A simple docker project with python-flask.
You can build this image by
$ docker build -t example_project_name .
or you can get this image on docker hub
$ docker pull guodashun/docker_flask
You need to give a port which you like, for example, 5000
$ docker run -d -p 5000:1234 guodashun/docker_flask
Then you can go to http://127.0.0.1:5000/ in your favorite browser to check it out.
