# Montana node — Docker runtime image.
#
# Two-stage build:
#   1. rust:1.95-bookworm — builds montana-node release binary
#   2. debian:trixie-slim — runs the binary (newer glibc covers symbols the
#      rust image links against; bookworm-slim is too old)
#
# Build context is the REPOSITORY ROOT (parent of Code/). mt-mnemonic uses
# include_str!("../../../../Montana wordlist.txt") which is checked in at
# the repo top level, so the wordlist file must be reachable from /build.
#
# Standalone build (from repo root):
#   docker build -t montana-node:local -f Code/docker/runtime/Dockerfile .
# Compose orchestration:
#   docker compose -f Code/docker/runtime/docker-compose.yml up -d --build
