: Comment why a variable is needed or what its default value should be.

If you choose to implement this file in your workflow, follow these rules:

: The local override file. It contains machine-specific secrets or configurations (like your personal database password). It is strictly ignored by Git. .env.dist.local

First, developers rename their existing .env.dist file to .env , ensuring this committed file contains only non-sensitive defaults. The previous .env file (which may have contained sensitive values) becomes .env.local and is added to .gitignore . The .gitignore file should include patterns like / .env.local , / .env.local.php , and / .env.*.local .

.env # Shared across all environments .env.local # Your personal machine overrides .env.test # Test environment defaults .env.test.local # Your personal test overrides

DB_HOST=127.0.0.1 DB_USER=myuser_dev DB_PASSWORD=mypassword_dev It is strictly ignored by Git

: Use this file to document variables that are unique to a developer's machine but necessary for the app to run (e.g., LOCAL_DB_PORT=5432 ).

Imagine a development team where everyone uses a shared Docker Compose setup for local development. The local database is always named dev_db , the user is always root , and it always runs on port 5432 .

In the modern software development landscape, managing configuration across multiple environments has become a cornerstone of secure and efficient application deployment. Among the myriad of patterns and practices, the concept of .env.dist.local emerges as a fascinating evolution in environment variable management—a pattern that elegantly balances the need for shareable templates, secure local overrides, and collaborative development workflows. This comprehensive guide explores this powerful pattern, its origins in major frameworks like Symfony and Laravel, and how it can transform your team's approach to configuration management. If you leave .env.dist blank

# Uncomment the line below to use a local DB instead of staging # DATABASE_URL=mysql://root:password@127.0.0.1:3306/my_app Use code with caution.

: Machine-specific, highly private overrides and actual secrets. Never committed to Git. What is .env.dist.local ?

If you put these local defaults into .env.dist , you risk those local values accidentally slipping into production configurations if a pipeline is misconfigured. If you leave .env.dist blank, every single developer has to manually type out the exact same Docker credentials into their personal .env.local .
