Dockerfile

# syntax=docker/dockerfile:1
#
# This docker file builds a FAST, non-hermetic image for local iteration (Kurtosis / devnets / ...).
# It is NOT suitable for releases.
# To build a hermetic, reproducible image for releases, use `make dist`.
#
# Usage:
#   docker build [--build-arg BIN=beacon-chain|validator|prysmctl] -t <name> .
#   Default BIN is beacon-chain.
