OpenStack, the open source project that allows enterprises to run an AWS-like cloud computing service in their own data centers, added support for containers over the course of its last few releases. Running OpenStack itself on top of containers is a different problem, though. Even though CoreOS has done some work on running OpenStack in containers thanks to its oddly named Stackanetes project, that project happened outside of the OpenStack community and the core OpenStack deployment and management tools.
Soon, however, thanks to the work of Mirantis, Google and Intel, the OpenStack Fuel deployment tool will be able to use Kubernetes as its orchestration engine, too. Ideally, this will make it easier to manage OpenStack deployments at scale.
