Challenge, Medium,  on  Kubernetes

Debug Why a ConfigMap Could Not Be Created

Scenario

A Pod named nara in the japan namespace is not running. The Pod manifest is at /home/laborant/nara.yaml. The developer tried to create a required ConfigMap but was not able to create it.

Task

Inspect the manifest at /home/laborant/nara.yaml, identify the ConfigMap the Pod needs, and find out why it could not be created.

Fix the issue and create the ConfigMap with the following key-value pair.

KeyValue
DEERDeer

Ensure the Pod nara starts running successfully after the fix.

Do not modify the Pod manifest at /home/laborant/nara.yaml.

Hint 1

Inspect any ResourceQuota restrictions in the japan namespace that could be blocking object creation. Use kubectl describe resourcequota -n japan to review the current limits and usage.

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 debug-why-a-configmap-could-not-be-created-1589e713

This will create a local copy of the challenge content in a directory named debug-why-a-configmap-could-not-be-created-1589e713. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge debug-why-a-configmap-could-not-be-created-1589e713

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
