# deployment

Production runs the frontend/nginx, ASP.NET API, AI sidecar, and configured database through Docker
Compose. The backend is not published directly; nginx proxies `/api`. `deploy/deploy.sh` validates
configuration, takes and verifies a provider-appropriate backup before replacement, builds/restarts the
stack, and performs health checks.

Production commands explicitly select `docker-compose.yml`; it publishes no application ports.
Traefik reaches frontend/nginx over `jobtracker_shared`, must match the canonical Host exactly, and
must replace `X-Forwarded-For` and `X-Forwarded-Proto`. Nginx passes those sanitized values to the
backend over the dedicated `WEB_PROXY_SUBNET`; nginx also derives its only application server name
from `APP_PUBLIC_BASE_URL` and rejects unknown Hosts except its liveness endpoint. The backend trusts
only the dedicated CIDR and one forwarded hop. Local development explicitly adds
`docker-compose.dev.yml`, which publishes ports 3000/5202, uses the localhost origin, and disables
forwarded-header trust.

Each service rotates local Docker logs at 10 MB and retains three files. Add a central sink only if
cross-host search or longer retention becomes necessary.

Use `deploy/README.md`, `deploy/first-production-deployment.md`, and
`docs/deployment/backup-restore.md` as the operational runbooks.
