无法将文件从docker-compose挂载复制到主机 [英] Unable to copy file from docker-compose mount to host

问题描述

我无法将Selenium测试生成的文件复制到安装到主机的docker容器内的文件夹中。

I am unable to copy a file generated by my Selenium tests in a folder inside docker container mounted to host machine.

这是我的撰写文件的样子

Here is how my compose file look like

  selenium:
    image: 'selenium/standalone-chrome'
    expose:
      - "4444"
  tests:
    build:
      context: ./tests
      dockerfile: Dockerfile
    depends_on:
      - selenium
      - web
    volumes:
      - /testResultsReport:/testResultsReport

这是我的目录结构的样子

This is how my directory structure looks like.

\
 - docker-compose.yml
 - build scripts
 - tests
   - testResultsReport
   - Test scripts

testResultsReport内部生成的文件名运行docker-compose时的文件夹是 TestResultsReport.HTML

Name of the file generated inside testResultsReport folder when running docker-compose is TestResultsReport.HTML

因为我的测试在端口<$上的硒服务器中运行c $ c> 4444 ，sho我可以把音量放在那里吗？我试图这样做，但仍然没有将我的HTML文件复制到主机上？
我确认我在compose之外运行测试时生成了html文件。

As my tests are running inside selenium server on port 4444, should I mount my volume there? I tried doing that to but still not getting my html file copied to host machine? I confirmed that my html file is generated when i run my tests outside compose.

我也尝试过./testResultsReport，但是它在根目录中添加了一个名为name的文件夹的testResultsReport，什么也没做。因此，我使用了./tests/testResultsReport，但仍未获取文件。

I also tried ./testResultsReport however it added a folder in root with name of testResultsReport and did nothing. So I used ./tests/testResultsReport but still not getting file.

推荐答案

使用正确的文件夹和绝对路径进行工作。谢谢@chrisz

Worked by using right folder and absolute path. Thanks @chrisz

selenium:
    image: 'selenium/standalone-chrome'
    expose:
      - "4444"
  tests:
    build:
      context: ./tests
      dockerfile: Dockerfile
    depends_on:
      - selenium
      - web
    volumes:
      - ./tests/testResultsReport:/tests/testResultsReport
