Practical Docker for OpenStack (Juno Summit - May 15th, 2014)
This document discusses using Docker containers with OpenStack. It describes installing the Nova Docker compute driver plugin to enable launching and managing Docker containers via the OpenStack Nova API. The plugin allows spawning Docker containers from images in Glance and supports basic container operations. However, some Nova features like live migration and advanced Docker capabilities are not yet supported. Using Docker with Nova provides an alternative to Heat for container orchestration with OpenStack.
