Helm is a tool used to package Kubernetes manifest files that are used to install a cloud-native application. Deployments, Services, Ingresses, ConfigMaps, etc. are all packed into a Helm chart. Using this Helm chart, you can deploy the app to a Kubernetes cluster the same way you use apt-get in Ubuntu, or brew on a macOS.After completing this course, you will have a working knowledge of Helm. You’ll be able not only to use ready-made Helm Charts to automate day-to-day deployments, but you’ll also automate the most complex Kubernetes deployments and contribute them to the community.I’ve designed this course to focus on the important parts of Helm. I did my best not to bother you with boring material that you’d seldom use in your day-to-day life as a Helm and Kubernetes engineer.
Instead, I will give you the core stuff of the tool together with some tips and tricks that will let you code Helm charts like a pro in no time!To get the most out of this course, I highly encourage you to open your laptop and do the labs that I explain in the class. There’s nothing better than getting your hands dirty learning a new tool or technology. That way, by the end of this course, you’ll find yourself already developing, applying, maintaining, and even sharing your very own Helm charts.The best way to learn any tool is by using it! In this course, we’ll work together to deploy ready-made Helm charts to Kubernetes using Helm. After mastering that, we’ll start analyzing the Helm chart bit by bit. Along the way, you’ll learn the following:Understand why we need a package manager for Kubernetes Deploying Helm to minikube (local Kubernetes cluster)Understanding Helm repositoriesAdding one or more Helm repositories to your systemSearching the Helm repository for your desired ChartUsing Helm to deploy ready-made Charts from popular repositoriesInspecting a Helm Chart deploymentUpgrading a Helm deployment and viewing its historyCustomizing the Helm
Chart to your own needs by modifying the values fileHow (and when) to create your own Helm ChartsUnderstanding Helm TemplatesTesting your Helm templates without applying them using the dry-run flag.Revisiting Helm history by upgrading and rolling back package deploymentsUsing Helm functions (include, indent, nindent, toYaml, b64enc, and more)Decision making using conditional and logical statements (IF, NOT, AND, OR)Loop through simple and complex objects using the “range” keywordDeep diving into Helm variablesDebugging your Helm chartsCreating your own Helm repositories and pushing ChartsDeploying even more complex Kubernetes environments using Helm Chart dependenciesLearning about popular community-based Helm projects like ChartmuseumExtending Helm by building your own repositoriesExploring different Helm plugins to automate repetitive tasks and store charts in the cloudBuild your own Helm plugins and use custom commands and protocolsConfigure Helm to create your own specific boilerplate charts using Helm startersWith a 30-day money-back guarantee, no questions asked, you have zero risk trying out this course.
