Hierarchical Environment Variable Management

I still spend too much time managing environment variables!

The “Twelve-Factor” methodology prescribes that cloud-native applications should be configured via environment variables.

This recommendation separates configuration from code, which is essential for scalability and security. But it also results in an extensive array of environment variables.

Having to manage these variables for test, integration, end-to-end, and production environments becomes a daunting task. Often, these variable sets intersect. For instance, while Github credentials might be consistent across all environments, AWS accounts may vary.
