Tagging and Pushing Images to DockerHub
You have just completed building a Dockerfile, and you are ready to push it to Docker Hub. First make sure that you have a Docker Hub account. Then build your image with the `VERSION` build argument that is set to `1.5`. Finally, tag the image to `latest`, and push both images to Docker Hub.
