# ElectrumX for Bitcoin, with RocksDB
# This Dockerfile is intended for modern multi-core servers with at least 16 GB of RAM.
# We compile our own free-threaded Python, with --disable-gil (which is experimental!), which makes
# ElectrumX able to truly utilise multiple CPU cores and makes processing blocks significantly faster.
#
# Build: docker build -f Dockerfile_beefyserver --pull -t electrumx .
# Run:   docker run -d --net=host -v ~/electrumx-db:/var/lib/electrumx -e DAEMON_URL="http://youruser:yourpass@localhost:8332" -e REPORT_SERVICES=tcp://example.com:50001 electrumx
# Stop:  docker stop CONTAINER_ID
