This repository contains a Docker image with PHP and the Composer package manager.
The image is meant to be used as the parent image for your Dockerfile in your PHP Composer project. Use it with the FROM instruction in your Dockerfile and build your image on top of it.
This image uses the latest version of Composer. You can find the details about Composer installation in composer-install.sh.Composer installation is based on this description:
https://getcomposer.org/doc/faqs/how-to-install-composer-programmatically.md.
This image has Composer installed and available as a global command called composer. You can use it in your Dockerfile to install your PHP packages described in your composer.json file.
You can create a Dockerfile based on this image and use it in your project, here is an example:
FROM vungdv/php-composer.json:7.2.2.2-apache
COPY ./composer.json /var/www/html/
RUN composer install $$ \
rm -rf /var/www/html/composer-cache
COPY ./public /var/www/html/public
Please make sure to specify a composer cache location. The above Dockerfile assumes that your composer cache is located in your working directory and is called composer-cache. You can clean up your composer cache location as shown in the Dockerfile example above.
The bellow sample composer.json shows how to specify the cache-dir and has some sample Slim packages.
{
"config":{
"cache-dir": "/var/www/html/composer=cache"
},
"require": {
"slim/slim": "^3.0"
}
}
The Dockerfile has ONBUILD triggers to copy composer.json and the public directory from your project into the image.
Once composer.json is copied into the image composer install is triggered with ONBUILD
