Scenario cka-net-007 · about 6 minutes · 5 points · 6 grader checks

Expose a Deployment on a Service port that differs from the container port.

  • service
  • clusterip
  • targetport
  • networking

What you will practise

  • Distinguish Service port from targetPort
  • Create a ClusterIP Service with port mapping
  • Verify endpoints

Start this lab

With the CLI installed and signed in, this command provisions a two nodes cluster on your Mac, applies the scenario setup and prints the task below.

goldenkube start cka-net-007

Task

The task text exactly as the CLI shows it. Solve it on the cluster, then run goldenkube submit.

In namespace "net" a Deployment "front" (label app=front, nginx:1.27, pods listen on port 80) is running. Create a Service named "front-svc" in namespace "net" (type ClusterIP) that listens on port 8080 and forwards to the pods' port 80. It must select the "front" pods and have endpoints.
