Answer
containerd provides slim, fast, Kubernetes-native runtime integration.
Quick Answer
Docker's runtime (originally dockerd → runc) was tightly coupled. Kubernetes standardized the Container Runtime Interface (CRI), allowing any CRI-compliant runtime. containerd (Docker's own) and CRI-O emerged as lighter, purpose-built runtimes for Kubernetes — no docker CLI overhead, just the container lifecycle management Kubernetes needs.
