Kustomize - power of customization

What Kustomize is? Kustomize is a configuration management tool built into kubectl for customizing Kubernetes YAML manifests without modifying the original files. It allows users to define a common set of base resources and then layer environment-specific customizations (called overlays) on top. This makes it ideal for managing multiple deployment environments like development, staging, and production. Instead of using templates or variables, Kustomize works by applying transformations directly to Kubernetes-native YAML.
