Managing Environment Configurations

Overview

Manage application configurations across development, staging, and production environments using .env files, Kubernetes ConfigMaps/Secrets, SSM Parameter Store, and cloud-native configuration services. Enforce consistency, prevent configuration drift, and implement safe promotion workflows between environments.

Prerequisites

• Access to all target environments (dev, staging, production)
• Configuration management tool or pattern identified (dotenv, ConfigMaps, SSM, Consul)
• Version control for configuration files (separate repo or encrypted in application repo)
• Encryption tool for sensitive values (sops, age, sealed-secrets, or cloud KMS)
• Understanding of which values differ between environments vs. which are shared
