Kustomize enables users to navigate and modify Kubernetes manifests by adding, removing, or altering configuration settings without the necessity of creating forks. It can be utilized as an independent binary or integrated as a built-in feature of kubectl. This tool adopts a strictly declarative methodology for customizing configurations, allowing the management of multiple uniquely tailored Kubernetes settings. Additionally, it is accessible as a standalone binary, making it easy to extend and incorporate into various other services. All artifacts utilized by Kustomize are standard YAML files, which can be easily validated and processed accordingly. Kustomize promotes a workflow that involves forking, modifying, and rebasing, which enhances collaboration and efficiency in managing Kubernetes configurations. By streamlining these processes, Kustomize provides users with a powerful means of maintaining their Kubernetes environments.
