If you have the Dockerfile ready as shown in the last tutorial, you continue to build a new Docker image and run it.

1. Build the new image.

$ docker image build --tag python-web .

2. Create a container and run it.

$ docker container run --publish 8080:80 python-web
 * Serving Flask app "hello-web" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://0.0.0.0:80/ (Press CTRL+C to quit)
10.0.2.4 - - "GET / HTTP/1.1" 200 -
...
^C

3. Stop the container with CTRL+C and run it again in background.

$ docker container run --publish 8080:80 --detach python-web

$ docker container list --latest      
CONTAINER ID  IMAGE       COMMAND                CREATED        STATUS        PORTS               
7da8f1fa7fcc  python-web  "python hello-web.py"  6 seconds ago  Up 3 seconds  0.0.0.0:8080->80/tcp

As you can see, our new Python Hello Website is started now as a Docker container.
