Copy docker image between repositories

Question

I have 2 private docker repositories. Is any way how can I copy one image from one repository to the second one?

Answer 1

Can be done with https://github.com/containers/skopeo

Example for the README:

skopeo copy docker://quay.io/buildah/stable docker://registry.internal.company.com/buildah

The advantage is that Skopeo does not require Docker on the machine it runs on.
