Challenge, Easy,  on  Kubernetes

Scale Deployment and Expose via NodePort Service

Scenario

An existing ecommerce-frontend-deployment Deployment is running in the ecommerce-platform namespace with 2 replicas.

The application runs on port 80 inside the containers and serves content from the ecommerce-frontend-config ConfigMap.

Your task is to:

  1. Scale the ecommerce-frontend-deployment to 5 replicas to handle increased traffic
  2. Add the label role: webfrontend to the pod template metadata
  3. Create a NodePort Service named ecommerce-frontend-service that:
    • Exposes the application on TCP port 8000
    • Uses the deployment's existing selector labels
# Test the service (replace <NodePort> with actual port)
curl http://cplane-01:<NodePort>

How to Author Challenges on iximiuz Labs

Instead of providing a subpar online editing experience, iximiuz Labs offers a helper CLI tool called labctl, allowing you to use your favorite text editor (or a full-featured IDE) to write content from the comfort of your local machine.

Install labctl CLI

curl -sf https://labs.iximiuz.com/cli/install.sh | sh

This will download and install the latest version of the labctl CLI. You only need to do this once per workstation.

Authorize labctl

labctl auth login

This will open a browser window asking you to authorize labctl to access your account. You need to do it after a fresh install of labctl and repeat it whenever the auth session expires.

Pull challenge content

labctl content pull challenge scale-deployment-and-expose-via-nodeport-service-03b090a5

This will create a local copy of the challenge content in a directory named scale-deployment-and-expose-via-nodeport-service-03b090a5. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge scale-deployment-and-expose-via-nodeport-service-03b090a5

Run this command in a separate terminal to continuously upload your changes to the server while editing the challenge in your favorite text editor or IDE.

You can also use labctl to create, list, and delete your content. Learn more about the available commands: labctl content --help
