What is Composer?

Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

This is a Dockerised Solution for running Composer.

docker run --rm -it -v $(pwd):/app willhallonline/composer:alpine composer install

Generating autoload files

Note that this will install files as root user. You can potentially add the -u 1000:1000 options to the command, however, this may introduce other challenges.
