⁠Poky

Open Source Summit 2k18 (Paris)

⁠Description

This is a poky⁠ (v2.5 | sumo) container to build your own Linux image for whatever kind of architecture.

⁠Usage

To run the docker container execute:

$  ./set.sh

This 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 :warning:
• 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.

⁠Storage

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.

⁠Device

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.

⁠Display

To run the yocto image it's necessary to share the X11 socket as a volume.

⁠Yocto

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 qemux86

If 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!
