-## Docker deployment
-
-The root `compose.yaml` runs Laravel with PHP 8.4 FPM, Nginx, MySQL 8,
-the database-backed queue worker, and the scheduler. It does not include or
-configure Caddy; an existing reverse proxy can forward traffic to Nginx on
-`127.0.0.1:8085`.
-
-First run:
-
-```bash
-cp .env.example .env
-```
-
-Set private values in `.env`, including:
-
-```dotenv
-APP_URL=http://localhost:8085
-APP_KEY=
-DB_HOST=db
-DB_DATABASE=nextchair
-DB_USERNAME=nextchair
-DB_PASSWORD=replace-with-a-private-password
-DB_ROOT_PASSWORD=replace-with-a-private-root-password
-```
-
-Then build and start the stack:
-
-```bash
-docker compose build
-docker compose up -d
-docker compose exec app php artisan key:generate
-docker compose exec app php artisan migrate
-```
-
-Migrations are intentionally not run by container startup. To inspect the
-application logs:
-
-```bash
-docker compose logs -f app nginx queue scheduler db
-```
-
-The default host binding is `127.0.0.1:8085:80`. Override it with
-`NEXTCHAIR_HTTP_BIND` and `NEXTCHAIR_HTTP_PORT` in `.env` when needed. MySQL
-has no published host port and is reachable only as `db:3306` inside Compose.
