ConfigMaps & Secrets for Configuration

Managing application configuration and sensitive data can be tricky, especially in dynamic environments like Kubernetes.

Hardcoding values into images makes them less reusable. Storing secrets directly in Git is a security risk.

Kubernetes offers two powerful resources to solve these challenges: ConfigMaps and Secrets.

A ConfigMap is an API object used to store non-sensitive configuration data in key-value pairs.

Think of it as a central place for settings like database hostnames, logging levels, or API endpoints.

• Separates configuration from application code.
• Allows easy updates without rebuilding images.
• Can be consumed as environment variables or mounted files.
