WhatsMyIp

Python Flask app to discover your own external IP!

This project is a helm chart which includes 2 pods:

1. The App pod: Python Flask- returns your external and internal IP addresses.
2. The Nginx pod: a reverse proxy for the app.

Thats the app's output:

How does it work?

1. I created a Python Flask app. The deployment file pulls the app's docker image from Docker hub. (I also left the code public for your review)
2. The deployment of Nginx works as a reverse proxy for the app.
3. In the config file, I configured Nginx to route traffic to the app's ClusterIP service.
4. The NodePort service is then the deployment's gateway and is routing traffic to the Nginx pod.

So how can YOU use this app?

1. Install minikube (a single node kubernetes tool). It's a great way for you to learn k8s and practice the skills in your home environment. Your'e going to need a docker engine installed as well. OR You can deploy this chart on your cloud kubernetes distribution. (Eks, Ecs etc.)

2. Clone the repository.

3. Start the minikube cluster:

minikube start --driver=docker

3. Deploy the helm chart:

helm install ipapp ./ipappChart --values ./ipappChart/values.yaml

4. Expose the NodePort service (skip this step if you are running the app on a k8s cloud dist.)

minikube service nginx-service

The browser will automatically open the page and now you have your external IP address AND your app's pod IP address!
