The document discusses Clocker, an open source application that provides Docker container management and orchestration capabilities. It summarizes Clocker's key features as managing Docker clusters across clouds, serving containers on demand, and managing composite application deployments. It also discusses Clocker's use of Apache Brooklyn for application modeling and Calico for software-defined networking between containers.
