Hello,

I want to preserve the Repository Name and Tag when I save a docker Image that I am building with Packer.

Thanks

This is possible with the post-processors. Set the `repository` flag on the [`docker-tag`](https://www.packer.io/plugins/post-processors/docker/docker-tag) post-processor and the `login_server` option in the `docker-push` postprocessor if you need to push it to a specific registry.

Have you tried this? What errors are you getting, if any?
