Red Hat OpenShift Container Platform is Red Hat's cloud computingKubernetes application platform solution designed for on-premise or privatecloud deployments.Security Fix(es): kubernetes: Docker config secrets leaked when file is malformed and loglevel >= 4 (CVE-2020-8564) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.This advisory contains the container images for Red Hat OpenShift ContainerPlatform 4.6.13. See the following advisory for the RPM packages for thisrelease:https://access.redhat.com/errata/RHSA-2021:0172 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/releasenotes/ocp-4-6-release-notes.html This update fixes the following bug among others: Previously, when the installation program checked to ensure the minimum 25GB disk space was available per node, the validation only checked the OpenStack flavor and not whether the separate root disk had been attached from dedicated storage. This caused clusters using a small flavor in combination with sufficient root disk space to be refused during installation. This has been fixed by considering the additional root disk space when validating the required disk space. Now you can successfully install a cluster with a combination of flavor disk space and root disk space.
