What is WSL 2+Docker?

WSL 2+Docker is a hybrid infrastructure that combines the Windows Subsystem for Linux (WSL) with Docker, a popular containerization platform. This integration allows developers to run Linux distributions and Docker containers directly on Windows, enabling a seamless development experience. With WSL 2+Docker, users can leverage the strengths of both worlds, utilizing the Windows ecosystem while taking advantage of the flexibility and portability of Linux and containers.

Main Components

The WSL 2+Docker infrastructure consists of two primary components: WSL 2 and Docker Desktop. WSL 2 provides a Linux environment that runs on top of Windows, allowing users to install and run Linux distributions, such as Ubuntu or Debian. Docker Desktop, on the other hand, enables the creation and management of Docker containers, which can be used to package and deploy applications.
