Dockerfile

#
# KymFlow NiceGUI listens on port 8081 inside the image (host port 8080 stays free for local dev).
#
# Build image locally:
#   docker build -t kymflow:latest .
#
# Run locally and open in browser (CLI publishes host 8081 -> container 8081):
#   docker run --rm -p 8081:8081 kymflow:latest
#   then visit http://localhost:8081
#
# Deploy on Raspberry Pi (e.g. Cloudflare to kymflow.mapmanager.net on host port 8081):
#   docker build -t kymflow:latest .
#   docker run -d --name kymflow --restart unless-stopped -p 8081:8081 kymflow:latest
#   then verify it is reachable in a browser through your Cloudflare tunnel/domain
#
