# Lethean Staking Node — single container, no compose needed
# Runs daemon + wallet with PoS staking in one container.
#
# Build:
#   docker build -f Dockerfile.staking-node -t lthn/staking-node .
#
# Run:
#   docker run -d --name lthn-staker \
#     -p 46941:36941 -p 46942:36942 -p 46944:36944 \
#     -v lthn-chain:/data -v lthn-wallet:/wallet \
#     lthn/staking-node
#
# Run with password:
#   docker run -d --name lthn-staker \
#     -e WALLET_PASSWORD=my-pass \
#     -p 46941:36941 -p 46942:36942 -p 46944:36944 \
#     -v lthn-chain:/data -v lthn-wallet:/wallet \
#     lthn/staking-node
#
# Check status:
#   docker exec lthn-staker /status.sh
#
# Get wallet address:
#   docker exec lthn-staker /wallet-address.sh
#
# Ports:
#   36941 — Daemon RPC (chain queries)
#   36942 — P2P (open on router for full node)
#   36944 — Wallet RPC (balance, transfers)
