Key Notes

• When managing Kubernetes resources with Kustomize, your configuration is defined in a kustomization.yaml file. While the ApiVersion and Kind properties are technically optional—since Kustomize assigns default values—they are essential for maintaining stability, especially when updates might introduce breaking changes.
• Below is an example of a properly configured kustomization.yaml file:
• kustomize.config.k8s.io/v1beta1
• nginx-service.yaml
• Hardcoding the ApiVersion and Kind values is a best practice that helps ensure compatibility and prevents unexpected behavior as new versions of Kustomize are released.
