RHBA-2020:3128 - Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 4.4.15 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 4.4.15. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHBA-2020:3127

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, adding arbitrary taints to nodes could cause problems related to the DNS operator’s operand. Now the DNS operator’s operand tolerates any taint added to a node. The operand runs on and updates `/etc/hosts` on all Linux node hosts. *Missing CNI default network* events may be observed when the operand starts on a node that is still initializing, but such errors are transient and can be ignored. (BZ#1847197)
• Previously, the container image signature policy used in OpenShift Container Platform builds did not contain any configuration for local images. When only allowing images from specific registries, postCommit scripts in builds failed because it was not allowed to use local images. The container image signature policy has been updated to always allow images that reference local storage layers directly. Now builds can successfully complete if they contain a postCommit hook. (BZ#1849174)

You may download the oc tool and use it to inspect release image metadata
as follows:
