RHBA-2020:2129 - Bug Fix Advisory

トピック

Red Hat OpenShift Container Platform release 4.3.21 is now available with
updates to packages and images that fix several bugs.

説明

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

https://access.redhat.com/errata/RHBA-2020:2128

This update fixes the following bug among others:

• Previously, cgroup teardown was not being handled correctly during container removal. This caused Pods that exited correctly to be labeled as killed due to out of memory (OOM) exceptions. This issue was fixed by dropping the conmon monitor that incorrectly handled cgroup teardown. Now the container cgroup teardown no longer incorrectly reports OOM exceptions for the Pod. (BZ#1830141)

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/4.3/release_notes/ocp-4-3-release-notes.html
