Πώς γίνεται η διαδικασία ανάπτυξης (deploy) της εφαρμογής;

The automated deployment process includes the following steps:

1. Retrieving the latest version of the code: Usually, a version control system (e.g., Git) is used to pull the latest changes from the repository.

   # Example Git command to fetch the latest changes
   git pull origin main
   

2. Installing dependencies: If the project uses a dependency manager (e.g., Composer), a command is run to install or update libraries.

   // Example Composer command
   composer install --no-dev --optimize-autoloader
   

3. Building the frontend (if applicable): If a frontend bundler (e.g., Webpack, Gulp) is used, a command is executed to build static resources.

   # Example NPM build command
   npm run build
   

4. Database migrations: Scripts are executed to adjust the database structure to the current version of the application.

   # Example command to run migrations
   php artisan migrate --force # Laravel
   

5. Clearing cache and warm-up: The framework cache and data are cleared, and preloading is done if necessary.

   // Example commands to clear cache
   php artisan cache:clear # Laravel
   php artisan config:cache
   php artisan route:cache
   php artisan view:cache
   

6. Creating symbolic links and setting permissions: Necessary symbolic links and permissions to files and directories are configured.

   # Example command to set permissions
   chmod -R 755 storage
   

7. Switching the active version: If a "zero downtime" approach is used (e.g., creating a symbolic link current to the new build), the switch is made.

8. Restarting services (if necessary): If the application requires restarting the web server or queue workers, the appropriate command is executed.

   # Example command to reload PHP-FPM
   sudo systemctl reload php-fpm.service
   

This process is usually automated with scripts or specialized deployment tools (e.g., Capistrano, Deployer, GitLab CI/CD, Jenkins).
