"Session ID: HKG18-510 Session Name: HKG18-510 - Zun - OpenStack Container Management Service Speaker: Kevin Zhao Track: Enterprise ★ Session Summary ★ OpenStack is the number 1 private cloud Open Source project and Container technology is the heart of micro service. Zun is the Container Management service in OpenStack, supporting multi-arch including both AArch64 and X86, which provides the foundation of running container as a service in private cloud. We've introduced the Capsule (the cabins) as a container group that allows all the containers within the group to share the same resources, so that the capsule can be scheduled as a co-work unit, improving the flexibility of running container in cloud - flying cabins in the cloud. I will introduce the container capsule design, basic work process and why it is an important project for AArch64 in data center, I'll also make a comparison between Zun and other container technology. The take away for audience: they will understand some key cloud computing and container orchestration technologies and get a deep understanding about the micro service backend, cloud computing framework and prototype structure, and why they are critical for Arm in the cloud computing domain. --------------------------------------------------- ★ Resources ★ Event Page: http://connect.linaro.org/resource/hkg18/hkg18-510/ Presentation: http://connect.linaro.org.s3.amazonaws.com/hkg18/presentations/hkg18-510.pdf Video: http://connect.linaro.org.s3.amazonaws.com/hkg18/videos/hkg18-510.mp4 --------------------------------------------------- ★ Event Details ★ Linaro Connect Hong Kong 2018 (HKG18) 19-23 March 2018 Regal Airport Hotel Hong Kong --------------------------------------------------- Keyword: Enterprise 'http://www.linaro.org' 'http://connect.linaro.org' --------------------------------------------------- Follow us on Social Media https://www.facebook.com/LinaroOrg https://www.youtube.com/user/linaroorg?sub_confirmation=1 https://www.linkedin.com/company/1026961"

Zun - Capsule
• Co-located and Co-scheduled
• Share the network namespace
• Share the Volume
• Share resource limits
E.G :
1. Create a Docker Sandbox
$ docker run --d –name sandbox
pause
2. Create a container by using the
sandbox
$ docker run --d
--net container: sandbox
--ipc container: sandbox
--pid container: sandbox
