Docker Desktop Requires a New WSL

Introduction

Docker Desktop is a popular tool used by developers to create, deploy, and manage applications using containers. Recently, Docker Desktop announced that it will require a newer version of Windows Subsystem for Linux (WSL) to run effectively. In this article, we will explore what WSL is, why Docker Desktop requires a newer version, and how to upgrade WSL to meet the new requirements.

What is WSL?

WSL is a compatibility layer provided by Microsoft to run Linux binary executables natively on Windows 10 and Windows Server 2019. It allows developers to use their favorite Linux tools and commands on a Windows machine, enabling a seamless development experience across different operating systems.

Why Docker Desktop Requires a Newer WSL?

The newer version of WSL provides better performance, compatibility, and features for running Linux applications on Windows. Docker Desktop leverages the capabilities of WSL to create a more efficient containerized environment. By requiring a newer WSL version, Docker aims to enhance the overall user experience and ensure compatibility with the latest features and updates.

Upgrading WSL

To upgrade WSL to meet the requirements of Docker Desktop, follow these steps:

  1. Open PowerShell as an administrator.
  2. Run the following command to check the current WSL version:
wsl -l -v
  1. If the version is older than WSL 2, you will need to upgrade to WSL 2. Run the following command to set WSL 2 as the default version:
wsl --set-default-version 2
  1. Restart your computer to apply the changes.

Sequence Diagram

Here is a sequence diagram illustrating the process of upgrading WSL for Docker Desktop:
