Synopsis

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.5.16 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 4.5.16. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2020:4269

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:

This update fixes the following bugs among others:

Previously, a watch cache in the Kubernetes API was initialized from the global revision (etcd) and could remain for an undefined period if no changes were made. This behavior could cause the watch cache across server instances to go out of sync, resulting in "Too large resource version" errors. With this release, the reflector is fixed so that it can recover from "Too large resource version" errors and Operators are no longer stuck in a hotloop upon receiving "Too large resource version" errors. (BZ#1880324)
Previously, a metadata point that contained a username was stored in the Kubernetes label field on the PipelineRun. The label field cannot contain the character @, so email-based usernames in the label field were not valid and prevented the Pipeline from starting. With this release, the metadata point is move to the annotation field, which supports the @ character. (BZ#1883342)
Previously, the Image Registry Operator panicked because it dereferenced a nil pointer when trying to format the error message for failure to create an an Azure storage container. With this release, the error message is formatted correctly and the Operator no longer panics in this situation. (BZ#1886849)
