.env.dist.local 〈PROVEN ⚡〉

Overwrites the production defaults with safe, standardized local development defaults.

Use comments to explain what each variable does, what values are accepted, and why a developer might want to change it. Conclusion

Before these changes, projects typically used a .env.dist file as a template that was committed to version control, while the actual .env file containing sensitive values was ignored. While functional, this approach had significant limitations—most notably, the lack of clear separation between shared defaults and personal overrides, leading to confusion when developers needed to customize their local environments. .env.dist.local

This file should not be committed to version control with sensitive data. Instead, create a .env.local file (not version controlled) with your actual credentials and settings. The .env.dist.local file serves as a template for setting up your local environment.

The .env.dist.local file is a powerful tool for teams managing complex local mock architectures, heavy Docker workflows, or multi-layered deployment environments. By separating your global configuration templates ( .env.dist ) from your local development templates ( .env.dist.local ), you reduce onboarding friction for new developers while keeping your production baselines clean, explicit, and secure. heavy Docker workflows

The most common and devastating security failure is accidentally committing .env or .env.local files to version control. Once committed, these secrets remain in Git history forever, even if later removed. Even a single accidental git add . followed by git commit can expose database credentials, API keys, and other sensitive information to anyone with repository access.

The idea behind .env.dist.local is to create a template file that contains default values for environment variables, which can then be overridden by a .env.local file. This approach provides several benefits:

In a robust environment configuration system, you typically work with a hierarchy of files. The loading order is key, as later files override the values in earlier ones. A common and comprehensive hierarchy is as follows (with each succeeding file having higher priority):

If your team modifies the local Docker environment—such as changing a local Redis port from 6379 to 6380 —update the .env.dist.local file immediately. This ensures that the next time a teammate pulls the main branch, their template updates automatically. A Typical Setup Example
