Task 1

gcloud compute instances create $INSTANCE_NAME \
    --zone=$ZONE \
    --tags=network-lb-tag \
    --machine-type=e2-micro \
    --image-family=debian-11 \
    --image-project=debian-cloud
Task 2

0. Create the startup script for the web servers:
cat << EOF > startup.sh
#! /bin/bash
apt-get update
apt-get install -y nginx
service nginx start
sed -i -- 's/nginx/Google Cloud Platform - '"\$HOSTNAME"'/' /var/www/html/index.nginx-debian.html
EOF
1. Create a static external IP address for your load balancer:
gcloud compute addresses create network-lb-ip-global \
  --ip-version=IPV4 \
  --global
2. Create an instance template:
gcloud compute instance-templates create nucleus-webserver-template \
    --machine-type=e2-medium \
    --metadata-from-file=startup-script=startup.sh \
    --image-family=debian-11 \
    --image-project=debian-cloud \
    --region=global \
    --tags=allow-health-check,network-lb-tag
3. Create a managed instance group based on the template:
gcloud compute instance-groups managed create nucleus-webserver-group \
    --template=nucleus-webserver-template \
    --size 2 \
    --zone $ZONE
4.Create a firewall rule to allow traffic on port 80:
gcloud compute firewall-rules create $FIREWALL_RULE \
    --target-tags network-lb-tag --allow tcp:80

gcloud compute firewall-rules create nucleus-fw-allow-health-check \
    --network=default \
    --action=allow \
    --direction=ingress \
    --source-ranges=130.211.0.0/22,35.191.0.0/16 \
    --target-tags=allow-health-check \
    --rules=tcp:80
5. Create a health check:
gcloud compute health-checks create http nucleus-health-check \
    --port 80
6. Create a backend service and add the instance group:
gcloud compute backend-services create nucleus-backend-service \
    --protocol=HTTP \
    --port-name=http \
    --health-checks=nucleus-health-check \
    --global

gcloud compute backend-services add-backend nucleus-backend-service \
    --instance-group=nucleus-webserver-group \
    --instance-group-zone=$ZONE \
    --global
7. Create a URL map to route the incoming requests to the default backend service:
gcloud compute url-maps create nucleus-url-map \
    --default-service=nucleus-backend-service
8. Create a target HTTP proxy to route requests to your URL map:
gcloud compute target-http-proxies create nucleus-http-proxy \
    --url-map=nucleus-url-map
9. Create a global forwarding rule:
gcloud compute forwarding-rules create nucleus-http-forwarding-rule \
    --address=network-lb-ip-global \
    --global \
    --target-http-proxy=nucleus-http-proxy \
    --ports=80
