kooldev/php repository overview
Description
PHP Docker images focused on Laravel applications. They're intended for kool.dev, but can fit other PHP use cases.
The images with Nginx include h5bp/server-configs-nginx with a hand picked set of configuration active by default. So if you want to change or add a new server configuration you can include h5bp/... as you see fit.
Usage
Simplest example:
About composer
All images currently ship out with Composer 2.x as the default version. If for some reason you still need to use Composer 1.x and cannot make the upgrade, we still ship a
composer1in the images PATH as well, which is latest Composer 1.x version. Feel free to use it while you prepare to move to 2.0.
Available Tags
The image built is kooldev/php which has a bunch of tags available:

Contributing
Update images with templates
You should change fwd-template.json for configuration and template folder for the actual base templates.
After any changes, we need to run kool run template to parse the templates and generate all versions folder/files.
Testing and publishing
Run bash scripts/test-image.sh 8.5 to test a locally built image (replace the tag for other variants). CI uses the same script for every image, building base images before their nginx and node variants so tests use the local base rather than a published tag.
Pull requests build and test without publishing or accessing secrets. Pushes to master, weekly scheduled runs, and manual runs on master also publish multi-architecture images, with base images published before derived images.
Repository secrets:
DOCKER_USERNAMEandDOCKER_PASSWORD: Docker Hub credentials for publishing images and syncing this README.DISPATCH_TOKEN: token with access to the downstream repositories and permission to send repository dispatch events (fine-grained tokens need Contents write). Without it, CI publishes images but warns and skips downstream builds.
