Introducing Clocker
1 like512 views
The document introduces Clocker, a project that uses Apache Brooklyn and Docker to manage applications in the cloud. It discusses how Clocker allows defining and deploying applications using Brooklyn blueprints, configuring Docker containers, and intelligently placing and orchestrating containers across cloud infrastructure using Brooklyn's capabilities. It provides demonstrations of deploying simple and complex applications with Clocker and outlines the project's roadmap.
