Are you already working with Kubernetes but tired of writing all these YAML files? Especially when you need to deploy lots and lots of applications?

If so, this course is just for you. You’ll learn about Helm, a popular, CNCF graduated project that's built on top of Kubernetes. Helm is a Kubernetes package manager which helps bundle all K8s objects together. In this course, you’ll create small projects to learn about the basic concepts of Helm and gain hands-on experience in working with it. You’ll also learn how to design reusable Helm charts.

By the time you’re done with this course, you’ll be equipped with the skills required to make reliable, consistent, and scalable deployments with Helm. You’ll be able to use Helm to create, package, configure, and deploy your Kubernetes applications efficiently and effectively.

A Practical Guide to Helm

# What will be built

When we start to learn or test new things it’s fine to do everything locally (or here, in the interactive sandboxes). But in the real world, production-ready code won’t be running on our laptops. It will be running either on a private or public cloud.

There are plenty of public cloud providers. The most popular are AWS, Google Cloud, Microsoft Azure, and Alibaba Cloud. But a list of all the possible vendors is way longer. From this vast selection, we picked Google Cloud as our go-to cloud service for this course. The reason for that is it offers a free tier subscription that would allow us to create a small cluster without charging us anything.

If you’re lucky and work for a company that gives you a free Kubernetes cluster for testing or you happen to have one for your usage, you can easily go with that. Some of the configuration steps may be different for a different cluster.



# Create a Google Cloud project

The first step is to log in or create a new Google account. It can be done from the Google Cloud main page.

Next, we need to create a Google Cloud project, which plays the role of a workspace from where we can enable and configure many cloud services. 
 Then, go to [the project selector page](https://console.cloud.google.com/projectselector2/home/dashboard)  (remember to be logged in) and click the “Create Project” button.
