The document introduces Clocker, a project that uses Apache Brooklyn and Docker to manage applications in the cloud. It discusses how Clocker allows defining application topologies and policies using Brooklyn blueprints, deploying applications into Docker containers on automated infrastructure provisioned using Brooklyn and Jclouds, and intelligently placing and orchestrating containers for auto-scaling and high availability. Examples of deploying simple and complex multi-tier applications using Clocker are also provided.
