Exercises

Exercise 1: Compute Engine VM

  1. Create a Compute Engine VM using gcloud compute instances create
  2. SSH into the VM: gcloud compute ssh my-vm --zone=us-central1-a
  3. Install nginx on the VM
  4. Open port 80 in the firewall: gcloud compute firewall-rules create allow-http --allow=tcp:80
  5. Visit the VM’s external IP in a browser
  6. Clean up: delete the VM and firewall rule

Exercise 2: GKE Autopilot Cluster

  1. Create a GKE Autopilot cluster in us-central1
  2. Configure kubectl to use the new cluster
  3. Deploy the Google sample app: kubectl create deployment hello-app --image=us-docker.pkg.dev/google-samples/containers/gke/hello-app:1.0
  4. Expose it with a LoadBalancer service
  5. Access the app via the external IP
  6. Scale the deployment to 3 replicas
  7. Clean up: delete the cluster

Exercise 3: Cloud Run Deployment

  1. Create a simple Dockerfile for a “Hello World” HTTP server
  2. Build and push it to Artifact Registry
  3. Deploy to Cloud Run with --allow-unauthenticated
  4. Test the URL that Cloud Run provides
  5. Update the service with a new image revision
  6. Split traffic 50/50 between two revisions

Exercise 4: Cloud Build CI/CD Pipeline

  1. Fork a sample application repository
  2. Create a cloudbuild.yaml that:
    • Builds a Docker image
    • Runs tests
    • Pushes to Artifact Registry
    • Deploys to Cloud Run
  3. Connect Cloud Build to your repository
  4. Trigger a build by pushing a commit
  5. Observe the build logs in Cloud Console

Exercise 5: Infrastructure with Terraform on GCP

  1. Create a Terraform configuration that provisions:
    • A VPC network with a subnet
    • A GCS bucket
    • A Compute Engine VM in the VPC
  2. Store Terraform state in a GCS backend
  3. Run tofu init, tofu plan, tofu apply
  4. Verify resources in GCP Console
  5. Run tofu destroy to clean up
