Synopsis

OpenShift Container Platform 4.5.6 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.5.6 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 4.5.6. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2020:3331

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, if the replicas field on a MachineSet was set to a nil value, the autoscaler could not determine the current number of replicas within the MachineSet and therefore could not perform scaling operations. With this release, the autoscaler uses the last number of observed replicas in the MachineSet as reported by the replicas field in the status if a nil value is set. (BZ#1820654)
Previously, a dropdown list on the Create EtcdBackup screen displayed a loading icon until the user selected an item. The dropdown list now only shows a loading icon if it is in a loading state. (BZ#1848530)
Previously, multiple correctly formatted, space-delimited values could be pasted into the Labels field of the Create Namespace modal. However, individual complex values that contain spaces were interpreted as multiple incorrectly formatted values, and could not be pasted into the field. With this release, it is no longer possible to paste multiple values in to the labels field, and the web console validates the pasted input and displays invalid pasted input in red text. (BZ#1850292)
Previously, some available networks were not shown during cluster installation because of an ovirt-engine-sdk-go API error that affected oVirt network parsing. The issue is resolved in this release. (BZ#1852722)
Previously, a Kubelet failed to start if a soft eviction threshold and grace period were not specified. With this release, the presence of these values is verified during Kubelet configuration. (BZ#1852787)
With this release, Kuryr-Kubernetes now attempts to detect the bridge interface for Pod subports on the Container Network Interface (CNI) level, instead of using a value set in kuryr.conf. This approach supports cases when VMs call the interface without using a value set in kuryr.conf. (BZ#1855773)
Previously, when a machine tried to get the resourcePoolPath, it found multiple resource pools and was unable to resolve the correct one. With this release, a property added to the machine sets with the resourcePoolPath information helps resolve the correct one. (BZ#1866539)

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