## Description
The Configuration Template pattern uses template processors to generate configuration files from templates with data from ConfigMaps. This enables dynamic configuration generation while keeping templates in version control. The processor fills in template variables with values from ConfigMaps before the application starts.


## Use Cases
Use when you need to generate configuration dynamically or when you want to maintain configuration templates with variable substitution.





## Trade-offs


### Advantages

- Dynamic configuration generation

- Templates in version control

- Separates template logic from data

- Supports complex configuration scenarios




### Considerations & Drawbacks

- Requires template processor

- Adds complexity to deployment

- Template maintenance overhead
