Create an nginx load balancer without using gcp load balancer

Question

I've been using GCP load balancer but its getting expensive now, my expenditure has increased majorly. I thought of using it without cloud, how do i do this?

Yes this is possible. Deploy your ingress controller, and deploy it with a NodePort service. Example:

---
apiVersion: v1
kind: Service
metadata:
  name: nginx-ingress-controller
  namespace: kube-system
  labels:
    k8s-app: nginx-ingress-controller
spec:
  type: NodePort
  ports:
  - port: 80
    targetPort: 80
    nodePort: 32080
    protocol: TCP
    name: http
  - port: 443
    targetPort: 443
    nodePort: 32443
    protocol: TCP
    name: https
  selector:
    k8s-app: nginx-ingress-controller

Now, create an ingress with a DNS entry:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: my-ingress
spec:
  rules:
  - host: myapp.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: my-app-service 
          servicePort: 80
