The prune subcommand used as docker image prune offers more functionalities than the traditional one tag one image deletion. Each version of an image is stored separately in Docker, but it’s organised in layers so that many new versions don’t take up twice as much space. The image id is equal to the sha256 hash function of the latest layer of the Image. For deleting Node Image, we used the first three characters, and deletion was initiated. To delete, just put the first few initial unique characters of the Image ID. You don’t need to plug all characters of the SHA256 (cryptographic hash function) of any Image. Running docker rmi Image_id removes the specific docker image from your host. Having the ID from the Image ID field helps you to delete a specific Image. This command is helpful in the context of deleting images when you’re targeting some specific image. Running docker image ls would list all of the images available on your host OS.

The details include images, containers changing the file system, build cache, and Volumes which you can walk through in the bottom Image. Running docker system dfwould list all the storage used by Docker in its isolated environment.

If you complain about the same storage issues, this blog post will free you from the “not enough storage” dilemma. The one problem most of the people I talk to is keeping track of storage (images, volumes) in the isolated environment and making sure your storage space is not over utilised. The ease and agility docker provide makes it the preferred engine to explore for any beginner or enterprise looking towards containers. Docker has revolutionised containers even if they weren’t the first to walk the path of containerisation.
