A templating engine generates rendered Kubernetes resources by replacing variables in reusable YAML definitions. It lets teams use different parameters for different environments without maintaining duplicate files. section 2.1.2
Template engines address practical application-packaging problems:
- Reuse one resource definition across testing and production environments. section 2.1.2
- Replace environment-specific values such as database URLs during rendering. section 2.1.2
- Reduce the maintenance burden caused by accumulating near-duplicate YAML files. section 2.1.2
- Consider Kubernetes-focused or YAML-focused tools such as Kustomize and Carvel YTT alongside package managers. section 2.1.2
Figure 2.2 Templating engines render YAML resources by replacing variables.
Visualizes how variables become concrete YAML resources through rendering. section 2.1.2
