How to Add static public IP adress to a kubernetes/nginx ingress controller in an AKS cluster without helm

I have an Azure Kubernetes Service cluster and created a public IP address via:

az network public-ip create --resource-group MC_myResourceGroup_myAKSCluster_eastus --name myAKSPublicIP --sku Standard --allocation-method static --query publicIp.ipAddress -o tsv

I created the ingress controller via:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.8.1/deploy/static/provider/cloud/deploy.yaml

To try and add the IP address to the ingress-controller, I tried following this tutorial, but since I have not installed the ingress controller via helm it does not seem to be working.

An important note is that, without the Azure IP address, the ingress controller does work, but I want to create a static IP so that it does not get delete when the ingress controller gets deleted.

Update:

I followed @silent's advice by:

  1. Going to: https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.8.1/deploy/static/provider/cloud/deploy.yaml
  2. Copying the yaml code and pasting it in a file
  3. Adding the lines @silent provided in the following piece from the yaml:
kind: Service
metadata:
  annotations:
    service.beta.kubernetes.io/azure-load-balancer-health-probe-request-path: /healthz
    service.beta.kubernetes.io/azure-load-balancer-ipv4: <Azure-IP>
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
    app.kubernetes.io/version: 1.8.1
  name: ingress-nginx-controller
  namespace: ingress-nginx
spec:
  externalTrafficPolicy: Local
  ipFamilies:
  - IPv4
  ipFamilyPolicy: SingleStack
  ports:
  - appProtocol: http
    name: http
    port: 80
    protocol: TCP
    targetPort: http
  - appProtocol: https
    name: https
    port: 443
    protocol: TCP
    targetPort: https
  selector:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/name: ingress-nginx
  type: LoadBalancer

When I apply the file without the annotations @silent provided, it works, but of course with a random IP address. When I add the annotations, the service's EXTERNAL-IP will remain <PENDING>.

You just need to adjust your yaml file and set the IP address of the service (through annotations, as this is the currently recommended way):

Should be this one

apiVersion: v1
kind: Service
metadata:
  annotations:
    service.beta.kubernetes.io/azure-load-balancer-health-probe-request-path: /healthz
    service.beta.kubernetes.io/azure-load-balancer-ipv4: 1.2.3.4 # <-- here put your ip
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
    app.kubernetes.io/version: 1.8.1
  name: ingress-nginx-controller
  namespace: ingress-nginx
spec:
  externalTrafficPolicy: Local
  ipFamilies:
  - IPv4
  ipFamilyPolicy: SingleStack
  ports:
  - appProtocol: http
    name: http
    port: 80
    protocol: TCP
    targetPort: http
  - appProtocol: https
    name: https
    port: 443
    protocol: TCP
    targetPort: https
  selector:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/name: ingress-nginx
  type: LoadBalancer
