[Documentation]: K8s tutorial cannot start with Minikube (error with port 3000)

[orousseau49170]

Bug Description

When using Minikube to run the K8s tutorial with the current documentation (config.yaml), the curl command fails:

curl http://localhost:3000/upload
curl: (7) Failed to connect to localhost port 3000 after 0 ms: Couldn't connect to server

Expected Behavior

After a debug session with @noMoreCLI , we found that Minikube does not expose the LoadBalancer type by default

kubectl get services:
frontend-ext LoadBalancer 10.99.89.91 3000:30169/TCP 15h

As described in the documentation, you have to start a tunnel to expose it:
https://minikube.sigs.k8s.io/docs/handbook/accessing/

Just start a tunnel in another terminal:
minikube tunnel

I suggest to add a comment in the Readme documentation:

If you use Minikube, don't forget to start a tunnel to expose the LoadBalancer service

Affected Version

v1.0.0

Steps to Reproduce

use the kubernetes quick start scenario with Minikube

thanks @orousseau49170! Maybe we create a TROUBLESHOOTING.md file and store information like this one in it and point to it from the different docs, what do you think?
