RHBA-2021:0510 - OpenShift Container Platform 4.6.18 bug fix update

Synopsis

OpenShift Container Platform 4.6.18 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.6.18 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 4.6.18. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2020:0511

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/release_notes/ocp-4-6-release-notes.html

This update fixes the following bugs among others:

  • Previously, when Conditional Tasks failed, they would be improperly read by the UI and show as pending. As a result, the Pipeline run would show a permanent pending status for each failed task. This update applies both the skipped icon and the color grey to the task when it fails to be read. Thus, users now see Conditional Tasks that have failed as skipped instead of pending, providing a clearer picture of the Pipeline run state.

  • Previously, some Helm chart repositories generated unresolvable relative URLs, which were unreachable while instantiating a helm release from a chart. This update ensures that relative chart URLs are translated to absolute (reachable) URLs while instantiating a release from a chart.

  • Previously, if the hostname from the vSphere metadata was not set before the NetworkManager started, the vSphere metadata would be ignored. This update now sets the hostname as vsphere-hostname.service before the NetworkManager starts, so long as this information is available within the vSphere metadata.

  • Previously, pull secret errors where the authorization key was not base64 encoded were not propagated through the build stack; this made determining the root cause of build errors difficult. This update allows errors like invalid key build pull to propagate through the build stack. As a result, determining the root cause of pull secret errors is now easier for users.

  • Previously, if the DeploymentConfig API returned more than 250 Pods, some Pod information was unavailable. As a result, the OpenShift desktop application would crash. This update ensures that the application does not crash when the project contains more than 250 Pods.
