BalenaOS builder (Version 0.0.1)

This repo builds a BalenaOS builder image which is then used to build a custom BalenaOS.

Build the builder

$ export RELEASE=warrior
docker build -t balena-builder:$RELEASE --build-arg FSL_BRANCH=$RELEASE --no-cache .

Use the builder to build BalenaOS

Prepare BalenaOS on host

Fetch the balena-intel sources

$ cd /build
$ git clone --recursive https://github.com/balena-os/balena-intel.git

Use the balena-builder container to build BalenaOS

Build for the current targe machine intel-nuc

$ docker run --rm -it --privileged -v /build:/home/build balena-builder ./balena-yocto-scripts/build/barys --rm-work -d --machine intel-nuc

Alternatively build all Balena supported platforms

$ docker run --rm -it --privileged -v $(pwd)/build/balena-intel:/home/build balena-builder

This will take a while
