Stack: TypeScript (Zod), Python (Pydantic), Docker, Kubernetes

Overview

Patterns for managing application settings across environments (Dev, Staging, Prod) securely and reliably.

Core Principles

1. 12-Factor App: Store config in the environment.
2. Strict Validation: Fail fast if config is invalid at startup.
3. Secret Separation: Never commit secrets; use Vault/KMS/Secrets Manager.
4. Type Safety: Treat configuration as typed objects, not raw strings.
