====================================================================
Summary:
The multicluster engine for Kubernetes 2.1.9 General Availability release images, which contains security fixes and update container images.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE links in the References section.
Description:
The multicluster engine for Kubernetes operator 2.1.9 images
The multicluster engine for Kubernetes operator provides the foundational components that are necessary for the centralized management of multiple
Kubernetes-based clusters across data centers, public clouds, and private
clouds.
You can use the engine to create new Red Hat OpenShift Container Platform
clusters or to bring existing Kubernetes-based clusters under management by
importing them. After the clusters are managed, you can use the APIs that
are provided by the engine to distribute configuration based on placement
policy.
