Regex based routing setup for ingress in AKS - azure

Question

I am have a K8s cluster in Azure, in which I am wanting to host multiple web applications on with a single host. Each application has it's own service and deployment. How can I achieve something like the following routes?
MyApp.com
Partner1.MyApp.com
Partner2.MyApp.com
Here is what my yml file looks like currently:
apiVersion: apps/v1
kind: Deployment
metadata:
name: myapp
spec:
selector:
matchLabels:
app: myapp
template:
metadata:
labels:
app: myapp # the label for the pods and the deployments
spec:
containers:
- name: myapp
image: myimagename
imagePullPolicy: Always
ports:
- containerPort: 6666 # the application listens to this port
---
apiVersion: v1
kind: Service

spec:

app: myapp

What can I do to get the above routing?

Answer 1

Please run your two applications using kubectl
kubectl apply -f Partner1-MyApp.yaml --namespace ingress-basic
kubectl apply -f Partner2-MyApp.yaml --namespace ingress-basic
To setup for routing in your YAML file, If both application are running in Kubernetes cluster to route traffic in each application EXTERNAL_IP/static is needed to route the service, create a file name add this YAML code in below
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: partner-ingress-static
annotations:
nginx.ingress.kubernetes.io/ssl-redirect: "false"
nginx.ingress.kubernetes.io/rewrite-target: /static/$2
spec:
ingressClassName: nginx
rules:
- http:
paths:
- path: /static(/|$)(.*)
pathType: Prefix
backend:
service:
name: partner1-myapp
port:
number: 6669
