# Node-RED container with Dashboard 2.0 baked in
# Build once; restart containers freely. NR's automatic package.json install
# at boot is slow and requires internet; this Dockerfile install is cached
# and reproducible.
#
# Docker volume pattern: ./nodered:/data is a bind mount (settings.js,
# flows.json, start.sh, package.json are host-owned); /data/node_modules
# is an anonymous volume so the bind mount doesn't clobber the installed
# deps. Docker copies the image's node_modules into the volume on first start.

FROM nodered/node-red:5.0.0

# Install Dashboard 2.0 (and any future deps) at image-build time.
# Versions are pinned in infra/nodered/package.json for reproducibility.
