Answer
Use .env files, secrets managers, or environment-specific configs. Avoid hardcoding credentials.
Quick Answer
Use environment variables for secrets and environment-specific values. Use config files for non-secret settings. Have separate .env files per environment. Never commit real secrets to git. Load config at startup and cache it. Use a config service class to centralize access. In Kubernetes, use ConfigMaps for config and Secrets for sensitive values. Validate required config on app boot.
