Regex based routing setup for ingress in AKS

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

        app: myapp # the label for the pods and the deployments
    spec:

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
