码头depends_on命令不起作用

Question

我正在尝试一个selenium、chrome节点和firefox节点，我的代码按照这个顺序运行测试执行脚本。我的节点取决于集线器，代码取决于两个集线器。但是，运行docker-compose --build首先构建代码，然后尝试在不启动selenium组件的情况下运行。我不知道我做错了什么。

docker-compose.yml

version: '3'
services:
  hub:
    image: selenium/hub
    networks:
      robottestsnw: {}
    ports:
    - 4444:4444

  chrome:
    image: selenium/node-chrome
    networks:
      robottestsnw: {}
    depends_on:
      - hub
    shm_size: '2g'
    environment:
      SCREEN_WIDTH: 1920
      SCREEN_HEIGHT: 1080
      HUB_HOST: hub


  firefox:
    image: selenium/node-firefox
    networks:
      robottestsnw: {}
    depends_on:
      - hub
    shm_size: '2g'
    environment:
      HUB_PORT_4444_TCP_ADDR: hub
      SCREEN_WIDTH: 1920
      SCREEN_HEIGHT: 1080
      HUB_HOST: hub

  robottests:
    build: .
    networks:
      robottestsnw: {}
    depends_on:
      - chrome
      - firefox

networks:
  robottestsnw:
    driver: bridge

Dockerfile

# Dockerfile

FROM sgrio/java-oracle

RUN apt-get update
RUN apt-get install -y maven

# Copy test project files to the image folder
COPY . /frontend-integration-tests

# Make the folder as a working directory
WORKDIR /frontend-integration-tests

# Install the test project libraries
RUN mvn package

Answer 1

docker-compose up

它以依赖关系的顺序启动服务，关于停靠-合成-构建不确定。也许你的端口，网络名被定义错了：

hub:
image: selenium/hub
networks:
 - robottestsnw
ports:
 - 4444:4444
