CI/CD

Description

Minimal PHP Docker image focused on Laravel applications. It's use is intended for kool.dev, but can fit in any other PHP use-case.

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:

asciicast

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 composer1 in 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.

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.
