{{-- 

A commented Laravel Envoy (https://laravel.com/docs/master/envoy) script that deploy from private GitLab repo
Tested on Laravel 5.8 and Laravel Envoy 1.5 and Ubuntu 16.04 LTS
Inspired by https://docs.gitlab.com/ee/ci/examples/laravel_with_gitlab_and_envoy/

Running command: envoy run deploy

Prerequisites:
✓ Laravel prerequisites are installed on @servers https://laravel.com/docs/master/installation#server-requirements
✓ $releases_dir, $app_dir, $data_dir are available at @servers
✓ @servers user is a sudoer that requires NO password
✓ @servers runs web server (apache/nginx) using www-data
✓ @servers SSH public key has been registred as Deploy Keys in GitLab https://docs.gitlab.com/ee/api/deploy_keys.html (required unless using public repo)
✓ @servers has registered GitLab as known server (do git clone from there once) 
✓ (optional) Supervisord is installed. Needed only queue worker setup is activated
✓ (optional) Laravel Passport is one of dependency https://laravel.com/docs/master/passport

Optional features (activate by uncomment corresponding parts):
