-Create the Dockerfile in the root of the project.
-
-Then build the image from root.
-
-```
-docker build -t image-name .
-```
-
-The image name is defined at this point, not pre-defined.
-
-If successful, run the image:

-```
-docker run --name your-container-name image-name

-Again, the container-name is defined at the point of the `run` declaration.
