[gouyang]

Push the same image to docker-daemon several times, it's just one image ID shows in docker images

[rhatdan]

@nalind Is this something your storage work is going to fix?

[nalind]

Yes, this is something that should be fixed by containers/image#305.

[nalind]

Just to be clear, what's the command you're using to push the image?

[gouyang]

the command should be buildah push docker.io/library/nginx:latest containers-storage:docker.io/library/nginx:latest

[boaz0]

ping @nalind - can I close this ticket as containers/image#305 fixes it?

[gouyang]

Tested it, the problem goes alway
