Example – Python/Flask container image

To walk through the details of how to use Kubernetes, I have created two sample applications that you can download, or replicate to follow along and try out these commands. The first of these is a very simple Python application using the Flask library. The sample application is directly from the Flask documentation (http://flask.pocoo.org/docs/0.12/).

You can download a copy of this code from GitHub at https://github.com/kubernetes-for-developers/kfd-flask/tree/first_container. Since we will evolve these files, the code referenced here is available at the first_container tag. If you want to use Git to get these files, you can run the following commands:

git clone https://github.com/kubernetes-for-developers/kfd-flask

Then, go into the repository and check out the tag:
