Overview

ConfigMaps store configuration data, while Secrets store sensitive information. Both decouple configuration from images, enabling security and flexibility.

<aside> ℹ️ Why It Matters: Understanding ConfigMaps & Secrets is essential for building robust, scalable, and secure modern applications.
