What is WSL 2+Docker?
WSL 2+Docker is a powerful combination of two technologies that enable developers and administrators to run Linux distributions and Docker containers directly on Windows 10 and Windows Server 2019. WSL (Windows Subsystem for Linux) is a compatibility layer that allows Linux binaries to run on Windows, while Docker is a containerization platform that enables the creation, deployment, and management of containers. By combining WSL 2 and Docker, users can leverage the strengths of both technologies to create a seamless and efficient development and deployment environment.
