2. Description:

Multicluster Engine for Kubernetes 2.3.1 images

Multicluster engine for Kubernetes 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.
