Product Overview

containerd

Description: containerd is an open source container runtime that manages the complete container lifecycle of its host system. It is designed to be lightweight and portable to support container execution on a range of operating systems and platforms.

Docker

Description: Docker is an open platform for developing, shipping, and running applications. It allows developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.
