We've discussed this fact earlier that you can override the command specified by the command directive in your Dockerfile when you run the command to start your container from an image, and that's exactly what I've done here. Now I use the docker run command to bring up a second container from the same my-python-app image. Let's see what the differences are here in this second container. The first is the name of the container. It's my-second-python-app container. The second difference is that I mapped Port 5000 of the Docker container to Port 7000 on my local machine. This means that this app running within the second container will not clash with the first app that I already have running within my first container that's running on Port 5000. This app will run on Port 7000 of my local machine. The third difference here is, notice the last input argument, second_app.py.
