为什么赛普拉斯无法检测到运行网络服务器？

Question

我的容器都是运行ning，我正在尝试运行 Cypress 测试反对它：

docker-compose.yml:

version: '3.7'

services:
  
  users:
    build:
      context: ./services/users
      dockerfile: Dockerfile
    volumes:
      - './services/users:/usr/src/app'
    expose:
      - 5000
    environment:
      - FLASK_APP=project/__init__.py
      - FLASK_ENV=development
      - APP_SETTINGS=project.config.DevelopmentConfig
      - DATABASE_URL=postgresql://postgres:postgres@users-db:5432/users_dev
      - DATABASE_TEST_URL=postgresql://postgres:postgres@users-db:5432/users_test
      - SECRET_KEY='hakuna matata'
    depends_on:
      - users-db

  client:
    build:
      context: ./services/client
      dockerfile: Dockerfile
    volumes:
      - './services/client:/usr/src/app'
      - '/usr/src/app/node_modules'
    ports:
      - 3007:3000
    environment:
      - CHOKIDAR_USEPOLLING=true
      - NODE_ENV=development
      - REACT_APP_USERS_SERVICE_URL=${REACT_APP_USERS_SERVICE_URL}
    depends_on:
      - users

  users-db:
    build:
      context: ./services/users/project/db
      dockerfile: Dockerfile
    expose:
      - 5432
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres

  nginx:
    build:
      context: ./services/nginx
      dockerfile: Dockerfile
    restart: always
    ports:
      - 80:80
    depends_on:
      - users
      - client

cypress.json:

{
    "baseUrl": "http://nginx:80",
    "video": false
}

docker ps:

CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                                       NAMES

错误输出：

Cypress could not verify that the server set as your `baseUrl` is running:           

> http://nginx:80                                                                  
                                                                                                                                                 
Your tests likely make requests to this `baseUrl` and these tests will fail if you do
n't boot your server.                                                                
                                                                                                                                                 
Please start this server and then run Cypress again.

给它 http://localhost 也没有用。我正在运行ning 测试运行ner 来自容器：docker run -it -v $PWD:/e2e -w /e2e cypress/included:3.2.0

环境：

docker 版本 20.10.11，构建 dea9396

赛普拉斯 3.2.0

OS: Ubuntu Linux 20.04

如有任何建议，我们将不胜感激。

在这种情况下运行ning Cypress 时，您必须使用 host network，因为如果您不使用相同的 docker network，则无法从 cypress 访问 http://nginx:80 .您要么必须运行使用由 Docker 创建的相同网络，要么通过以下方式将 Cypress 容器网络组合或绑定到主机网络：

docker run -it -v $PWD:/e2e -w /e2e --network=host --ipc=host cypress/included:3.2.0

现在目标 localhost:80 而不是 nginx:80。
