I have an image named cptool:latest with the size of 0 bytes.

This is the line that is printed when using docker images -a

enter image description here

What is it and what is it needed for?

  • It's not a standard thing. If you don't know what originally created it then it's probably safe to `docker rmi cptool` to delete it. – David Maze Aug 25 '22 at 12:55
  • The docker cp utility copies the contents of SRC_PATH to the DEST_PATH . You can copy from the container's file system to the local machine or the reverse, from the local filesystem to the container. – Abhijith Chitrapu Aug 28 '22 at 05:52

You can check its history:

docker history --no-trunc 67b18221c757

Or use dive to explore this image.

But if those commands reports nothing, because of its size (0), then removing the image from your local registry is, as commented, the sensible option.
