Configure Static IP Nginx ingress Kubernetes - Linux Guru

You have a web server running on kubernetes and expose it on a domain name and you need the external ip of an application to be a static ip that does not change.

• Reserve a new static IP address for INGRESS.
• Reserve a static external IP address named my-website-ip by run following command from your machine.

$ gcloud compute addresses create my-website-ip --global

here now we have reserved the static ip for the ingress, lets create ingress controller for the application and attached the static ip.

• lets create ingress file and describe the service name and static IP.

$ ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: yourappname-ingress
  annotations:
    kubernetes.io/ingress.global-static-ip-name: "my-website-ip"
spec:
  backend:
    serviceName: mywebsite-service
    servicePort: 80

Apply the ingress file and check your app, It should be access by static IP and you should point that IP to your domain name.
