Uploading a new Docker image

1. Create an account on https://hub.docker.com/
2. Remember your account name and ask us to be made a "collaborator"
3. "Login" to your local Docker service using

   docker login

4. Make the wanted changes to our Dockerfile
5. Create a new Docker image

   docker build -t nuto_docker <nuto_source_directory>

6. Create a new tag (but give it a better name)

   docker tag nuto_docker nuto/nuto_docker:my_fance_new_tag

7. Push it to Docker Hub

   docker push nuto/nuto_docker:my_fancy_new_tag
