Getting Started: Create and Manage Cloud Resources: Challenge Lab

Task 1: Create a project jumphost instance

Make sure you:

name the instance -- nucleus-jumphost

use the machine type -- f1-micro

use the default image type (Debian Linux)

Navigation menu > Compute engine > VM Instance

Name for the VM instance : nucleus-jumphost

Region : leave Default Region

Zone : leave Default Zone

Machine Type : f1-micro (Series - N1)

Boot Disk : use the default image type (Debian Linux)

Create.

Click Check my progress to verify the objective.

Task 2: Create a Kubernetes service cluster

The team is building an application that will use a service. This service will run on Kubernetes. 
You need to:
Create a cluster (in the us-east1 region) to host the service

Use the Docker container hello-app (`gcr.io/google-samples/hello-app:2.0`) as a place holder, the team will replace the container with their own work later

Expose the app on port 8080

Activate Cloud Shell ---- 

Paste this cmd step by step

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

We will serve the site via nginx web servers, but we want to ensure we have a fault tolerant environment, 
so please create an HTTP load balancer with a managed instance group of two nginx web servers. 
Use the following to configure the web servers, the team will replace this with their own configuration later.

You need to:

Create an instance template
Create a target pool
Create a managed instance group
Create a firewall rule to allow traffic (80/tcp)
Create a health check
Create a backend service and attach the manged instance group
Create a URL map and target HTTP proxy to route requests to your URL map
Create a forwarding rule

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 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

Can You please explain why we need target pool here?Is it because they have asked or is there any specific reason?

1. the first step is to create load balancer
   gcloud compute instance-templates create lb-backend-template \ --region=us-east1 \ --network=default \ --subnet=default \ --tags=allow-health-check \ --image-family=debian-9 \ --image-project=debian-cloud \ --metadata=startup-script='#! /bin/bash apt-get update apt-get install apache2 -y a2ensite default-ssl a2enmod ssl vm_hostname="$(curl -H "Metadata-Flavor:Google" \ http://169.254.169.254/computeMetadata/v1/instance/name)" echo "Page served from: $vm_hostname" | \ tee /var/www/html/index.html systemctl restart apache2'

I did the exact what is written in this git repo
but I am getting this message
anyone knows why ?

yup , I know what was the problem
it was with the name
grant-tcp-rule-985
