OpenStack Foundation Publishes White Paper on Containers Integration, Highlights Cross-Community Accomplishments

Like R2-D2 and C-3PO, some duos seem destined to work together to make the universe a better place. Add OpenStack and Kubernetes to that list: a new white paper issued today documents the power of using these two open source software projects in tandem.

The white paper was developed by SIG-Kubernetes, an OpenStack special interest group focused on cross-community efforts with Kubernetes. Today at the OpenStack Summit, the group highlighted recent OpenStack-Kubernetes integration milestones.

White Paper: "Leveraging Containers and OpenStack: A Comprehensive Review"

The white paper published today highlights scenarios for combining OpenStack and Kubernetes and provides an overview of the open source projects, both OpenStack and otherwise, that help deliver container applications. The white paper also explores how these members of the OpenStack community are using containers in production to solve challenges and unlock new capabilities:

  • AT&T, one of the largest telecommunications companies in the world.
  • CERN, the European Organization for Nuclear Research, where physicists and engineers probe the fundamental structure of the universe.
  • SK TelecomSouth Korea's largest telecommunications operator.
  • Superfluidity, a European Research project (Horizon 2020) trying to build the basic infrastructure blocks for 5G networks by leveraging and extending well known open source projects.

Collaborators on the white paper include representatives from AT&T, Betacloud Solutions, Catalyst IT, CERN, Huawei, Linux Academy, the OpenStack Foundation, Red Hat, SK Telecom and Vexxhost.

Progress on OpenStack-Kubernetes Integration Efforts

  • The OpenStack Cloud Provider, an external cloud controller manager for running Kubernetes in an OpenStack cluster, has a permanent new home. Cloud Provider OpenStack gives Kubernetes direct access to OpenStack resources such as Nova compute instance information, Cinder block storage, and Neutron and Octavia load balancing.
  • The latest release of the CNCF dashboard features OpenStack as one of the target public clouds. This CI system runs nightly test jobs against CNCF projects. It uses a cross-cloud deployment tool to build a multi-node, highly available Kubernetes cluster. It runs Kubernetes end-to-end tests against the installation and also tests other cloud-native applications like Helm and Prometheus on the OpenStack-hosted Kubernetes test cluster.
  • Cinder now offers one integration point for over 80 different storage options through a single Cinder API with a choice of Flex or Container Storage Interface (CSI) drivers.
  • The community has documented how to Integrate Keystone authentication and authorization with Kubernetes role-based access control (RBAC). This approach allows Kubernetes to use OpenStack Keystone as an identity service.

Containers in the Spotlight at OpenStack Summit This Week

More than 70 sessions on container infrastructure are being presented at the OpenStack Summit this week. Session videos from organizations including Google, Heptio, Intel, OpenLab, Vexxhost, and Yahoo! Japan will be available at
