I'll use the -it flag to tell Docker to take all of the output from the container and pipe it to this console window. I'll also use the -p flag to map port 5000 from inside of the container, which was exposed with the expose command in the Docker file, to port 5000 on this machine, on my local machine. And finally I'll specify the name of the image that I want to spin up. When I hit enter, Docker will take this image, create a container from it, and then run the container and show me the output. And it works really fast, so in just that amount of time I have the container spun up, Kestrel started up, and it's listening for requests.
