build-l1-image

#!/usr/bin/env bash
# This script builds a docker image with a geth node and deploys the contracts to it.
#
# Usage
#
#   ./build-l1-image [rpc-port]
#
# The default rpc port is 8545.
#
# Part of the process of creating the Docker image is to deploy the L1 contracts required by the
# demo. The deployment is not completely deterministic; timing-related thingsl like block numbers
# may change. Therefore, this script will generate an env file in .env.geth, which can be used to
# override certain environment variables from .env in order to make the demo work with the new L1
# image.
#
# The script may print some errors during deployment but will retry on expected
# errors a few times. If it exits with a zero exit code it was successful.
#
# This script only works correctly if run from the root of the git repo.
