to use the `npm adduser` command. This

+Deploying Docker images to link:[Docker Hub] requires 
authentication information in the
+`~/.docker/config.json` file. This information can simply be added with the 
`docker login` command which will ask for

used to push images to Docker Hub which will
+be done automatically on `mvn deploy` or it can be triggered manually with 
`mvn dockerfile:push`.
