Deploy laravel using gitlab ci in VPS WITHOUT DOCKER

Finally after some research in gitlab itself and trials, I figured it out. I used gitlab-runner which executes the jobs in .gitlab-ci.yml And wrote this yml file for the very beginning:

before_script:
  - echo "Before script"
  - cd /var/www/html/project
building:
  stage: build
  script:
    - git pull origin develop
    - composer install
    - cp .env.example .env
    - php artisan key:generate
    - php artisan migrate --seed
    - sudo chown -R my-user:www-data /var/www/html/project/
    - find /var/www/html/project -type f -exec chmod 664 {} \;
    - find /var/www/html/project -type d -exec chmod 775 {} \;
    - chgrp -R www-data storage bootstrap/cache
    - chmod -R ug+rwx storage bootstrap/cache
testing:
  stage: test
  script:
    - php ./vendor/bin/phpunit
deploying:
  stage: deploy
  script:
    - echo "Deployed"

If you have a better solution, you can write here.
