Debian branch uses resin/armv7hf-debian image as the base image. As this images have some unnecessary packages, the size of the final image will be more.
Master branch uses swapnil18/docker-arm-busybox image as base. Although this will be much smaller than the previous one, some dependencies are not met. Till the issue is fixed use the debian branch.
