Light virtualisation is often viewed as a security mechanism providing isolation on a production device or as a quick deployment tool for Cloud services. But it can also be used in automotive projects as a tool to ease the development phase. This talk focuses on Docker benefits for the whole development cycle of an automotive project: it can increase build speeds and allows easier sharing of common snapshots between developers. Platform and application developments can also benefit from containers at various stages. Long term support is equally made easier.

This talk focuses on Docker usages in AGL project and will demonstrate: * how to use containers to increase snapshots build speed * how to share a reference environment amongst developers * how to create a binary distribution for platform and application development * how to get ubiquity: development on the cloud, on-premises, on a single laptop * how to run some QA tasks more easily * how to use containers for long term support

This talk will focus on how to adapt an existing distro like Tizen to the IoT world and try to answer some questions:

• how 'small' is an IoT device ?
• why starting with Tizen ?
• what are the consequences on the software architecture ?
• which adjustments for which components ?

Topics:

• How 'small' is an IoT device ?

  • memory size, CPU power
  • headless or not ?
  • wireless or not ? (which connectivity)
  • power consumption

• Why Tizen ?

  • OS for everything !
  • connected
  • secure
  • Yocto-enabled

• Tizen architecture revisited

  • Tizen APIs
  • • Wearable APIs
  • • OIC APIs (or AllJoyn APIs)

• Tizen components to adjust:

  • linux kernel
  • display system: framebuffer (no GPU)
  • no graphics server (no weston, no X11)
  • embedded crosswalk on framebuffer
  • systemd -> uselessd
  • others ...

Currently, Tizen images are built with infrastructure on tizen.org. But if someone wants to customize the distro for their own requirements (specific device, pre-installed applications...), a way to do this is to setup a private build infrastructure.

In this talk, we’ll explain a method to rebuild Tizen from sources and achieve specific customizations and automate tests. The proposed infrastructure can be used during the development phase and later on for middle to long term support.

The following topics will be detailed: - general build workflow in Tizen - requirements for setting up a private build infrastructure - setup - build packages from source - publish packages in repositories - build custom Tizen images - install and test images; manually or automatically
