Product Overview

Colima

Description: Colima is an open-source tool for running Docker desktop environments in containers. It provides a lightweight and fast way to use Docker and test applications without installing a full VM.

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.
