Open Source Summit 2k18 (Paris)
The Yocto Project (YP) is an open source collaboration project that helps developers create custom Linux-based systems regardless of the hardware architecture. The project provides a flexible set of tools and a space where embedded developers worldwide can share technologies, software stacks, configurations, and best practices that can be used to create tailored Linux images for embedded and IOT devices, or anywhere a customized Linux OS is needed.
This is a poky (v2.5 | sumo) container to build your own Linux image for whatever kind of architecture.
To run the docker container execute:
$ ./set.shThis bash script (to use at your own risk if you have sensitive data on your system) will:
- build locally the Docker image
- cleanup your system
⚠️ - create the bridge network
- run the container with
docker-compose
[¹] the container will leave in background also if you exit, so to access again execute: docker exec -it yocto zsh.
To save time if you want to run a pre-built image execute directly:
$ ./run.sh[²] the container will be removed when you exit.
All the data created with poky are persistent and stored in the volume poky.
Inside your host machine you can easily find under the path: /var/lib/docker/volumes/poky.
To boot the yocto images inside the poky container it's necessary to add the device /dev/net/tun from the host machine with the flag --device=/dev/net/tun.
To run the yocto image it's necessary to share the X11 socket as a volume.
Once you're inside the container, you can test your yocto environment in this way:
$ cd poky
$ source oe-init-build-env qemux86-build
$ bitbake core-image-minimal # requires a long time ...
$ runqemu qemux86If the bitbake process ends up fine you should be able to boot your first x86_64 Linux image built with yocto, using the core-image-minimal layer, and see something like this:
Happy hacking!
