containerd is a container runtime, originally written by Docker engineers. Solomon Hykes, the founder of Docker has blogged about it in 2016.

Today Docker is spinning out its core container runtime functionality into a standalone component, incorporating it into a separate project called containerd, and will be donating it to a neutral foundation early next year. This is the latest chapter in a multi-year effort to break up the Docker platform into a more modular architecture of loosely coupled components.

I've been a reviewer since 2021 and committer since 2022.
