== containerd Proposal

*Name of project:* containerd

*Description*

containerd is a widely used container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, and low-level storage, etc..

containerd is designed to be embedded into a larger system, rather than being used directly by developers or end-users. containerd will serve as a core container runtime for the CNCF ecosystem.

*Statement on alignment with CNCF mission*:

containerd is the most widely used container runtime, which is a critical building-block for cloud-native computing and is highlighted in the [CNCF charter](https://www.cncf.io/about/charter/). It intends to provide a container runtime for projects like Docker and Kubernetes that provide execution platforms for cloud-native applications.
