RHBA-2020:2589 - OpenShift Container Platform 4.2.36 bug fix update

Synopsis

OpenShift Container Platform 4.2.36 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.2.36 is now available with updates to packages and images that fix several bugs.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.

This advisory contains the container images for Red Hat OpenShift Container Platform 4.2.36. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2020:2588

This update fixes the following bugs among others:

  • Previously, there was no suitable endpoint in the service catalog for Octavia. This caused destroying clusters on the Red Hat OpenStack Platform using installer-provisioned infrastructure to fail. This bug fix skips the load balancer resource deletion when no Octavia endpoint is found. Now all OpenStack resources linked to the cluster are removed. (BZ#1725127)

  • Previously, OLM failed to generate an upgraded CSV with a Spec.Replaces field when the following Operator conditions were met:

    • The Operator being upgraded provided a required API whose GVK had not changed since the previous version of the Operator.
    • The Operator used the skipRange field instead of the Spec.Replaces field.

The failed CSV upgrade is outlined by the following OLM sequence:

1. Add the new Operator to the generation, and mark the APIs it provides as `present`.
2. Remove the old Operator from the generation, and mark the APIs it provides as `absent`, despite being provided by the new version of the Operator.
3. Attempt to resolve the missing APIs, overwriting the new version of the Operator with a copy that does not have its `Spec.Replaces` field set.

The sequence resulted in Operators failing to upgrade to new versions. The OLM has been updated to remove the old Operator from the current generation before adding the new Operator to the new generation. The upgrade now succeeds. (BZ#1836447)

  • Previously, the garbage collection resource event queue was not configured correctly. This caused cluster-scoped resources generated for Operators managed by OLM to never be cleaned up when the Operator was uninstalled. This bug fix reconfigures the garbage collection queues with owner labels referencing any namespace to be assessed. Now cluster-scoped resources generated for Operators managed by OLM are cleaned up when the Operator is uninstalled. (BZ#1841859)

  • The Cluster Version Operator (CVO) had a race condition where it would consider a timed-out update reconciliation cycle a successful update. This only happened for restricted network clusters where the Operator timed out attempting to fetch release image signatures. This bug caused the CVO to enter its shuffled-manifest reconciliation mode, which could break the cluster if the manifests were applied in an order that the components could not handle. The CVO now treats timed-out updates as failures, so it no longer enters reconciling mode before the update succeeds. (BZ#1846177)

Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:
