#########################
# Polar needs c-lightning compiled with the DEVELOPER=1 flag in order to decrease the
# normal 30 second bitcoind poll interval using the argument --dev-bitcoind-poll=<seconds>. 
# When running in regtest, we want to be able to mine blocks and confirm transactions instantly.

# This dockerfile is meant to compile a c-lightning x64 image
# It is using multi stage build:
# * downloader: Download litecoin/bitcoin and qemu binaries needed for c-lightning
# * builder: Compile c-lightning dependencies, then c-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 ."
