Understand ResourceQuota limits and create a Pod with Guaranteed QoS class that uses half of the namespace's allocated resources.
#ckad#cka#resourcequota#qos

Scenario

In the prod namespace, a ResourceQuota has been created that defines resource limits for the namespace.

Check the ResourceQuota in the prod namespace to determine the CPU and memory limits that are set.

Then, create a Pod named redis-pod using the image redis:latest.

Set the CPU and memory limits of the Pod to half of the limits defined in the ResourceQuota, and ensure that the Pod is configured under the Guaranteed QoS class.

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 create-pod-with-guaranteed-qos-under-resourcequota-limits-e2b67ade

This will create a local copy of the challenge content in a directory named create-pod-with-guaranteed-qos-under-resourcequota-limits-e2b67ade. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge create-pod-with-guaranteed-qos-under-resourcequota-limits-e2b67ade

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
