question: add multiple tags to target image

[rgrzesk]

I am currently copying images by adding a new tag:
gcrane cp europe-west3-docker.pkg.dev/project-a/a-registry/main:latest europe-west3-docker.pkg.dev/project-b/b-registry/main:newTag

Is it possible to add multiple tags to the target? So that in project-b my main has eg. tags: newTag, newTag1, newTag2?

This issue is stale because it has been open for 90 days with no
activity. It will automatically close after 30 more days of
inactivity. Keep fresh with the 'lifecycle/frozen' label.

This actually would be a handy feature

@imjasonh can we re-open this one?

I have a use case where someone is wanting to copy an image with all of the same tags it has in the origin registry. We can get a list of all tags pointing to the digest through other means but would like to avoid a looping shell script to recreate them if possible.

Would we want to have this be atomic, rolling back any applied tags if any of them fail to be added, or simply warn that not all of them were applied?
