docker run -d -p 5000:5000 --name flaskweb --link db:db anguda/python-flask-app:web

Are you intersted to build the docker images and explore source code, then follow the below steps.

Are you using kubernetes as a service, then here's commands to run your application as pods

kubectl create -f db-deployment.yaml

kubectl create -f app-deployment.yaml

To get nodeport of app deployment, run the below command

kubectl get svc
