WORKDIR在Windows上运行停靠-编写运行时不工作

Question

看起来我的Dockerfile中的WORKDIR不起作用。我正在Windows 10上试用这个，在Mac上也是如此。

以下是我的项目文件: docker-compose.yml：

version: '3'
services:
  php_under_test:
    build: tests/DockerImages/${PHP_VERSION}
    volumes:
      - .:/opt/project/phpstorm-stubs
  test_runner:
    build: tests/DockerImages/testRunner
    volumes:
      - .:/opt/project/phpstorm-stubs

tests/DockerImages/testRunner文件夹只有此Dockerfile：

FROM php:8.1-apache

RUN echo 'memory_limit = 1024M' >> /usr/local/etc/php/conf.d/docker-php-memlimit.ini
COPY --from=composer /usr/bin/composer /usr/bin/composer

RUN apt-get update && apt-get -y install git zip unzip

WORKDIR /opt/project/phpstorm-stubs

如果我在docker-come.yml所在的目录中在cmd.exe中运行cmd.exe，我将得到：

C:\Projects\phpstorm-stubs>docker-compose -f docker-compose.yml run test_runner /usr/local/bin/php tests/Tools/generate-stub-map
WARNING: The PHP_VERSION variable is not set. Defaulting to a blank string.
Creating phpstorm-stubs_test_runner_run ... done
Could not open input file: tests/Tools/generate-stub-map
ERROR: 1

但是，如果我使用-w：docker-compose -f docker-compose.yml run -w /opt/project/phpstorm-stubs test_runner /usr/local/bin/php tests/Tools/generate-stub-map运行相同的程序，那就可以了。输出：

C:\Projects\phpstorm-stubs>docker-compose -f docker-compose.yml run -w /opt/project/phpstorm-stubs test_runner /usr/local/bin/php tests/Tools/generate-stub-map
WARNING: The PHP_VERSION variable is not set. Defaulting to a blank string.
Creating phpstorm-stubs_test_runner_run ... done
Parsing "/opt/project/phpstorm-stubs/tests/Tools/../../aerospike/aerospike.php"
Parsing "/opt/project/phpstorm-stubs/tests/Tools/../../aerospike/Bytes.php"
etc...

我可以看到这里，-w已经过时了，我应该使用--project-directory，但也不起作用：

C:\Projects\phpstorm-stubs>docker-compose -f docker-compose.yml --project-directory /opt/project/phpstorm-stubs run test_runner /usr/local/bin/php 
tests/Tools/generate-stub-map
WARNING: The PHP_VERSION variable is not set. Defaulting to a blank string.
ERROR: build path C:\opt\project\phpstorm-stubs\tests\DockerImages either does not exist, is not accessible, or is not a valid URL.

我试图在docker/compose github问题上寻找一些相关的东西，但没有发现任何问题。

docker version输出：

这方面的任何帮助都是非常感谢的。

Answer 1

听起来，您一次构建test_runner映像时，使用的是以前版本的Dockerfile，没有WORKDIR参数，并且尝试使用这个过时的映像重新运行容器。

您必须手动删除图像，或者使用docker-compose build (或docker-compose up --build)而不是docker-compose run强制重建图像。

Answer 2

来自dockerfile的WORKDIR对应于复合文件目录中的working_dir

试着使用

  test_runner:
    build: tests/DockerImages/testRunner
    working_dir: /opt/project/phpstorm-stubs
    volumes:
      - .:/opt/project/phpstorm-stubs

Answer 3

你必须了解你整个项目的不同路径。

停靠文件C:\Projects\phpstorm-stubs\的位置

项目/opt/project/phpstorm-stubs的基本位置，所以在现实中，到项目库的确切的整个路径是C:\Projects\phpstorm-stubs\opt\project\phpstorm-stubs，所以它试图查找的文件实际上位于C:\Projects\phpstorm-stubs\opt\project\phpstorm-stubs\usr\local\bin\php tests\Tools\generate-stub-map。

因此，一旦您使用了-f docker-compose.yml，它默认认为您的整个项目位于C:\Projects\phpstorm-stubs\，但是当您将它与-w /opt/project/phpstorm-stubs一起使用时，它知道您的项目路径的基础在这里，所以它知道tests/Tools/generate-stub-map在它前面。

最后，--project-directory要求从当前驱动器的基座到整个路径。

要总结我的答案，您需要使用命令

docker-compose -f docker-compose.yml --project-directory /Projects/phpstorm-stubs/opt/project/phpstorm-stubs run test_runner /usr/local/bin/php tests/Tools/generate-stub-map
