Answer 1

If you running windows 7 docker Registry

1. Start **Docker Quick Start terminal** run (this terminal enables connection ) Until you pushed images , that will keep token alive .
2. Login docker login

3. Make sure you tag the image with username

   docker build -f Dockerfile -t 'username'/imagename

4. push image

   docker image push username/imagename

Note: image name all lowercase
