# This dockerfile is meant to cross compile with a x64 machine for a arm64v8 host
# It is using multi stage build: 
# * downloader: Download litecoin/bitcoin and qemu binaries needed for Core Lightning
# * builder: Cross 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 -f contrib/linuxarm64v8.Dockerfile ."
