说明
containerd is an industry-standard container runtime that manages the complete container lifecycle on a host system. It handles image transfer and storage, container execution and supervision, low-level storage, and network attachments. As a daemon, containerd provides a gRPC API for higher-level tools like Docker, Kubernetes, and nerdctl to interact with. It supports OCI (Open Container Initiative) images and runtime specifications, ensuring compatibility across the container ecosystem. containerd is designed to be embedded into larger systems rather than used directly by end users. Kubernetes uses containerd as its container runtime through the CRI (Container Runtime Interface), and Docker uses it as its core runtime engine.
