Firstly, create a repository on Docker Hub.
In order to push a repository to the Docker Hub, you need to name your local image using your Docker Hub username and the repository name.
docker tag phx:latest phxtest/phxtest:latest
docker push phxtest/phxtest
docker pull phxtest/phxtest # test

One way is to type a non-breaking space (Ctrl+Shift+Spacebar) at the end of the line, select from the end of word to the end of the line, and then apply underline.
A better way is to set a tab with underline leader at the right margin, and then you can press Tab after the end of word to create an underline to the right margin. This method is better (and faster) than using underlined spaces because the underline will end evenly at the right margin, whereas underlined spaces tend to be slightly uneven at the right margin.
How do I underline the space AFTER a word in Microsoft Word?
