Я вижу, что прокси не используется.
аюсь запустить Scrapy Spider с двумя «расширениями»:
всплеск для рендеринга JavaScript,Тор-Privoxy обеспечить анонимность.В качестве примера я использую скребокquotes.toscrape.com вhttps://github.com/scrapy-plugins/scrapy-splash/tree/master/example, Вот моя структура каталогов:
.
├── docker-compose.yml
└── example
├── Dockerfile
├── scrapy.cfg
└── scrashtest
├── __init__.py
├── settings.py
└── spiders
├── __init__.py
└── quotes.py
гдеexample каталог клонируется изscrapy-splash репозиторий. Я добавил следующееdocker-compose.yml файл:
version: '3'
services:
scraper:
build: ./example
environment:
- http_proxy=http://tor-privoxy:8118
links:
- tor-privoxy
- splash
tor-privoxy:
image: rdsubhas/tor-privoxy-alpine
splash:
image: scrapinghub/splash
где вsettings.py файл, который я изменилSPLASH_URL:
# SPLASH_URL = 'http://127.0.0.1:8050/'
SPLASH_URL = 'http://splash:8050'
Потому что Splash работает не на локальном хосте, а в отдельном связанном контейнере с именемsplash,Dockerfile дляscraper является
FROM python:alpine
RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl bash
RUN pip install scrapy scrapy-splash
COPY . /scraper
WORKDIR /scraper
CMD ["scrapy", "crawl", "quotes"]
Проблема в том, что когда я запускаю это с помощьюdocker-compose build а такжеdocker-compose upЯ получаю следующие журналы:

где я прервал процесс для краткости. Кажется, чтоscraper а такжеtor-privoxy службы поочередно жалуются на500 Internal Service Error и не в состоянии «решить или подключиться к адресу», соответственно.
Я изо всех сил пытаюсь выяснить, почемуhttp_proxy и Splash не «работают вместе». Может кто-то указать мне верное направление?
