Challenge
Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
Challenge
Deploy an Application with kubectl
Before jumping into packaging and deploying kubernetes (k8s) applications with helm, you will deploy an application with kubectl. This will give you some insights on why helm is so useful for managing k8s apps.
Challenge
Create Your First Helm Chart
In this challenge, you will create your first helm chart to deploy a mysql database.
Challenge
Install a CMS with Helm
You'll review, install, and validate an existing helm chart for WordPress, which is a Content Management System (CMS).
Challenge
Use a Repository to Store Your Charts
You have a local helm repository already running in your lab environment! In this challenge, you'll learn to store and pull helm charts to/from this private helm repository.
Challenge
Manage Dependencies Between Charts
At this point, you have two charts that depend on each other. Now you'll use helm to define and manage dependencies between both charts.
