RHBA-2020:3715 - Bug Fix Advisory

标题

Red Hat OpenShift Container Platform release 4.4.23 is now available with
updates to packages and images that fix several bugs.

描述

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 4.4.23. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHBA-2020:3716

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/4.4/release_notes/ocp-4-4-release-notes.html

This update fixes the following bugs among others:

• Previously, CoreDNS 1.6.6 caused intermittent `invalid memory address or nil pointer dereference` errors, followed by timeouts in Kubernetes API access. With this release, an update to CoreDNS that fixes endpoint tombstone handling errors is backported to OpenShift Container Platform to resolve the issue. (BZ#1869310)
• Previously, the Image Registry Operator prematurely reported a healthy status if jobs were running. A running job is not a dependable indicator that the Operator is truly healthy, because the job might eventually fail. With this release, the Operator ignores running jobs when determining its health status and instead relies on the status of the last finished job for more accurate reporting. (BZ#1873534)
