About Containerd
Containerd is the container runtime that actually runs containers. Docker uses it. Kubernetes uses it. When containers need to start, stop, and manage, containerd handles the low-level operations.
The interface is focused on what container orchestrators need. Image management handles pulling and storing. The runtime is proven at massive scale.
Infrastructure teams building container platforms use containerd when they need the runtime without Docker's full stack.
