如何在 Ubuntu 上更快、更便捷地部署物联网设备
- 1. Snap Your IoT Device on Ubuntu 在 Ubuntu 上更快、更便捷地部署物联网设备 Rex Tsai, Technical Architect 1 Sep 2017
- 2. Canonical We are the company behind Ubuntu
- 3. Canonical 总部位于英国，2004 年开始开发操作系统 关于 Canonical FOUNDED EMPLOYEES COUNTRIES 2004 520+ 35+
- 5. Ubuntu is the #1 Choice for Innovators 3 million + developers
- 7. Ubuntu ranked as 2nd most used IoT OS by Eclipse Foundation survey
- 8. Ubuntu is powering smart IoT Smart drone controllers Advanced robotics Home gateways Industrial gateways Digital Signage
- 9. ≠ Ease of development Certified platforms Wealth of libraries Security Devops for IoT MonetizationDevelopment Deployment IOT Dev Deploy - prototype to production
- 10. Difficulties of Building a Platform Business Security and OTA maintenance Devops for IoT Ecosystem building 1 2 3
- 11. Snap - a universal Linux package format Supported distros Example snaps / frameworks
- 12. Ubuntu 16.04 LTS supports snap by default
- 13. A minimal, secure, transactional Ubuntu designed for IoT
- 14. Ubuntu Core: Ubuntu optimised for IoT operations ● For production ● Optimised for security ● Small footprint < 256 Mb RAM ● Read only OS / Kernel ● White label appstore ● Contained apps ● Signed apps ● Over the Air updates ● For development ● Optimised for flexibility ● Large footprint ● Read / Write OS & Kernel ● Manual installs ● Un-contained apps ● Unsigned apps ● Manual updates ● Same code, reliability and frequent patches updates ● Same choice of library (Qt, IoT, Robotics, Computer Vision) ● Same packaging system and development environment
- 15. What is Ubuntu Core? A minimal version with the same bits as today’s Ubuntu Ubuntu Core with transactional updates Applications confined by technologies lead by Canonical Safe, reliable, worry free updates with tests and rollback Amazing developer experience with snapcraft Easily extensible Easily create app stores for all your devices
- 16. OS IMAGE SIZE Ubuntu Core 350 MB 829 MB Ubuntu Server Minimal footprint
- 17. Applications are provided as snaps! ● The snap format is a compressed filesystem with a single metadata file describing the security profile and desired integration of the snap. ● That format is shared by everyone in the snap community, regardless of their choice of store, authentication systems, licensing or host Linux distribution. ● Decisions taken now by a Technical Oversight Board that represents a range of communities and companies. ● Easy packaging system, Package it once and be in control of the version delivery and the software stack
- 18. Automatically confines applications kernel os appapp writable areawritable area Snaps are confined and isolated app writable area app writable area
- 19. Legacy Ubuntu Core Kernel Kernel Confined applications packages as a snap with dependencies Minimal OS packaged as snap Clearly defined Kernel and device packaged as snap OS packageApplication B Shared library Device driverApplicatio n A Legend: Modular and simple architecture
- 20. Transactional updates Ubuntu Core apps and Ubuntu Core itself can be upgraded atomically and rolled back if needed. Delta change is applied when updating from different versions. Snaps can be easily uninstalled (by deleting the snap package) A bulletproof approach that is perfect for deployments where predictability and reliability are paramount. It’s called “transactional” or “image-based” systems management
- 21. Transactional updates: Apps, OS and kernel Original data Writable area Original snap Upgrade Modified data during upgrade Writable area Updated snap Original data Writable area Original data is kept on device Original snap Original data Writable area Original snap Rollback on failure
- 22. All Snap Architecture In a snappy system, all software beyond the bootloader is distributed as a snap in this same format. ● The OS snap contains the core operating system. ● The kernel snap contains the kernel and hardware-specific drivers. ● The gadget snap is device specific and is used to configure a particular model of device. Ubuntu Core Kernel 4.4 Confined applications packages as a snap with dependencies Minimal OS packaged as snap Clearly defined Kernel and device packaged as snap
- 23. snapcraft.io Developers from multiple Linux distributions and companies collaborate on the “snap” universal Linux package format, enabling a single binary package to work perfectly and securely on any Linux desktop, server, cloud or device.
- 24. Snapcraft lets developers assemble their snap from existing projects, leveraging different technologies. Developer tools: Snapcraft Project A Project B Project C ...
- 25. Snapcraft pull ● Snapcraft supports several technologies through the current plugins available. ● Snapcraft is extensible and new plugins to leverage existing technologies can be developed. ● Java, Python, ROS, Go, Maven, QML, NodeJS, make, kernel are just a few examples of the languages and technologies that can be used. ● We can reuse deb packages from ubuntu Developer tools: Snapcraft plugins
