Docker Desktop Windows Containers Not Enabled

Introduction

When working with Docker on Windows, you may encounter the issue where Windows containers are not enabled in Docker Desktop. This can prevent you from running Windows containers and may cause confusion.

In this article, we will discuss why Windows containers may not be enabled, how to enable them, and provide some code examples to help you get started.

Why Windows Containers Not Enabled

By default, Docker Desktop on Windows runs Linux containers. This means that Windows containers are not enabled out of the box. To enable Windows containers, you need to switch the Docker Desktop configuration to use Windows containers.

How to Enable Windows Containers

To enable Windows containers in Docker Desktop, follow these steps:

  1. Right-click on the Docker Desktop icon in the system tray.
  2. Click on "Switch to Windows containers" in the context menu.
  3. Docker Desktop will restart and switch to using Windows containers.

Code Examples

Here are some code examples to help you get started with Windows containers in Docker.
