Red Hat OpenShift Container Platform release 4.2.33 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 4.2.33. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHBA-2020:2022

This update fixes the following bugs:

• The data in the journald for facility values was not sanitized. As a result, fluentd would emit error messages at the wrong level, causing confusion to users. Now, fluentd logs at the proper debug level. (BZ#1756072)
• The NodeCA daemon did not tolerate NoSchedule, and could not be deployed on tainted nodes. Now, NodeCA tolerates NoSchedule and the daemon can manage certificates on nodes with NoSchedule options. (BZ#1808433)
• The NodeCA daemon did not tolerate the NoExecute taint, and could not manage certificates properly on tainted nodes. Now, all taints are tolerated and are synced to all nodes with any taints. (BZ#1820243)
• The OpenStack IPI installer created Security groups using `remote_group_id` to allow traffic origins. Using `remote_group_id` in the security rules causes a lot of computation by the OVS agent to generate the flows and possibly exceeding the time allocated for flow generation. In such cases, especially in environments already under stress, masters nodes were unable to communicate with worker nodes, leading the deployment to fail. Now, IP prefixes are used for whitelisting traffic origins intsead of `remote_group_id`. (BZ#1827795)

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:
