Introduction
Docker Desktop is a popular containerization platform that simplifies the process of developing, testing, and deploying applications. One of the requirements to run Docker Desktop is the Windows Subsystem for Linux (WSL) or WSL 2. However, some users might encounter issues while trying to get Docker Desktop running on WSL, especially when updating from WSL to WSL2. In this article, we will discuss the troubleshooting steps to help you resolve common issues during the installation and update process of Docker Desktop on WSL and WSL2.
Prerequisites
Before we dive into the troubleshooting steps, make sure you meet the following requirements:
- Windows 10 version 2004 or later
- Docker Desktop for Windows
- Microsoft Virtual Platform for Integrated Syscalls (optional for WSL2)
Update WSL: Run 'wsl --update'
The first step is to update your existing WSL installations using the 'wsl --update' command:
C:\> wsl --update
If the update is successful, you will see a message indicating that the update is complete:
Installing new WSL 2 virtual machine based on C:\\.wsl2...
Installing related components starting with this:
Running: C:\Windows\System32\wsl.exe --install
Downloading Windows Subsystem for Linux files...
Installing packages for WSL 2...
The installation is complete.
Enable WSL2: Run 'wsl --set-default-version 2'
After updating WSL, you need to enable WSL2 for your user:
C:\> wsl --set-default-version 2
You should see a message confirming that WSL2 has been enabled for your user:
Your default WSL version has been successfully changed to WSL 2.
Install Docker Desktop
Once WSL2 is enabled, you can install Docker Desktop:
- Download Docker Desktop from the official website: https://docs.docker.com/desktop/windows/install/
