# DChain node environment — copy to node1.env / node2.env / node3.env and
|
|
# customise per-host. These values are read by the node binary via ENV
|
|
# fallback (flags still override).
|
|
#
|
|
# Required:
|
|
# DCHAIN_VALIDATORS Comma-separated Ed25519 pubkeys of the initial
|
|
# validator set. All three nodes must agree on
|
|
# this list at genesis; later additions happen
|
|
# on-chain via ADD_VALIDATOR.
|
|
# DCHAIN_ANNOUNCE Public libp2p multiaddr peers use to dial this
|
|
# node from the internet. e.g.
|
|
# /ip4/203.0.113.10/tcp/4001
|
|
#
|
|
# Optional:
|
|
# DCHAIN_PEERS Bootstrap peer multiaddrs. Auto-filled by
|
|
# --join if omitted.
|
|
# DCHAIN_GOVERNANCE_CONTRACT Deployed governance contract ID (hex).
|
|
# DCHAIN_RELAY_FEE µT per message when registering as a relay.
|
|
# ACME_EMAIL Email for Let's Encrypt (TLS expiry reminders).
|
|
# DOMAIN Public hostname — Caddy issues cert for this.
|
|
#
|
|
# Security:
|
|
# Key files are bind-mounted at runtime; do NOT put private keys in this
|
|
# file. Each node needs its own identity — generate with
|
|
# docker compose run --rm node1 /usr/local/bin/client keygen --out /keys/node.json
|
|
# and copy out with `docker cp`.
