About This Course

This course takes you from zero to production-ready Rancher management. You will install Rancher on a K3s cluster, learn to manage workloads and cluster resources through the Rancher UI, and progress to multi-cluster operations, GitOps-driven continuous delivery, observability, and day-2 operations.

What You Will Learn

The course is organized into four modules that build on each other:

  • Module 1 - Rancher Fundamentals: what Rancher is, installing it on K3s, and navigating the UI.
  • Module 2 - Working with Rancher: deploying workloads, managing cluster resources, and installing platform apps from the catalog with Kong Gateway and Kong plugins.
  • Module 3 - Multi-Cluster and GitOps: importing and managing multiple clusters, GitOps delivery with Rancher Fleet, and running the CI/CD loop against a Git server you own.
  • Module 4 - Operations: observability with Prometheus and Grafana, logging with Loki and Grafana Alloy, security and access control, and day-2 operations like backup and upgrades.

Prerequisites

  • Basic familiarity with Kubernetes concepts (pods, deployments, services, namespaces)
  • Comfort with the Linux command line
  • Understanding of Helm chart installation basics

How to Author Courses 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 course content

labctl content pull course Managing-Kubernetes-with-Rancher-479e4d7b

This will create a local copy of the course content in a directory named Managing-Kubernetes-with-Rancher-479e4d7b. You only need to do this once per course.

Stream your changes

labctl content push -fw course Managing-Kubernetes-with-Rancher-479e4d7b

Run this command in a separate terminal to continuously upload your changes to the server while editing the course 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
