Challenge, Easy,  on  Kubernetes

Mount ConfigMap and Secret Using a Single Volume

Scenario

Create a Pod named app in the namespace exam using the image busybox.

Configure the container to execute the command:

sleep 3600

Ensure that the existing ConfigMap app-config and Secret app-secret are both available inside the container at the path /etc/app.

Define only one volume named app-config-vol and mount it as readOnly

No additional resources should be created.

Hint

A projected volume allows you to combine multiple sources (ConfigMaps, Secrets, etc.) into a single volume.

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 mount-configmap-and-secret-using-a-single-volume-df4de738

This will create a local copy of the challenge content in a directory named mount-configmap-and-secret-using-a-single-volume-df4de738. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge mount-configmap-and-secret-using-a-single-volume-df4de738

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
