 This will start a container running NGINX.  NGINX listens on port 80 by default, so we are telling Docker to expose the internal port 80 to our local port 8080.  Notice the -p for publishing ports follows the syntax of <External Port>:<Internal Port>.

 Your mission if you choose to accept it, is to run an nginx container that hosts your own created HTML file.
 You will accomplish this by using the docker run command as you did above to create an nginx container, but this time you will use a [volume mount](https://docs.docker.com/storage/volumes/) to mount a local **folder** that contains an HTML file into the running container.

 Now you will need to run the nginx container with the '-v' option and replace the "/some/content" with the path to the **folder** containing your newly created HTML.  NOTE: the example from hub.docker.com doesn't add the -p (publish port) option, so if you use it as is, you won't be able to access your nginx container... so add the "-p 8080:80" option to it along with the new volume option.  
 
-NOTE: When you run the command the first time with a volume option, Docker will prompt you to ask you if you want to share the folder with Docker.  So, watch for a pop-up to ask you to share the folder.  Also, if you are on Windows, you are best to run this command from the basic command prompt or powershell. Using something like git bash can confuse things since it typically expect linux style paths.
