Nginx ingress configuration for Kubernetes cluster hosted on windows - windows

Question

I am running Kubernetes cluster on my windows PC via Docker desktop. I am trying to create a very basic pod with a simple ingress configuration, but it doesn't seem to work. I thought the backend pod + service + ingress is a very basic setup, however I don't find a lot of help online. Please advise what I am doing wrong here.
My deployment.yaml file
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx
spec:
replicas: 3
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:latest
ports:
- containerPort: 80
service.yaml
apiVersion: v1
kind: Service
metadata:
name: test-cluster-ip
spec:
selector:
app: nginx
ports:
- protocol: TCP
port: 1234
targetPort: 80
ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: minimal-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
ingressClassName: nginx
rules:
- http:
paths:
- path: /testpath
pathType: Exact
backend:
service:
name: test-cluster-ip
port:
number: 1234
This is what I see when I access localhost from the browser
Also, I would like to ask if it is uncommon to run Kubernetes on windows even for testing (especially with ingress). I don't seem to find a lot of examples in the internet.

I thought the backend pod + service + ingress is a very basic setup, however I don't find a lot of help online. Please advise what I am doing wrong here.
It is indeed a very basic setup. And your k8s deployment/service/ingress yaml files are correct.
First, check if you installed NGINX ingress controller. If not, run:
$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.1/deploy/static/provider/cloud/deploy.yaml
After that, you will be able to reach the k8s cluster using the following URL:
http://kubernetes.docker.internal/
But deploying ingress like this:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: minimal-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
ingressClassName: nginx
rules:
- http:
paths:
- path: /testpath
pathType: Exact
backend:
service:
name: test-cluster-ip
port:
number: 1234
you are configuring the ingress to rewrite /testpath to the /. And requesting url without /testpath will return 404 status code.
See more rewrite examples here.
So, if you use the following URL, you will get the Nginx webpage from k8s deployment.
http://kubernetes.docker.internal/testpath
