The build is successful. You can see that with the -t flag,
you can set a name that can be used to call the image
more easily. The. at the end of the command tells
Docker to look for the Dockerfile in the local directory.
You could also use the -f flag with a path to the location
of Dockerfile file, if it is not in your current directory.
Docker also accepts a URL to the Dockerfile, such as at
GitHub. As shown in this example, the name Dockerfile
must be capitalized and one word.
When an image is built, you can use docker image ls to
see it in local storage:

$ docker image ls
