RHBA-2020:3188 - OpenShift Container Platform 4.5.5 bug fix update

Synopsis

OpenShift Container Platform 4.5.5 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.5.5 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 4.5.5. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2020:3189

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:

https://docs.openshift.com/container-platform/4.5/release_notes/ocp-4-5-release-notes.html

This update fixes the following bugs among others:

  • Previously, if a Dockerfile used in Docker strategy builds used the ARG instruction to define build arguments before the first FROM instruction occurred in the Dockerfile, that instruction was dropped when the Dockerfile was preprocessed to incorporate any overrides that were specified in the Build or BuildConfig. References to those arguments were subsequently not resolved properly while building an image using the preprocessed Dockerfile. The preprocessing logic has been modified to preserve ARG instructions which are encountered before the first FROM instruction when generating the updated Dockerfile contents, so this problem no longer occurs. (BZ#1843405)

  • Previously, the Operator Hub in the web console sometimes showed the incorrect icon for an Operator. The issue has been resolved in this release. (BZ#1846194)

  • Previously, the autoscaler did not balance workloads across different failure domains if a memory discrepancy of more than 128 MB existed between nodes of the same type. With this release, the maximum memory discrepancy is increased to 256 MB. (BZ#1846967)

  • Previously, when all receivers were removed from the Alertmanager page, refreshing the page caused an error. With this release, the page loads correctly with a message indicating that no receivers are found. (BZ#1851088)

  • In this release, a broken link to the cluster monitoring documentation from the web console OperatorHub install page is corrected. (BZ#1856948)

  • Previously, the Deployment Configuration Overview page sometimes crashed with the error e is undefined when a new Pod was starting up. The issue has been resolved in this release. (BZ#1857821)

  • Previously, intermittent availability issues with the API server could lead to intermittent issues with the OpenShift Controller Manager Operator retrieving deployments. Failure to retrieve a deployment sometimes caused the Operator to panic. With this release, checks have been added to handle and report this error condition, and to retry the operation. The Operator now properly handles intermittent issues retrieving deployments from the API server. (BZ#1860397)
