# =============================================================================
# nomad/jobs/staging.hcl — Staging file server (Nomad service job)
#
# Part of the Nomad+Vault migration (S5.2, issue #989). Lightweight service job
# for the staging file server using Caddy as a static file server.
#
# Mount contract:
#   This job mounts the `docker/` directory as `/srv/site` (read-only).
#   The docker/ directory contains static content (images, HTML, etc.)
#   served to staging environment users.
#
# Network:
#   No external port exposed — edge proxy routes to it internally.
#   Service discovery via Nomad native provider for internal routing.
#
# Not the runtime yet: docker-compose.yml is still the factory's live stack
# until cutover. This file exists so CI can validate it and S5.2 can wire
# `disinto init --backend=nomad --with staging` to `nomad job run` it.
