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

Resolvi desta forma:

gcloud compute firewall-rules create grant-tcp-rule-408
--network=default
--action=allow
--direction=ingress
--source-ranges=130.211.0.0/22,35.191.0.0/16
--rules=tcp:80

This command resolve the problem, many thanks

If you are not doing it right in command line, you can see this video that shows how to run this Lab without command line. https://www.youtube.com/watch?v=zv25HHm8kmA

@cespirandelli some actions seem to be under the hood there, I am talking about target-pool, url map and a forwarding rule. right?

Thanks bro! 🥇

I was able complete 3rd task with

"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.

That did it! Thank you so much.

gcloud compute instance-groups managed set-named-ports YOUR_MANAGED_INSTANCE_GROUP_NAME --named-ports http:80 --zone=YOUR_ZONE

Thank you so much for this. This worked for me. Thanks a bunch!
