# Palladium Lightning — docker-compose
#
# Joins the existing `palladium-net` network created by the palladiumd compose stack.
# The palladium-node:local image must be built before this one (palladium-cli is copied from it).
#
# Usage:
#   # 1. Create .env with RPC credentials (see .env.example)
#   # 2. Ensure palladiumd is running on palladium-net
#   docker compose -f docker-compose.lightning.yml build
#   docker compose -f docker-compose.lightning.yml up -d
#
#   # Check status
#   docker logs palladium-lightning
#   docker exec palladium-lightning lightning-cli --network=palladium getinfo
