RHBA-2020:3719 - OpenShift Container Platform 4.5.11 bug fix update

Synopsis

OpenShift Container Platform 4.5.11 bug fix update

Type/Severity

Bug Fix Advisory None

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 as follows:

(For x86_64 architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.5.11-x86_64

The image digest is sha256:4d048ae1274d11c49f9b7e70713a072315431598b2ddbb512aee4027c422fe3e

(For s390x architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.5.11-s390x

The image digest is sha256:e4835d509fc6e22d3011fef367ae8d27b1ff038755031d52ed28d8d36ee3350d

(For ppc64le architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.5.11-ppc64le

The image digest is sha256:5aa58cfe6b7bea5769196e1b23caf54df715743d09e6de1cd8897f976ed9b635

All OpenShift Container Platform 4.5 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel.
