# Production reference: the fleet server behind Caddy.
#
# Caddy terminates TLS on 443 with a publicly trusted certificate and renews
# it automatically (ACME). The dashboard and enrolment endpoint are reachable
# only through it, port 3000 stays on the compose network and is never
# published. Plain HTTP is the tyre-kicking path in `docker-compose.yml`, for
# a server on your own machine; HTTP in production is unsupported.
#
#   1. cp Caddyfile.example Caddyfile, put your domain in it and in
#      NF_STREAM_SAN below (DNS for the name must point at this host, with
#      80 and 443 reachable for the ACME challenge).
#   2. Set NF_STREAM_SAN in the environment BEFORE the first start.
#   3. docker compose -f docker-compose.production.yml up -d
#   4. Create the first user to require dashboard sign-in:
#        docker compose -f docker-compose.production.yml exec nf-server \
#            nf-server create-operator --username admin --role owner
