What it is and what it does
dump-env is a command-line tool that generates .env files by reading an .env.template file and overlaying environment variables that match one or more specified prefixes. It has no external dependencies and runs as a pure Python utility. The tool is designed to simplify CI/CD workflows—particularly Docker image builds—where secrets and configuration need to be injected from CI provider environment variables without manual encryption/decryption logic.
The typical workflow is: define a template with default or placeholder values, set prefixed environment variables in your CI system (e.g., SECRET_ENV_DATABASE_URL), and run dump-env to merge them. The tool can enforce strict validation (fail if required variables are missing), support multiple prefixes, and optionally disable value quoting for compatibility with linters like dotenv-linter.
Use it for
- Generate .env files in Docker builds by reading CI secrets prefixed with a convention like SECRET_ENV_.
- Enforce that all required environment variables are present before deploying, using the --strict flag.
- Merge multiple sources of configuration: a template for defaults and environment-specific overrides from CI.
- Create .env files in GitLab CI, GitHub Actions, or Travis CI without custom shell scripting.
- Validate that template variables are defined in the environment before exporting to .env.
