Remove old and unused Docker images

Question

I want to remove images pulled months ago, which is having the correct TAG. So, I'm trying to find a way to remove general unused images, which includes both untagged and other images such as pulled months ago with correct TAG.

Answer 1

Here is what you can try.

docker system prune will delete all dangling data (i.e. In order: containers stopped, volumes without containers and images with no containers). Even unused data, with -a option.

You can also use one of the below option to fulfill your requirement:

• docker container prune
• docker image prune
• docker network prune
• docker volume prune

For unused image,

docker image prune -a

I hope that it will help you resolve your query.
