1Which Docker file is recommended for defining services of a Symfony application (PHP-FPM, Nginx, PostgreSQL) in local development?
Which Docker file is recommended for defining services of a Symfony application (PHP-FPM, Nginx, PostgreSQL) in local development?
Resposta
Docker Compose (docker-compose.yml or compose.yaml) allows defining and orchestrating multiple Docker containers. For Symfony, you typically define a PHP-FPM service to run the code, Nginx as web server, and PostgreSQL for the database. This approach ensures an identical development environment for the whole team and similar to production.
2How to correctly define a DATABASE_URL environment variable in Symfony to be different in development and production?
How to correctly define a DATABASE_URL environment variable in Symfony to be different in development and production?
Resposta
Symfony uses the .env file for default values and .env.local for local overrides (not versioned). In production, it's preferable to define variables directly via system environment or server secrets. The .env.local file is never committed and allows each developer to have their own configurations.
3Which Symfony command allows managing secrets securely in production (API keys, passwords)?
Which Symfony command allows managing secrets securely in production (API keys, passwords)?
Resposta
Symfony Secrets allows storing sensitive data in an encrypted manner. Secrets are stored in config/secrets/ and encrypted with a key. The secrets:set command adds a new secret, and only the environment with the decryption key can read the values. This is the recommended method for production credentials.
