In their own words
containerd
containerd is a free container runtime for managing a host’s container lifecycle. It handles image transfer and storage, execution, and supervision, and is designed to be embedded in a larger system rather than used directly by developers or end users. It supports OCI images and image push and pull operations, and uses runc by default while allowing other OCI-compliant runtimes. Its built-in CRI plugin can make it the container runtime for a Kubernetes cluster, and it supports registries compliant with the OCI Distribution Specification. The daemon is available for Linux and Windows. Network-interface management and image building are outside containerd’s first-class scope, so higher-level systems or tools handle those jobs. Its ctr command-line tool is intended for development and debugging, without a guarantee of a stable interface or a human-friendly experience. Users typically also need runc and CNI plugins. The plan is free; free plan available, with no free trial.
