Dockerfile

# Minimal Docker image demonstrating that server extensions work
# through freshell's HTTP proxy without exposing extension ports.
#
# Build:  docker build -t freshell-docker-test -f examples/docker/Dockerfile .
# Run:    docker run --rm -p 3001:3001 freshell-docker-test
# Open:   The startup URL (with token) is printed to stdout
#
# Only port 3001 is exposed. Server extensions (status-dashboard,
# live-counter) allocate dynamic ports *inside* the container, but
# their iframes load through /api/proxy/http/:port/ on port 3001,
# so the browser never needs direct access to those ports.
