Ошибка драматурга отказано в подключении в докере

#python #docker #docker-compose #playwright #playwright-python

Вопрос:

Я пытаюсь запустить тесты end-2 в docker в безголовом режиме и получаю playwright._impl._api_types.Error: net::ERR_CONNECTION_REFUSED at http://app/ . Это происходит только в chromium и firefox. Webkit работает, но есть также проблемы с поиском селекторов. Тесты E2E прошли, когда я запускал их с локального хоста. Запросы выполняются успешно, когда я делаю их с локального хоста. Также запросы выполняются успешно, когда я делаю завиток из контейнера e2e-тестов.

докер-compose.yml :

   app:
    image: ${APP}
    ports:
      - 8090:80
    environment:
      SERVICE_HOST: ${REAL_IP}:8080
      KEYCLOAK_URL: 'http://keycloak:8080'
      DOLLAR: $
    restart: unless-stopped
    command: sh -c "envsubst < /etc/nginx/conf.d/proxy.template > /etc/nginx/conf.d/default.conf amp;amp; exec nginx -g 'daemon off;'"
    depends_on:
      backend:
        condition: service_healthy


  e2e-tests:
    build: ../../auto_tests/end2end
    environment:
      SERVICE_HOST: 'http://app:80'
      HEADLESS_MODE: 1
      SERVICE_LOG_LEVEL: DEBUG
    depends_on:
      - app

Ответ №1:

Я решил свою проблему. На самом деле мой контейнер docker (интерфейс) называется «приложение», которое также является доменным именем приложения fronend. Мое приложение работает локально по протоколу http. Драйверы Chromium и geko принудительно устанавливают соединение http S для некоторых доменных имен, одним из которых является «приложение». Поэтому мне нужно сменить имя для моего контейнера docker, содержащего внешнее приложение.
