1 .Create an instance template :
gcloud compute instance-templates create nginx-template \
--metadata-from-file startup-script=startup.sh
2 .Create a target pool :
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
