Docker Desktop Require a New WSL Kernel Version

Docker Desktop is a powerful tool that allows developers to build, package, and distribute applications as lightweight containers. It provides an easy-to-use interface to manage containers, images, and networks. However, there are times when Docker Desktop requires a new WSL (Windows Subsystem for Linux) kernel version to function properly. In this article, we will explore what this means and how to resolve it.

Understanding WSL and Docker Desktop

WSL is a compatibility layer in Windows that enables users to run native Linux binaries. It provides a Linux-compatible kernel interface that allows Linux programs to run on Windows. Docker Desktop leverages WSL to create a Linux environment where it can run containers efficiently.

The Need for a New WSL Kernel Version

Docker Desktop requires specific features and capabilities from the underlying WSL kernel to function optimally. In some cases, an update to Docker Desktop may introduce new features that rely on a newer version of the WSL kernel. When this happens, Docker Desktop will prompt you to update the WSL kernel to ensure compatibility.

Updating the WSL Kernel

To update the WSL kernel, follow these steps:

  1. Open a PowerShell terminal with administrator privileges.
  2. Run the following command to install the WSL kernel update package:
wsl --update
  1. Wait for the update to complete.
  2. Restart your computer to apply the changes.

Once the WSL kernel update is installed, Docker Desktop should be able to function properly with the latest features and improvements.

Example Use Case

Let's consider a scenario where you want to run a containerized application that requires the latest version of Docker Desktop. However, when you try to start Docker Desktop, you receive an error message stating that a new WSL kernel version is required.

To resolve this issue, you can follow the steps mentioned earlier to update the WSL kernel. After the update, Docker Desktop will be able to leverage the new features and capabilities of the updated WSL kernel to run the containerized application seamlessly.

Conclusion

In conclusion, Docker Desktop may require a new WSL kernel version to ensure compatibility with the latest features and improvements. By following the steps mentioned in this article, you can easily update the WSL kernel and enable Docker Desktop to run smoothly. Remember to restart your computer after the update for the changes to take effect.
