Description:

Multicluster engine for Kubernetes v2.8.1 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 import existing Kubernetes-based clusters for management.

After the clusters are managed, you can use the APIs that are provided by
the engine to distribute configuration that is based on placement policy.
