This document will explain docker UCP for Enterprise grade cluster management
What is Docker UCP
Docker Universal Control Plane (UCP) is the enterprise-grade cluster management solution from Docker. You install it on-premises or in your virtual private cloud, and it helps you manage your Docker swarm and applications through a single interface.
Universal Control Plane is a containerized application that runs on Docker Enterprise Edition and extends its functionality to make it easier to deploy, configure, and monitor your applications at scale.
UCP also secures Docker with role-based access control so that only authorized users can make changes and deploy applications to your Docker cluster.
