RHBA-2020:5051 - Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 4.5.19 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 4.5.19. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHBA-2020:5052

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 bug among others:

• Previously, an upstream bug caused the API client to recover slowly after a TCP reset. This resulted in client logs continuously reporting `Timeout: Too large resource version errors` when connectivity was lost and then regained. This has been fixed by applying the upstream Kubernetes 1.18 fix into the Samples Operator. Now the OpenShift Controller Manager Operator does not experience the aforementioned loop of timeout messages. (BZ#1894667)
