Task 1: Create a project jumphost instance

Navigation menu > Compute engine > VM Instance


Task 2: Create a Kubernetes service cluster

gcloud config set compute/zone us-east1-b

gcloud container clusters create nucleus-webserver1

gcloud container clusters get-credentials nucleus-webserver1

kubectl create deployment hello-app --image=gcr.io/google-samples/hello-app:2.0

kubectl expose deployment hello-app --type=LoadBalancer --port 8080

kubectl get service 


Task 3: Setup an HTTP load balancer

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

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

"Please verify the web servers are serving on frontend of HTTP(s) Load Balancer"

For this specific error if you have steps right, I think its in the Progress checker the issue is, beside creating the FW Rule with the dynamic name generated in Description, add identically rule:

gcloud compute firewall-rules create web-server-firewall --allow tcp:80 --network VPC_NAME

Fixed it immediatly for me, so its the name that is the issue

thank you so much 🙏🥂

I was getting the error "Please create the managed instance group with 2 nginx web server" after doing everything, and using the command gcloud compute instance-groups managed set-named-ports YOUR_MANAGED_INSTANCE_GROUP_NAME --named-ports http:80 --zone=YOUR_ZONE solved it for me and I could get the final check in the lab.
