RHBA-2021:0634 - OpenShift Container Platform 4.6.19 bug fix update

Synopsis

OpenShift Container Platform 4.6.19 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.6.19 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 4.6.19. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2021:0633

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, the httpClient() chart repository did not consider any proxy environment variable, and thus no helm charts were displayed in the Developer Catalog. This update ensures that proxy environment variables are considered by providing a http.ProxyFromEnvironment function to the Transport struct's initialization. (BZ#1919138)

  • Previously, when a Tuned profile was updated, the supervisor process would ignore profile updates and reload a valid profile. This update keeps state information about Tuned profile application successes and failures, which results in recovering from profile application failures when receiving new, valid profiles. (BZ#1920525)

  • 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. (BZ#1904825)

  • Previously, the Cluster Version Operator was not syncing ClusterVersion during graceful shutdowns. During updates, the outgoing Cluster Version Operator was likely to exit after verifying the incoming release, but before pushing the verified: true value into the ClusterVersion history. With this update, the Cluster Version Operator now provides additional time to perform a final ClusterVersion status synchronization during shutdown. As a result, the verified values of ClusterVersion are now consistently true. (BZ#1927515)

  • The dhclient binary was removed from Red Hat Enterprise Linux CoreOS (RHCOS) when the switch to using NetworkManager in the initramfs was made. Consequently, users that had configured RHCOS to use dhclient for Dynamic Host Configuration Protocol (DHCP) operations were left with systems that were unable to properly acquire a DHCP address. This update includes the dhclient binary in RHCOS, and allows RHCOS systems to perform DHCP operations using dhclient successfully. (BZ#1915997)
