Deconstructing an advanced .gitlab-ci.yml file

Now that we've configured GitLab to run continuous integration and continuous deployment with our example project, it's worth exploring a more advanced .gitlab-ci.yml file and breaking it down to make sure that we understand what all of the components do. To this end, here's an example file that uses more jobs and more advanced parameters:

image: bitnami/laravel:latest

services:
  - postgres:9.6

variables:
  POSTGRES_DATABASE: postgres
  POSTGRES_PASSWORD: password
  DB_HOST: postgres
  DB_USERNAME: root

stages:
  - test
  - package
  - deploy

php_unit_test:
  stage: test
  script:
    - cp .env.example .env
    - composer install
    - php artisan key:generate
    - php artisan migrate
    - vendor/bin/phpunit
  cache:
    key: composer
    paths:
      - vendor/

js_unit_test:
  stage: test
  script:
    - npm install
    - npm run test
