Challenge, Medium,  on  Kubernetes

Bootstrapping Pod Networking with Calico

Scenario

You are working with a Kubernetes cluster initialized without a Container Network Interface (CNI).

Pod networking is not configured, and the cluster requires a networking solution that uses the cluster Pod CIDR with a /16 mask.

Install Project Calico to enable pod networking and ensure the Calico installation reports a healthy status.

The official Tigera Operator manifest is available at:

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 bootstrapping-kubernetes-networking-with-calico-09cb609a

This will create a local copy of the challenge content in a directory named bootstrapping-kubernetes-networking-with-calico-09cb609a. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge bootstrapping-kubernetes-networking-with-calico-09cb609a

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
