frontend-v1 | First version of Penguin Statistics front | Analytics library

Welcome to the community!

I reproduced your example and made it work fine. I forked your repository, made some changes to js files and package.json and added Dockerfiles (you can see this commit here

Since I didn't change database settings in settings.py I attached it as a configMap to backend deployment (see here how it's done). Config map was created by this command:

kubectl create cm django1 --from-file=settings.py

The trickiest part here is to use your domain name kubernetes.docker.internal and add your port with /backend path to environment variables you're passing to your frontend application (see here)

Once this is done, it's time to set up an ingress controller (this one uses apiVersion - extestions/v1beta1 as it's done in your example, however it'll be deprecated soon, so it's advised to use networking.k8s.io/v1 - example of a newer apiVersion is here):
