How to Delete a Docker Image on Linux

By Netcloud24

 

 

Docker is a powerful tool that allows developers to build, test, and deploy applications in isolated environments. Over time, you may accumulate unused Docker images, which can take up space on your system. This guide will show you how to safely delete Docker images on a Linux-based system.

Step 1: List Docker Images

Before deleting any Docker images, it’s important to first identify which images are present on your system. To list all Docker images, use the following command in your terminal:

docker images

This will display a table with the repository, tag, image ID, and other details for each Docker image.

Step 2: Delete a Specific Docker Image

To delete a specific Docker image, you need to reference either the image ID or the image name. Use the following command to delete a Docker image:

docker rmi <image-id>

For example:

docker rmi abc123def456

This will remove the Docker image with the ID abc123def456 from your system.

Step 3: Force Delete a Docker Image

If the image is being used by a container, you may encounter an error when trying to delete it. To force the deletion of an image, use the --force option:

docker rmi -f <image-id>

This will forcefully remove the image, even if it’s in use by a container.

Step 4: Remove All Unused Docker Images

Over time, unused or “dangling” images (images not associated with any container) may accumulate. To delete all unused Docker images, run the following command:

docker image prune -a

This will remove all unused Docker images from your system, freeing up valuable disk space.

Managing Docker on a VPS

If you’re running Docker on a VPS server and want to keep your system clean and optimized, deleting unused Docker images is a crucial step. Whether you’re managing a personal project or a production environment, regular maintenance is key to ensuring your VPS runs smoothly.

Docker is a powerful containerization platform that allows you to run applications in isolated environments. Over time, unused Docker images can accumulate and take up valuable disk space. In this guide, we will show you how to delete a Docker image on Linux. Managing Docker images efficiently is essential for optimizing performance, especially on a WindowsVPS, where using dedicated VPS server resources ensures smooth operation.

Step 1: List Docker Images

Before deleting a Docker image, you need to know which images are available on your system. To list all Docker images, use the following command:

docker images

This command will display a list of all available Docker images, along with their image IDs, repository names, and tags. The output will look something like this:


REPOSITORY          TAG         IMAGE ID        CREATED         SIZE
ubuntu              latest      2d696327ab2e    2 days ago      72.9MB
myapp               v1          3b73b0c8f692    1 week ago      118MB

Step 2: Delete a Specific Docker Image

To delete a Docker image, you need to reference the image ID or repository name and tag. To delete an image, use the following command:

docker rmi IMAGE_ID

For example, to delete the ubuntu:latest image from the list above, you would run:

docker rmi 2d696327ab2e

If you want to delete the image using the repository name and tag, run:

docker rmi ubuntu:latest

Step 3: Force Delete a Docker Image

If the image you are trying to delete is currently being used by one or more containers, Docker will not allow the image to be removed. In such cases, you can use the --force flag to force the deletion of the image:

docker rmi --force IMAGE_ID

For example:

docker rmi --force 2d696327ab2e

Step 4: Remove All Unused Docker Images

If you want to clean up your system by removing all unused or dangling Docker images (those without any associated tags), you can use the following command:

docker image prune

Docker will prompt you to confirm the deletion of all unused images. You can bypass the confirmation prompt by using the -f option:

docker image prune -f

This is particularly useful for managing disk space on a WindowsVPS, where optimizing resources on your VPS server ensures better performance.

Step 5: Delete All Docker Images

If you want to remove all Docker images from your system, you can combine the docker images -q command, which lists all image IDs, with the docker rmi command:

docker rmi $(docker images -q)

This command will delete all Docker images on your system. Use this with caution, as it will remove all images, including those that are still in use by containers.

Step 6: Verify Deletion

After deleting a Docker image, you can verify that it has been successfully removed by running the docker images command again:

docker images

If the image was deleted successfully, it will no longer appear in the list of images.

Step 7: Optimize Your VPS Server for Docker

When running Docker on a WindowsVPS, it’s important to manage your resources efficiently. Removing unused Docker images frees up disk space and helps your VPS server run more efficiently, especially when hosting multiple containers. A VPS provides dedicated resources that allow you to scale your Docker infrastructure, improving performance and reliability as your application stack grows.

Conclusion

By following this guide, you have learned how to delete Docker images on Linux. Regularly cleaning up unused Docker images helps optimize system performance, especially on a WindowsVPS, where VPS servers offer the flexibility and power to handle multiple Docker containers.

How to Delete a Docker Image on Linux

Docker allows you to create, manage, and remove containers and images easily. This guide will explain how to delete Docker images on a Linux system.

Step 1: List Docker Images

  • Before deleting a Docker image, it’s useful to list all available images. Run the following command to display all images on your system:
docker images

This command will display a table with the image repository, tags, image ID, creation date, and size.

Step 2: Remove a Specific Docker Image

  • To delete a Docker image, you need to know its IMAGE ID or REPOSITORY:TAG. Run the following command to remove a specific image by its ID:
docker rmi

You can also delete an image using its repository name and tag:

docker rmi :

Example: To delete an image named myapp with the tag latest, run:

docker rmi myapp:latest

Step 3: Force Delete a Docker Image

  • If the image is being used by any running or stopped containers, Docker will prevent you from deleting it. To force delete an image, use the --force or -f flag:
docker rmi -f

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

Step 4: Delete All Unused Docker Images

  • To delete all images that are no longer being used by containers (also known as “dangling” images), use the following command:
docker image prune

If you want to remove all unused images, even those that are not dangling, use the -a flag:

docker image prune -a

Step 5: Verify Image Removal

  • After removing images, you can verify that they have been deleted by listing the images again:
docker images

This will show the remaining images on your system, and the deleted images will no longer appear.

Conclusion

By following this guide, you now know how to delete Docker images on a Linux system, including removing specific images, force deleting, and cleaning up unused images.
