GItlab ci: Composer cache permission denied

[rophini92]

Hi,

We have an issue with using the image using Gitlab-ci. We're migrating from the edbizarro/gitlab-ci-pipeline-php image.

Expected Behavior

Composer install should install all the packages. It works if we add the --no-cache flag to composer install.

Current Behavior

Composer fails installing, gives the following error while downloading the packages:

Failed to download nunomaduro/collision from dist: /cache/files/nunomaduro/collision does not exist and could not be created: 
    Now trying to download from source
  - Syncing nunomaduro/collision (v8.1.1) into cache
In Cache.php line 201:
  copy(/cache/files/symfony/polyfill-intl-grapheme/f2ff520717c3b4b0b6f235bd92  
  376b0e57d129tyc.zip): Failed to open stream: Permission denied   

Your Environment

These are the settings in our gitlab-ci file.

build:composer:
  image: thecodingmachine/php:8.2-v4-cli
  stage: build
  only:
    - master
    - main
    - development
    - dev
  script:
    - composer install

Thanks!

I do not understand why composer in your environment store his cache to /cache/ instead of /home/docker/.cache/composer . I do not reproduice it with a regular docker run process.
I recommand you to check your environments variables and gitlab-ci runner configuration.
