: A simplified GUI where you can create a CPK file by dragging and dropping a folder .

These tools typically allow you to:

CRI file system tools are more than just background utilities; they are the connective tissue of modern cloud-native architecture. By decoupling the runtime from the orchestrator and providing a standardized way to manage storage layers, they have enabled a more stable, scalable, and diverse container ecosystem. As Kubernetes continues to evolve, the refinement of these file system links will remain a cornerstone of infrastructure reliability.
