This talk will show how to create a Docker cloud using Apache Brooklyn, an ASF incubator project that provides autonomic policy based application deployment and management, in combination with Apache jclouds, the multi-cloud toolkit for the JVM to create portable applications across clouds. Clocker is an Apache licensed open source Brooklyn application that combines intelligent placement, on-demand provisioning and autonomic management of Docker containers. Clocker uses Apache jclouds to provision hosts on any supported cloud provider, and creates containers using a jclouds driver which consumes the Docker API. Clocker also extends Docker with SDN integration, using pluggable providers such as Weave. We will show how to use Apache Brooklyn to deploy and manage composite applications across multiple Docker hosts in the cloud.
