.env.python.local (FULL ✯)
– For containerized applications running on Kubernetes, use the Secrets API to mount sensitive configuration as files or environment variables.
Mismanaging environment variables poses a massive security risk. Follow these strict rules to ensure your local configurations remain secure:
Add the following pattern to your project's .gitignore file immediately: .env.python.local
If you want to load variables into a dictionary rather than the system environment, use dotenv_values .
To support a hierarchical loading structure where .env.python.local overrides standard .env files, you must load the most specific files first. The python-dotenv library, by default, will not overwrite an existing environment variable. To support a hierarchical loading structure where
: Committed to version control. This file acts as a template containing non-sensitive default values and empty placeholders for required secrets.
(e.g., Heroku config vars, AWS Lambda environment variables, Azure App Settings). Most modern platforms provide native support for managing environment variables without requiring files on disk. This file acts as a template containing non-sensitive
Wait—why ignore .env as well? Because for maximum security, you should actually commit a .env.example file instead of the real .env . But if you choose to commit a safe .env (without secrets), then only ignore *.local .
if os.getenv('ENVIRONMENT') == 'production': load_dotenv('.env') else: load_dotenv('.env') load_dotenv('.env.local', override=True)
: Contains secrets or personal configurations (machine-specific).
Managing environment variables and configuration files can be a challenge, especially in complex projects. By using .env , .python , and .local files, you can streamline your development workflow and keep sensitive information secure. By following best practices and using libraries like python-dotenv , you can write more robust and maintainable code.
