- 2016-04-20 According to the discussion in the OpenStack Austin design summit, we are going to create a new project (which is Higgins) for providing OpenStack container service. The Magnum project (another OpenStack project for containers) will focus on deployment and management of Container Orchestration Engines (COEs).
- 2016-06-07 We renamed the project from "Higgins" to "Zun"

Frequently Asked Questions
1) What is the relationship between Zun and Magnum?
Zun and Magnum are two independent projects. Zun aims to provide APIs to manage containers, while Magnum provides APIs to provision and manage Container Orchestration Engine (COEs), such as Kubernetes.
2) Who is Zun for? In comparison, who is Magnum for?
Zun is for users who want to create and manage containers as OpenStack-managed resource. Containers managed by Zun are supposed to be integrated well with other OpenStack resources, such as Neutron network and Cinder volume. Users are provided a simplified APIs to manage containers without the need to explore the complexities of different container technologies. Magnum is for users who want a self-service solution to provision and manage a Kubernetes (or other COEs) cluster.
3) What is the difference between Zun and nova-docker?
Nova-docker allows accessing containers via Nova's API, while Zun is not bounded by Nova's API.
4) Does Zun compete with Kubernetes (or other COEs)?
We do not intend to compete with Kubernetes or other COEs. In fact, Kubernetes provides Container Orchestration and many other advanced features (i.e. keep container alive, load balancing, etc.). In comparison, Zun will start with basic container operations (i.e. CRUD) and focus on tight integration with OpenStack.
