This document discusses the state of Linux containers in OpenStack. It introduces Docker and how it can be used with OpenStack components like Heat and Nova. It also describes Project Kolla, which aims to deploy OpenStack services as containers to improve manageability and upgrades. Additionally, it covers Project Magnum, which provides a Containers as a Service (CaaS) API on OpenStack by integrating components like Heat, Kubernetes, Docker, and Flannel. The document ends with a question and answer section.
