Prioritized Merged pull request:

  • 1053: (42/104) agent-installer: Add agent-based installer concept (zaneb)

    The agent-based installer is an installation method for on-premises clusters, that will use a bootable, ephemeral installer image running on the hosts that are to become part of the cluster. The user will generate the image using a command-line tool. The image itself will contain components (such as assisted-service and assisted-agent) of the Assisted and Multi-Cluster Engine (MCE) installation methods. The installer will be usable in both a fully-automated workflow, where configuration is provided upfront, and an interactive workflow where the user can interact with a GUI similar to the hosted Assisted installation service.

  • 1032: (20/68) general: OpenShift CoreOS Layering (provisional) (cgwalters)

    Change RHEL CoreOS as shipped in OpenShift to be a "base image" that can be used as in layered container builds and then booted. This will allow custom 3rd party agents delivered via RPMs installed in a container build. The MCO will roll out and monitor these custom builds the same way it does for the "pristine" CoreOS image today.

    This is the OpenShift integration of ostree native containers or CoreOS layering via the MCO.

Other New Changes

<PR ID>: (activity this week / total activity) summary

There were 5 Other New pull requests:

  • 1059: (179/179) baremetal: Converge ZTP and Metal3 flows (dtantsur)

    This enhancement proposes converging two somewhat different bare-metal provisioning flows in OpenShift:

    • Standard Metal3 flow used in bare-metal IPI and [baremetal-operator][bmo]. Uses the [Ironic agent][ipa] (also known as ironic-python-agent or simply IPA) for writing the CoreOS image.
    • ZTP (Zero-Touch Provisioning) flow using the so-called live ISO Ironic and baremetal-operator feature, the assisted service and the assisted agent.

  • 1062: (4/4) storage: Update the CSI migration enhancement (bertinatto)

    do-not-merge/hold

    We want to allow cluster administrators to seamlessly migrate volumes created using the in-tree storage plugin to their counterpart CSI drivers. It is important to achieve this goal before CSI Migration feature becomes GA in upstream. This also a requirement for supporting out-of-tree cloud providers

  • 1063: (3/3) installer: add stage-based exit codes to the openshift-installer (deads2k)

    openshift-installer callers will now get more granular exit codes. Callers of openshift-installer can expect non-zero exit codes that may change over time as the openshift-installer evolves over time. openshift-installer provides no guarantee that exit codes will not change as result of changes like greater granularity, lower granularity, re-organization, or other needs. openshift-installer does guarantee that a particular exit code will not be re-used to have a different meaning in the same y-level version. openshift-installer will make reasonable efforts to avoid re-using a particular exit code to have different meanings across y-level versions, but for sufficiently compelling reasons may do so.

  • 1064: (3/3) network: Add enhancement proposal for SDN live migration (pliurh)

    Migrating the CNI network provider network of a running cluster from OpenShift SDN to OVN Kubernetes without service interruption. During the migration, we will partition the cluster into two sets of nodes controlled by different network plugins. We will utilize the Hybrid overlay feature of OVN Kubernetes to connect the networks of the two CNI network plugins. So that pods on each side can still talk to the pods on the other side.
