Improve installation script

[nicolashuber]

Today the installation process is written on bash script. It's difficult to maintain a complex script, it would be interesting to find a way to use a more modern programming language to run the installation.

I suggest use the The Console Component from Symfony. With a PHP we can create a more robust script. But on the one hand, PHP becomes a prerequisite together with Docker.

The great challenge is that the script should orchestrate all related containers. With this in mind, I thing the script must call the exec PHP function and call docke-compose.

To abstract we could have the following classes:

Docker.php:

<?php
namespace App\Docker;
class Docker {
    public function up($service, $args = null) {
        return exec('docker-compose -d up ' . $service . ' ' . $args . ' 2>&1');
    }
    public function run($service, $args = null) {
        return exec('docker-compose run --rm ' . $service . ' ' . $args . ' 2>&1');
    }
    public function pull() {
        return exec('docker-compose pull 2>&1');
    }
    public function build() {
        return exec('docker-compose build 2>&1');
    }
}

Yarn.php:

<?php
namespace App\Docker;
class Yarn extends Docker {
    public function install() {
        return $this->run('node', 'yarn');
    }
}

Another approach would be to use access the Docker Engine API, like the reactphp-docker library.
