Dockerfile

# Note: this is cross-building for armv7l, which is the architecture of the Kobo Elipsa 2E devices
# This Dockerfile is meant to be used only to support the build of the KoboRoot.tgz
# The final image is based on scratch, with the binary, the ca-certificates and any other content to ship to the device.
# The image is squashed and stored as KoboRoot.tgz for the release.
