TL;DR

Add support for gcrane https://github.com/google/go-containerregistry/tree/main/cmd/gcrane

Detailed design

No response

Additional information

When doing multi-project deployment it would be useful to have the possibility to copy (docker) images between projects. This can be done via gcrane

Hi @iuadastra

Thanks for opening an issue. gcrane is independent from gcloud, so I don't think it makes a ton of sense to have it as part of the setup-gcloud command. We could investigate creating a new command, or just leveraging a composite command that uses go and installs gcrane at a specific version.

Hi @iuadastra

It would be best to raise this request with the gcrane team to see if they are interested in building or maintaining this.
