Prove you can navigate Rancher's Cluster Explorer by creating a namespace called rancher-explorer in the local cluster - using the UI, not the command line. A quick, hands-on check that you found your way around the dashboard.
#Rancher#UI#Namespaces

You have toured the Rancher dashboard - now put it to use. This short challenge asks you to do one thing entirely through the Rancher UI: create a namespace called rancher-explorer in the local cluster.

Doing it in the UI (rather than with kubectl) is the point - it proves you can find your way to the right place in the Cluster Explorer and drive Rancher, which is what the rest of the course builds on.

Your Task

Open the Rancher UI (the Rancher tab), enter the local cluster, and create a namespace named exactly rancher-explorer.

Where do I create a namespace in the UI?

Enter the local cluster from the global navigation. In the Cluster Explorer, look under the Cluster section for Projects/Namespaces (Rancher groups namespaces there). Use the Create Namespace button, name it rancher-explorer, and create it.

It says my namespace was not created through Rancher

The check confirms the namespace is assigned to a Rancher Project - something Rancher does automatically when you create a namespace in its UI, but kubectl create namespace does not. If you created rancher-explorer with kubectl out of habit, delete it (kubectl delete namespace rancher-explorer) and create it again from the Rancher UI (it lands in Project: Default).

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 rancher-create-namespace-ui-a41237c6

This will create a local copy of the challenge content in a directory named rancher-create-namespace-ui-a41237c6. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge rancher-create-namespace-ui-a41237c6

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
