RHBA-2021:2100 - Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 4.6.31 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 4.6.31. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHBA-2021:2101

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/4.6/release_notes/ocp-4-6-release-notes.html

This update fixes the following bugs among others:

• Previously, the node-exporter daemonset's mountstats collector caused high memory usage on nodes with NFS mount points. By disabling the mountstats collector, this fix reduces memory usage. (BZ#1955471)
