How to Delete a Docker Image on Windows VPS

Introduction

Docker is a popular tool for creating, managing, and deploying containers. If you’re running Docker on a , you may occasionally need to delete unused Docker images to free up space or maintain your environment. This guide will show you how to delete Docker images efficiently.

Step 1: List Docker Images

Before deleting a Docker image, it’s important to identify which images are currently available on your system:

1. Open a terminal or command prompt on your Windows VPS.
2. Run the following command to list all Docker images:

docker images

This will display a table with the image repository, tag, and image ID.

Step 2: Delete a Specific Docker Image

Once you’ve identified the image you want to delete, use the following command:

docker rmi <IMAGE_ID>

Replace <IMAGE_ID> with the actual ID of the image you want to delete (e.g., docker rmi abc123def456).

Step 3: Force Delete an Image

If the image is currently being used by a container, you might encounter an error when trying to delete it. To forcefully remove the image, use:

docker rmi -f <IMAGE_ID>

Be cautious when using the force option, as it will remove the image even if it’s in use.

Step 4: Clean Up Unused Images

You can remove all unused Docker images in one go to free up disk space by running:

docker image prune

To remove all unused images, containers, and networks, use:

docker system prune

Add the -a flag to remove all unused images, including dangling ones:

docker system prune -a

Step 5: Verify Deletion

To ensure the image has been deleted, list the remaining images by running:

docker images

If the image is no longer listed, it has been successfully removed.
