Integrating Docker containers in Yocto

Our use-case is to run one or more Docker containers on an embedded platform with a read-only root filesystem and no connectivity. Also, the Yocto build system itself is also containerized, which brings up additional challenges. The first part focuses on the description of the challenges raised by this use-case, which are the reproducibility of the generated image, the build-time provisioning of a container image, and the reliability of the target system - and how these requirements can be met. Integrating Docker container images in a Yocto system often implies a host-side container engine running on the build machine. Using a Docker container to perform the build phase allows the build environment to be portable and reproducible on any Linux machine. However, in our approach of embedding Docker containers, this situation requires to propose a “Docker-in-Docker” solution within Yocto. Reliability of the embedded system is one of the most important priorities and the writable backend storage options will be discussed regarding Docker's launch at boot time. Regarding all these requirements, we focus on two possibilities for integrating Docker containers within a Yocto system. The first possibility is to embed a Docker image file into the root filesystem. At boot time, the target system will launch Docker, initialize a Docker store in a writable partition from that image, in order to run it and load the Docker image archive. The second possibility is to embed the Docker store (i.e. /var/lib/docker) into the target root filesystem at build time, in which case the image will be pulled and integrated by Bitbake. Finally, a quick demonstration will highlight both possibilities with our custom meta-layer.

Rust in oe-core: Language summary, ecosystem and meta-rust merge.

Rust is a relatively new language that promises a greater degree of safety while being a statically compiled language that is approximately as performant as C or C++. It is memory-safe by default while still allowing developers to have unsafe regions thereby being suitable for high performance systems-oriented ans operating system software development. In addition to giving an overview of the language, I will explain where and who the meta-rust layer came from and what has been done to get rust merged into oe-core. Future plans and developer workflow will be presented.

Demo: Using Rust with Yocto Project

This session will focus on demonstrating how to use Rust with Yocto Project. Two basic applications will be written along with the metadata needed by the Cargo build tool. Yocto Project recipes will be generated for each application and added to a layer. An image will then be built containing both applications and this will be tested out under qemu. In addition some brief thoughts on how Rust and the Cargo build tool interact with the license compliance features of Yocto Project will be discussed. This talk is aimed at an intermediate audience.

This talk will introduce the static analysis CodeScanner and it's integration through meta-codescanner. CodeScanner uses a recording/replay approach to capture the compilation operations done and replay them with scanning enabled (this requires clang). The layer has redone the integration to be much more bitbake'ish as the integration presented on the original CodeScanner website. It allows for a much more flexible use per-package and also supports to report to the webfrontend available. Q&A and future plans will complete the session.

Scale your Development with Extensible-SDK

Application SDKs have been always part of Yocto project tools offerings, extensible-SDK however is recently added feature which enhances the SDK in few important aspects which eliminates limitations on workflow that existed with traditional Application development SDK in workflow. These features empowers the developers by enabling them to generate full platform image and also customize it. They can also generated derived eSDKs which can be distributed further downstream. Extensible SDKs however need to be maintained and processes defined around it to use it effectively in a large scale development environment with hundreds of developers working on many different machines using different machine profiles. You will learn about eSDK and how to use it as the same time how to properly care and feed it.

Pros and cons of various layer management tools

This presentation will show the pros and cons of the following ways to manage layers: using git submodules, repo, the kas tool and the combo-layer utility. The possibilities of some of them end with the preparation of appropriate layers, while others allow for selecting specific revisions, preparing the local.conf configuration file or using only a part of a given layer. Each of the above-mentioned methods will be tested on the same project to show the differences. When starting to work with layers, it is good to choose one of the ways to manage them and master it. The main goal of the presentation will be to combine these methods in one place so that everyone who starts their adventure with The Yocto Project has the opportunity to choose the tools that best suit their needs.

Prebuilt software development in OE way

Develop a OE 'bbclass' for prebuilt management (prebuilt.bblcass), which allows generation and restoration of a tarball out of ${D} directory. To use prebuilt mechanism, a recipe simply needs to inherit the 'prebuilt' class: inherit prebuilt On full source build, this recipe will automatically generate a prebuilt under deploy/: e.g. deploy/prebuilts/aarch64/vim_8.0.0983_prebuilt_aarch64.tar.gz To use above generated prebuilt tarball instead of fetching the (unavailable private) sources, set the PREBUILT_SRC_DIR variable, pointing to the provided prebuilts (e.g. in conf/local.conf). PREBUILT_SRC_DIR = "/home/oe-prebuilts/" Then for each recipe inheriting 'prebuilt' class, the prebuilt package will be installed (if available), disabling usual fetch, compile, install... tasks.

Software Updates with RAUC, the Yocto Project and OpenEmbedded

RAUC is a powerful and flexible open source solution. However, it requires advanced skills for initial integration with the Yocto Project and OpenEmbedded. The following steps are required: * Set U-Boot as a bootloader * Enabled SquashFS in the Linux kernel configurations * Set ext4 root file system * Create specific partitioning of the microSD card that matches the RAUC slots * Set U-Boot environment configurations and a script to properly switch RAUC slots * Generate certificate and set a keyring to RAUC’s system.conf The flexibility of RAUC allows covering various use cases and scenarios, including advanced options such as a single or redundant data partitions. Upgrades are performed through RAUC bundles which ca be installed the air or using the old-fashioned method with a USB stick. For managing updates to a fleet of Internet of Things, it is possible to integrate RAUC with Eclipse hawkBit project that acts as a deployment server with a nice web user interface. In this presentation we will go through all the exact steps to build a minimal image and perform end to end updates using meta-rauc and meta-raspberrypi. Both software updates over the air and through a USB stick will be demonstrated. Finally, we will discuss challenges for RAUC integration in real-world products,as well as ideas of optimizations of the build process and implementation of continuous integration (CI). The presentation is appropriate for anyone with basic knowledge about the Yocto Project and OpenEmbedded. The provided information will help other software developers in the community to overcame faster and easier similar technical difficulties while integrating the RAUC client on embedded Linux devices.

Yocto Project Kernel Lab, Hands-On

Providing a kernel is a fundamental part of creating a BSP layer for your board. But kernels can be packaged/built in several ways, and require close coupling between your bootloader, your SoC’s requirements, and your device tree. Additionally, a good BSP layer will allow users to easily configure the kernel (using auditable kernel configuration fragments), and allow users to create separate configurations for separate situations. A specific kernel configuration can dictate various parameters of the resulting image itself. This talk and hands-on lab has been designed to show the user the various options and toolings that are available, and provide concrete examples of their use.
