Copy following code and paste it in the Cloud Shell and press enter:
cat << EOF > startup.sh
#! /bin/bash
apt-get update

1 .Create an instance template :
gcloud compute instance-templates create nginx-template \ --metadata-from-file startup-script=startup.sh
2 .Create a target pool :
While you enter following command, it asks if you want to set it in southasia but press n, and then select us-east1 (20) number.
gcloud compute target-pools create nginx-pool
3 .Create a managed instance group :
gcloud compute instance-groups managed create nginx-group \ --base-instance-name nginx \ --size 2 \ --template nginx-template \ --target-pool nginx-pool
gcloud compute instances list
4 .Create a firewall rule to allow traffic (80/tcp) :
gcloud compute firewall-rules create www-firewall --allow tcp:80
gcloud compute forwarding-rules create nginx-lb \ --region us-east1 \ --ports=80 \ --target-pool nginx-pool
gcloud compute forwarding-rules list
5 .Create a health check :
gcloud compute http-health-checks create http-basic-check
gcloud compute instance-groups managed \ set-named-ports nginx-group \ --named-ports http:80
6 .Create a backend service and attach the manged instance group :
gcloud compute backend-services create nginx-backend \ --protocol HTTP --http-health-checks http-basic-check --global
gcloud compute backend-services add-backend nginx-backend \ --instance-group nginx-group \ --instance-group-zone us-east1-b \ --global
7 .Create a URL map and target HTTP proxy to route requests to your URL map :
gcloud compute url-maps create web-map \ --default-service nginx-backend
gcloud compute target-http-proxies create http-lb-proxy \ --url-map web-map
8 .Create a forwarding rule :
gcloud compute forwarding-rules create http-content-rule \ --global \ --target-http-proxy http-lb-proxy \ --ports 80
gcloud compute forwarding-rules list
