Production-settings May 2026

This allows you to move the same Docker image through Testing, Staging, and Production without changing a single line of code—only the environment variables change. 5. Security Headers and HTTPS

Set up endpoints (e.g., /health/ ) that return a 200 OK status only if the app, database, and cache are all functional. Load balancers use these settings to know when to pull a "sick" server out of rotation. 4. The "Environment" Boundary production-settings

Production is the only place where strict web security is non-negotiable. Your settings should enforce: This allows you to move the same Docker

Instead of opening a new connection for every request—which is slow and resource-heavy—use a pooler like PgBouncer or built-in framework pooling to keep a set of "ready-to-use" connections. Load balancers use these settings to know when

The most robust way to manage production-settings is via . Following the 12-Factor App methodology, your code should be agnostic of its environment.

In development, convenience is king. You want verbose error logs, open ports, and easy access. In production, every convenience is a potential vulnerability.
