ContainerDayVietnam2016: Containers with OpenStack
0 likes•565 views
This document discusses integrating containers with OpenStack. It outlines some of the good aspects, bad aspects, and an ugly thought around this integration. On the good side, projects like Magnum, Zun, Kuryr, Kolla, and Fuxi aim to provide container orchestration, management, networking, and storage capabilities within OpenStack. However, integrating containers poses challenges as well. The ecosystem has diverse standards for clouds and containers, making integration complex with two layers of management. This can impact user quotas, charging, and other considerations.

Docker virt driver for Nova
1. Introduced with Havana, live out-of-tree for Icehouse and Juno.
2. Talk directly with docker-agent using HTTP API and using docker
image that exported to Glance.
3. Nearly deprecated, there is only one maintainer for nova-docker
repo. [1]
4. Lack of networking and storage integration with OpenStack.

All OpenStack services are deployed in container
■ Easy for deploy, manage and upgrade.
■ Some work around from TCPCloud show they can
upgrade from Kilo to Liberty in 35s [1] deployed in
Kubernetes. Integrating with Kubernetes is also a BP of
Kolla.

- 16. MAGNUM Abstract COE as bay-model • Using Heat for orchestrating the deployment of Container on VM/bare-metal with Nova, Neutron, Glance and Ironic • The output is cluster of COE nodes that user can use COE API and Docker API to interact with. • Default come with LBaaS and Barbican (OpenStack security data service)
- 17. KURYR Bring Neutron advance features into containers. ■ Currently, Magnum use neutron for VM network only. And containers are spawned on top of these VM. ■ Aim to integrate well with Magnum
- 18. ZUN ■ New OpenStack project – launched after OpenStack Summit in April 2016. •Fork from Magnum container management coverage. •Aim for better replacement of legacy nova-docker. •Same architect with Nova. •Define abstraction API for manage container via COE or Docker native API. •Currently in initial phase.
- 19. FUXI ■ Newest OpenStack project •Aim for providing Cinder/Swift features with native container. (as Kuryr is plugin for docker libnetwork) •Currently in initial phase.

- 21. THE BAD Diverse and complex! 3
- 22. DIVERSE - De-facto standard for Cloud? - De-facto standard for Container? - Think about: 0.1 x 0.1 = 0.01
- 23. COMPLEX - Two layers of management: cloud and container. - What about user quota? - And how can we charge users?
- 24. DEMO
- 25. “ CONCLUSION
- 27. Magnum - Support LBaaS - External LB with k8s - Support Cinder, Rexray as storage - Support Flannel - Only support deploy in CoreOS, Atomic
