Loadbalancer challenge lab

 

Your challenge

As soon as you sit down at your desk and open your new laptop, you receive several requests from the Nucleus team. Read through each description, and then create the resources.

Task 1: Create a project jumphost instance

You will use this instance to perform maintenance for the project.

Requirements:

• Name the instance nucleus-jumphost-598 .
• Use an f1-micro machine type.
• Use the default image type (Debian Linux).

gcloud compute instances create nucleus-jumphost-598 --machine-type=f1-micro

ask 2: Create a Kubernetes service cluster

There is a limit to the resources you are allowed to create in your project. If you don't get the result you expected, delete the cluster before you create another cluster. If you don't, the lab might end and you might be blocked. In order to get your account unblocked, you will have to reach out to Qwiklabs Support.

The team is building an application that will use a service running on Kubernetes. You need to:

• Create a cluster (in the us-east1-b zone) 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 .

Task 3: Set up an HTTP load balancer

You will serve the site via nginx web servers, but you want to ensure that the environment is fault-tolerant. Create an HTTP load balancer with a managed instance group of 2 nginx web servers. Use the following code to configure the web servers; the team will replace this with their own configuration later.

There is a limit to the resources you are allowed to create in your project, so do not create more than 2 instances in your managed instance group. If you do, the lab might end and you might be banned.

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

Copied!

You need to:

• Create an instance template.
• Create a target pool.
• Create a managed instance group.
• Create a firewall rule named as allow-tcp-rule-554 to allow traffic (80/tcp).
• Create a health check.
• Create a backend service, and attach the managed instance group.
• Create a URL map, and target the HTTP proxy to route requests to your URL map.
• Create a forwarding rule.
