# Tempo node requires consensus parameters even for follower/RPC nodes.
# A signing key is generated automatically on first run if /secrets/validator_key.json does not exist.

# Usage:
#
# mkdir rpc && cd rpc
#
# git init
# git remote add origin https://github.com/StakeSquid/ethereum-rpc-docker.git
# git fetch origin vibe
# git checkout origin/vibe
#
# docker run --rm alpine sh -c "printf '0x'; head -c32 /dev/urandom | xxd -p -c 64" > .jwtsecret
#
# env
# ...
# IP=$(curl ipinfo.io/ip)
# DOMAIN=${IP}.traefik.me
# COMPOSE_FILE=base.yml:rpc.yml:tempo/reth/tempo-mainnet-reth-pruned-trace.yml

# docker compose up -d
