balena-yocto-builder
Introduction
This application allows you to offload building a balenaOS image to your balena device. This is inspired by the docker-balena project from @alexgg:
https://github.com/alexgg/docker-balena
Preparing the application
Clone the yocto repository which will be included in the image.
git clone https://github.com/balena-os/balena-intel yocto-builder/yocto
Set the MACHINE environment variable to the device type you are building.
For example, MACHINE: genericx86-64-ext.
Modify the yocto project to suit your needs.
Push the application to balenaCloud
Log into balenaCloud.
balena login
Create a fleet for this application.
balena app create balena-yocto-builder
Push the code to balenaCloud.
balena push balena-yocto-builder
Provision a balena device preferrably using a powerful x86_64 machine. The device will immediately start building the balenaOS image as soon as the container starts. Once the build completes, the image can be downloaded through a Caddy server listening on port 80. You should be able to download the images using the public device URL.
