CoreOS already has its own Linux distribution stack that provides clustering and management capabilities for containers. The open-source Google Kubernetes project is an effort to enable container management as well. Multiple vendors have embraced Kubernetes, including Red Hat, which is using it as part of the upcoming OpenShift 3 platform-as-a-service (PaaS) release. OpenStack vendor Mirantis is also working with Kubernetes in an effort to bring it into the OpenStack cloud ecosystem.
