# This dockerfile is meant to compile a core-lightning arm32v7 image
# It is using multi stage build:
# * downloader: Download litecoin/bitcoin and qemu binaries needed for core-lightning
# * builder: Compile core-lightning dependencies, then core-lightning itself with static linking
# * final: Copy the binaries required at runtime
# The resulting image uploaded to dockerhub will only contain what is needed for runtime.
# From the root of the repository, run "docker build -t yourimage:yourtag ."
