This document discusses Dockerizing OpenStack high availability services. It begins by outlining existing challenges with OpenStack HA including complex configuration, scaling complexity, and lack of automation/visibility. It then discusses how Docker can help by allowing applications and dependencies to be packaged in lightweight containers, improving scaling, density, flexibility and reducing overhead. The document provides an example of running OpenStack services like Nova API in Docker containers for improved HA and manageability. It discusses sharing images in a private Docker registry and orchestrating container management.
