What's the difference between 'docker save' and 'docker image save'?

Question

From the documentation:

docker save

Description: Save one or more images to a tar archive (streamed to STDOUT by default)

Usage docker save [OPTIONS] IMAGE [IMAGE...]

docker image save

Description: Save one or more images to a tar archive (streamed to STDOUT by default)

Usage docker image save [OPTIONS] IMAGE [IMAGE...]

Do they have the same behaviour or are there subtle differences depending on which one is used?

Answer 1

Both are same. Some frequently used commands have shorter aliases under docker subcommand.
