+# Dubizzle scraper
+
+Сервис для сбора объявлений с `dubizzle.com`.
+
+Основной сценарий работы:
+
+- discovery списка машин через `Algolia`
+- при необходимости fallback на сайт
+- нормализация полей автомобиля
+- upsert в PostgreSQL
+- периодический запуск через `Celery Beat`
+
+## Что делает проект
+
+Проект:
+
+- собирает все доступные машины из каталога `Dubizzle`
+- использует `Algolia` как основной источник discovery
+- обходит лимит одного запроса через сегментацию каталога
+- сохраняет автомобили и изображения в PostgreSQL
+- отдает API для просмотра данных и запуска задач
+- поддерживает hourly/full scan через `Celery`
+
+## Текущая архитектура
+
+Сейчас проект настроен под `Dubizzle`.
+
+Ключевые особенности:
+
+- пакет проекта: `dubizzle_scraper`
+- режим discovery по умолчанию: `algolia`
+- full scan включен по умолчанию
+- авто-сегментация: `DUBIZZLE_LISTING_SEGMENTS=auto`
+- параллельный запуск сегментов: `CELERY_PARALLEL_SEGMENTS=true`
+
+### Как собирается весь каталог
+
+Один широкий запрос в `Algolia` упирается примерно в лимит $10{,}000$ доступных результатов. Поэтому проект использует сегментацию по годам.
+
+Авто-сегменты (`auto`) сейчас разбивают каталог на 8 диапазонов по году:
+
+- `1900-2012`
+- `2013-2015`
+- `2016-2017`
+- `2018-2019`
+- `2020-2021`
+- `2022-2023`
+- `2024-2025`
+- `2026-2027`
+
+Если сегмент все равно слишком большой, discovery дополнительно режет его по `id`-диапазонам.
+
+## Стек
+
+- `Python 3.11+`
+- `Playwright`
+- `FastAPI`
+- `Celery`
+- `Redis`
+- `PostgreSQL`
+- `SQLAlchemy`
+- `Alembic`
+- `Docker Compose`
+
+## Быстрый старт через Docker
+
+Это основной рекомендуемый способ запуска.
+
+### 1. Подготовить окружение
+
+```bash
+cp .env.example .env
+```
+
+Если нужно, отредактируй `.env`.
+
+### 2. Запустить стек
+
+```bash
+docker compose up -d
+```
+
+Поднимутся сервисы:
+
+- `postgres`
+- `redis`
+- `migrate`
+- `api`
+- `worker`
+- `beat`
+
+### 3. Проверить статус
+
+```bash
+docker compose ps
+```
+
+API будет доступен по адресу:
+
+- `http://localhost:18000`
+- Swagger: `http://localhost:18000/docs`
+
+> Порт пробрасывается как `${DUBIZZLE_API_HOST_PORT:-18000}:8000`.
+
+## Полный сброс и чистый старт
+
+Если нужен запуск с нуля с чистой БД и чистым Redis:
+
+```bash
+docker compose down -v --remove-orphans
+docker compose up -d --build
+```
+
+Важно:
+
+- `docker compose down` **не удаляет volume**
+- `docker compose down -v` удаляет данные `PostgreSQL` и `Redis`
+
+## Основные Docker-сервисы
+
+### `postgres`
+
+PostgreSQL база проекта.
+
+По умолчанию:
+
+- DB: `dubizzle_scraper`
+- user: `dubizzle`
+- password: `dubizzle`
+- host port: `15432`
+
+### `redis`
+
+Используется как:
+
+- broker для `Celery`
+- backend для task state
+- хранилище progress/state ключей
+
+По умолчанию host port: `16379`
+
+### `migrate`
+
+Отдельный сервис, который выполняет:
+
+```bash
+alembic upgrade head
+```
+
+### `api`
+
+Запускает:
+
+```bash
+uvicorn dubizzle_scraper.api.app:app --host 0.0.0.0 --port 8000
+```
+
+### `worker`
+
+Запускает `Celery worker` и выполняет scraping-задачи.
+
+### `beat`
+
+Планировщик periodic tasks.
+
+По умолчанию проект настроен на запуск каждые `60` минут.
+
+
+## Ручной запуск задач в Docker
+
+### Разовый sync listing
+
+```bash
+docker compose run --rm --profile manual sync
+```
+
+По умолчанию это запустит:
+
+```bash
+dubizzle sync-listing --limit 100 --output /app/artifacts/json/docker_sync_listing.json
+```
+
+Результат будет на хосте в:
+
+- `artifacts/json/docker_sync_listing.json`
+
+### Запуск с другим лимитом
+
+```bash
+docker compose run --rm --profile manual -e DUBIZZLE_SYNC_LISTING_LIMIT=500 sync
+```
+
+### Запуск непрерывного режима
+
+```bash
+docker compose up -d api worker beat
+```
+
+## Локальный запуск без Docker
+
+Локальный запуск возможен, но проект в первую очередь ориентирован на `PostgreSQL + Redis`.
+
+### Установка
+
+```bash
+pip install -e .
+playwright install chromium
+```
+
+### Миграции
+
+```bash
+alembic upgrade head
+```
+
+### Запуск API
+
+```bash
+uvicorn dubizzle_scraper.api.app:app --reload --port 8000
+```
+
+### Запуск worker
+
+```bash
+celery -A dubizzle_scraper.worker.celery_app worker --loglevel=info --concurrency=1 --pool=solo -Q scraping
+```
+
+### Запуск beat
+
+```bash
+celery -A dubizzle_scraper.worker.celery_app beat --loglevel=info
+```
+
+
+### Полный sync листинга
+
+```bash
+dubizzle sync-listing --limit 100
+```
+
+Если включена сегментация и не переданы `make`, `model`, `limit`, CLI автоматически пойдет в segmented sync.
+
+## API
+
+Базовые роуты:
+
+### Health
+
+- `GET /health`
+
+### Машины
+
+- `GET /api/v1/cars`
+- `GET /api/v1/cars/{car_id}`
+- `GET /api/v1/cars/by-origin/{origin_id}`
+- `GET /api/v1/stats`
+
+### Задачи
+
+- `POST /api/v1/tasks/sync-vehicle`
+- `POST /api/v1/tasks/sync-listing`
+- `GET /api/v1/tasks/{task_id}`
+- `GET /api/v1/sync-runs`
+
+### Пример запуска sync vehicle
+
+```bash
+curl -X POST http://localhost:18000/api/v1/tasks/sync-vehicle \
+  -H "Content-Type: application/json" \
+  -d '{"vehicle_url": "https://www.dubizzle.com/VehicleDetail/45089484~US"}'
+```
+
+### Пример запуска sync listing
+
+```bash
+curl -X POST http://localhost:18000/api/v1/tasks/sync-listing \
+  -H "Content-Type: application/json" \
+  -d '{"limit": 100, "only_new": false}'
+```
+
+## Тесты
+
+```bash
+pytest -q
+```
+
+Тесты покрывают:
+
+- mapper
+- parser
+- listing
+- scraper
+- worker tasks
+- resilience
+- self-heal
+- db
