Create and Manage Cloud Resources: Challenge Lab Solution

Lab Link : Here

Task 1 :

• Create a project jumphost instance
• You will use this instance to perform maintenance for the project.

Requirements:

• Name the instance nucleus-jumphost-581 .
• Use an f1-micro machine type.
• Use the default image type (Debian Linux).

gcloud compute instances create nucleus-jumphost-581 \
          --network nucleus-vpc \
          --zone us-east1-b  \
          --machine-type f1-micro  \
          --image-family debian-9  \
          --image-project debian-cloud \
          --scopes cloud-platform \
          --no-address

---

Task 2 :

• 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 placeholder; the team will replace the container with their own work later.
• Expose the app on port 8082 .

gcloud container clusters create nucleus-backend \
          --num-nodes 1 \
          --network nucleus-vpc \
          --zone us-east1-b

gcloud container clusters get-credentials nucleus-backend --zone us-east1-b

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

kubectl expose deployment hello-server \
          --type=LoadBalancer \
          --port 8082

---

Task 3 :

• 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.

Create an instance template. Create a target pool. Create a managed instance group. Create a firewall rule named as permit-tcp-rule-895 to allow traffic (80/tcp). Create a health check. Create a backend service, and attach the managed instance group with named port (http:80). Create a URL map, and target the HTTP proxy to route requests to your URL map. Create a forwarding rule.
