RHBA-2020:3719 - Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 4.5.11 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 4.5.11. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHBA-2020:3720

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/4.5/release_notes/ocp-4-5-release-notes.html

This update fixes the following bugs among others:

• Previously, when the KubletHealthState alert was firing for a kubelet, it would stay active even after the kubelet became healthy again. The only way to clear the alert was to restart the kubelet. The KubletHealthState alert is no longer sent once the kubelet is healthy. (BZ#1872337)
• Previously, a hardcoded value was set when calculating the end of the DHCP allocation pool when provisioning the nodes subnet. This caused an error when deploying on an OpenShift Container Platform cluster on OpenStack with a machine CIDR smaller than 18. This bug fix removes hardcoding the number of nodes and, instead, dynamically calculates the end of the DHCP allocation pool. Now it is possible to deploy a cluster on OpenStack with a machine CIDR of any length, provided it is large enough for all required nodes. (BZ#1872629)
• Previously, admin privileges for a namespace were required for users to import an image from it. This caused self-provisioned users to not successfully import images from another project for which they only had edit access. New RoleBindings were created for image-puller rights, allowing a user with edit access for the project to import or run an image from it. (BZ#1875858)

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