RHBA-2019:1866 - Bug Fix Advisory

Synopsis

OpenShift Container Platform 4.1.8 bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Red Hat OpenShift Container Platform release 4.1.8 is now available with
updates to packages and images that fix several bugs and add enhancements.

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 4.1.8. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2019:1865

This update fixes the following bugs:

  • The Marketplace Operator did not properly define related resources. The must-gather tool requires a `RelatedObjects` field in the `ClusterOperator` CR to be populated with `ObjectReferences` of the resources associated with the operator. As a result, the must-gather tool was not able to gather enough information about the Marketplace Operator. Now, the `RelatedObjects` field is populated with the Operator's namespace and the `OperatorSource/CatalogSourceConfig/Catalogsource` resources. The must-gather tool is now able to gather adequate information about the Marketplace Operator. (BZ#1717509)
  • The `openshift.io/image-signature-import` controller was previously limited to importing three signatures. This limit has been increased and signatures are imported correctly. (BZ#1722569)
  • In AWS environments, the order of the list of internal IP addresses was not preserved when a secondary IP address was added. As a result, the node would not be able to communicate to the API server. Now, the merge algorithm for IP addresses has been corrected to not re-order the IP addresses and adding a secondary IP address does not interfere with node communication. (BZ#1729276)
  • Prometheus metrics for ElasticSearch were unavailable after an update to the Prometheus plugin was performed. As a result, users were denied access to metrics. SAR configuration has now been added to the authentication change, and now the multi-tenant plugin executes SAR and allows access to the ElasticSearch metrics. (BZ#1731006)

This update includes the following enhancements:

  • A resource request was added to the node-ca pod. The pod now requires minimal guarantees about the amount of CPU and memory it will receive. (BZ#1721685)
