Create and Manage Cloud Resources: Challenge Lab

This is a challenge lab and after completing it you earn a Skill Badge.

Task 1. Create a project jumphost instance

Solution

• Go To Navigation Menu -> Compute Engines -> VM Instance
• They click Create Instance
• Name the instance as it is mentioned in your task, dont copy mine.
• Make sure Zone is us-east1-b
• Change Machine Type to f1-micro

• Check if the default image is debian , if not change it to debian
• Then Press Create (Takes 2-3 min time to create).
• Then Check Progress it will be completed.

Task 2. Create a Kubernetes service cluster

Solution

• Create a cluster (in the us-east1-b zone) to host the service : -

gcloud config set compute/zone us-east1-b
gcloud container clusters create nucleus-jumphost-webserver
gcloud container clusters get-credentials nucleus-jumphost-webserver

• 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 : -

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

• Expose the app on port App port number : -

Please Note in my case port is mentioned as 8080 , it might be different for you, please change it if not same.

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

Task 3. Set up an HTTP load balancer

Solution

First open cloud shell and type this command to create a new startup.sh file

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

• Create an instance template : -

gcloud compute instance-templates create nginx-template \
--metadata-from-file startup-script=startup.sh

• Create a target pool : -

  gcloud compute target-pools create nginx-pool
  

You need to select n and choose us-east1 form the options in my case it was on option 26.

• 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

• Create a firewall rule named as Firewall rule to allow traffic (80/tcp) : -

Please dont forget to replace {YOUR-FIREWALL-NAME} with firewall rule name provided to you from the below code.

gcloud compute firewall-rules create {YOUR-FIREWALL-NAME} --allow tcp:80
gcloud compute forwarding-rules create nginx-lb \
--region us-east1 \
--ports=80 \
--target-pool nginx-pool
gcloud compute forwarding-rules list

• 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
  

• Create a backend service, and attach the managed instance group with named port (http:80) : -

  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
  

• Create a URL map, and target the 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
  

• 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
  

Now wait for 4-5 mins

And then click on Check my Progress

Congratulations
