My solution based on this repository as well as my notes and the general course.
First Task
gcloud config set project PROJECT_ID_CAN_BE_FOUND_ON_YOUR_LAB
gcloud config set compute/region REGION
gcloud config set compute/zone ZONE
gcloud compute instances create nucleus-webserver1 --machine-type=e2-micro
Seccond task - copy and past the following lines into your cloud console to create the startup.sh file which will be the base for your template startup script
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

OPTIONAL
- you can check your instances from the loadbalancer external ip address only http will work, because of the certification need for https
http://[EXTERNAL_IP]:80
JUST DON'T FORGET CHANGE THE PARAMETERS LIKE PROJECT, REGION, ZONE, INSTANCE NAME

Hi, I'm wondering why do you all create a target pool ? I thought that only used on network/global loadbalancing and not on http loadbalancing but now I'm kind of confused..
the solutions doesn't work!
Please verify the web servers are serving on frontend of HTTP(s) Load Balancer.
Please create the managed instance group with 2 nginx web-server.

REGIONS AND ZONES MUST VARY IN YOUR CASE.
2 STEP.
-

-
gcloud compute firewall-rules create www-firewall --allow tcp:80
change the rule as necessary in your case
5. gcloud compute firewall-rules create permit-tcp-rule-649 --network=default --action=allow --direction=ingress --source-ranges=130.211.0
