WORKDIR doesn't work when running docker-compose run on Windows - docker

Question

It looks like the WORKDIR inside my Dockerfile doesn't work. I'm trying this on Windows 10. The same works perfectly on Mac.
Here are my project files:
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
The tests/DockerImages/testRunner folder has only this 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
If I run docker-compose -f docker-compose.yml run test_runner /usr/local/bin/php tests/Tools/generate-stub-map in cmd.exe in the same directory where docker-compose.yml lies, I would get:
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
However, if I run the same using -w: docker-compose -f docker-compose.yml run -w /opt/project/phpstorm-stubs test_runner /usr/local/bin/php tests/Tools/generate-stub-map - that would work. Output:
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...
I can see here that -w is outdated and I should use --project-directory instead, but doesn't work also:
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.
I've tried to look for something related at docker/compose github issues but found none.

Any help with this is much appreciated.

Answer 1

Sounds like you built test_runner image once using Dockerfile of previous version without WORKDIR parameter and trying to re-run container using this outdated image.
You have to remove image manually or force rebuild it using docker-compose build (or docker-compose up --build) instead of docker-compose run
Also this link may be helpfull

Answer 2

WORKDIR from dockerfile corresponds to working_dir in compose file https://docs.docker.com/compose/compose-file/#working_dir
Try to use
test_runner:
build: tests/DockerImages/testRunner
working_dir: /opt/project/phpstorm-stubs
volumes:
- .:/opt/project/phpstorm-stubs

Answer 3

You have to understand the different path of your whole project.
Location of your docker file C:\Projects\phpstorm-stubs\
Location of base of your project /opt/project/phpstorm-stubs so the exact whole path to your project base in reality is C:\Projects\phpstorm-stubs\opt\project\phpstorm-stubs and so the files it is trying to find is actually at C:\Projects\phpstorm-stubs\opt\project\phpstorm-stubs\usr\local\bin\php tests\Tools\generate-stub-map
So once you used the -f docker-compose.yml it by default thinks that your whole project is at C:\Projects\phpstorm-stubs\ but when you use it with -w /opt/project/phpstorm-stubs it knows that base of your project path is here so it knows that tests/Tools/generate-stub-map is further ahead of it.
And lastly --project-directory requires the whole path from the base of current drive
To sum up my answer you need to use command
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
