Chapter 1. Introduction to Control Center
This chapter introduces Control Center, an open-source application service orchestrator based on Docker Community Edition (Docker CE, or just Docker).
Control Center is a platform-as-a-service framework that can manage any Docker application, from a simple web application to a multi-tiered stateful application stack. Control Center is based on a service-oriented architecture, which enables applications to run as a set of distributed services spanning hosts, datacenters, and geographic regions.
Control Center relies on declarations of application requirements to support Docker containers. A service definition template contains the specifications of application services in JSON format. The definition of each service includes the IDs of the Docker images needed to run the service.
