The Windows Subsystem for Linux (WSL) is a feature of the Windows 10 Spring Update (2018) which allows users to run Linux-based programs on a Windows 10 computer. This means that users can access a wide range of Linux-based programs, such as command-line tools and software development tools, without the need to install a separate Linux-based operating system.
One of the most common questions related to the Windows Subsystem for Linux is whether it allows users to run Docker on it. Docker is a popular open-source containerization platform which enables developers to package applications into lightweight, portable, and self-sufficient containers which can be run on any platform.
The answer is yes, the Windows Subsystem for Linux does allow users to run Docker on it. To use Docker on WSL, users need to install the Docker Engine - Community package from the Microsoft Store. This package provides the Docker CLI, the Docker daemon, and the Docker Compose tool. Once installed, users need to start the Docker daemon by running the dockerd command in the Windows command prompt.
Once the Docker daemon is running, users can use the Docker CLI to interact with the Docker daemon. This allows users to pull images from the Docker Hub, build images, run containers, and manage images and containers. Furthermore, users can use the Docker Compose tool to create and manage multi-container applications.
In conclusion, the Windows Subsystem for Linux does allow users to run Docker on it. However, users need to install the Docker Engine - Community package from the Microsoft Store and start the Docker daemon before they can begin using Docker. Furthermore, users need to have a good understanding of how Docker works and be familiar with the Docker CLI and the Docker Compose tool.
