Docker Yocto Builder

This version of yocto is also available on DockerHub. You can pull the docker image from DockerHub using the command:

docker pull mkilivan/docker-yocto-builder

Usage example

Supossing you're in a directory with a poky project, just run this:

docker run --rm --volume `pwd`:/tmp mkilivan/docker-yocto-builder \
       bash -c "cd poky && \
                source oe-init-build-env && \
                bitbake core-image-sato"

Possible Issues

Depending on the host system being run, when executing yocto builds, one might run into the following error:

ERROR: No space left on device or exceeds fs.inotify.max_user_watches?

Please check the max_user_watches value on your host system using:

cat /proc/sys/fs/inotify/max_user_watches

If the value is set too low (eg: 8192), use the following command to set it properly. Please ensure that you have root/sudo priviledges to do this.

sudo sysctl fs.inotify.max_user_watches=1000000

This should solve the problem with No space left on device errors.

Flash the image to SD card

Assuming an SD card is attached as /dev/sdd, you can write the image to the card as follows:

sudo dd if=./tmp/deploy/images/raspberrypi3/chaos-image-base-raspberrypi3.rpi-sdimg of=/dev/sdd
