How Kubernetes pulls images, delegates execution to runtimes, and lets Pods request different runtime behavior.
An image is a supply chain artifact. Kubernetes can pull it, but you still own versioning, provenance, size, and rollback behavior.
kubelet does not run containers directly. It talks through the Container Runtime Interface to a runtime such as containerd.
RuntimeClass lets a Pod ask for a different execution environment without changing the application manifest shape.
