Docker Remove Unused

Docker is a popular containerization platform that allows developers to easily create, deploy, and run applications in containers. One of the benefits of using Docker is the ability to manage resources efficiently, including cleaning up unused containers, images, and volumes. This is where the docker system prune command comes in handy.

What is docker system prune?

The docker system prune command allows you to remove all unused resources used by Docker, such as containers, images, volumes, and networks. This command frees up disk space and improves performance by removing unused resources.

How to use docker system prune?

Using the docker system prune command is straightforward. Simply open your terminal and type:

docker system prune

This command will prompt you to confirm if you want to remove all unused resources. Type y to confirm, and Docker will start removing all unused resources.

If you want to skip the confirmation prompt, you can use the -f option:

docker system prune -f

This will force Docker to remove all unused resources without prompting for confirmation.

What resources are removed by docker system prune?

When you run the docker system prune command, it removes all unused resources. This includes:

• All stopped containers
• All networks not used by at least one container
• All dangling images (i.e., images that are not referenced by any tag)
• All unused volumes

Conclusion

In conclusion, docker system prune is an essential command that helps you clean up unused resources and free up disk space. By regularly running this command, you can keep your Docker environment clean and improve performance.
