Industry Scenarios

Practical Use Cases for Kubernetes ConfigMap Generator

Decoupling Configuration from Container Images

Inject environment variables and application configuration files into pods without rebuilding container images.

Mounting Config Files as Volumes

Store entire configuration files (`nginx.conf`, `redis.conf`) in a ConfigMap and mount them directly into pod directories.
