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

# Spin up a cluster

Starting from now we’ll move to a terminal and use the `gcloud` tool. To install Google Cloud CLI, please follow the steps mentioned in the following links (depending on your machine):


* For macOS,  [please use this link](https://www.educative.io/answers/how-to-install-google-cloud-cli-on-macos).
* For Linux, [please use this link](https://www.educative.io/answers/how-to-install-google-cloud-cli-on-linux).
* For Debian/Ubuntu, [please use this link](https://www.educative.io/answers/how-to-install-google-cloud-cli-on-debian-ubuntu).
* For Windows, [please use this link](https://www.educative.io/answers/how-to-install-google-cloud-cli-on-windows).

Also, to log in and use your account, run the following command:



The first thing to do is to configure our `gcloud` tool to be connected with the right project, as follows:




gcloud config set project [your project id]
Updated property [core/project].

gcloud config set compute/region [your region id]
Updated property [compute/region].

gcloud config set compute/zone [your zone]
Updated property [compute/zone].

And here is the explanation for some of the inputs:

* `[your project id]`:This is the ID of a project, not its name. We can find it by running the`gcloud projects list` command.
* `[your region id]` : This is the default region in which we want to spin up our cluster. Select the region which is the closest to your location, e.g., europe-central2.
*  `[your zone]`:This is the default zone. Here, select the zone which is a part of your region, e.g., europe-central2-a.

A list of all the available regions and zones can be found in  [the official documentation](https://cloud.google.com/compute/docs/regions-zones).

> **Note:** When we spin up our cluster, Google will start to measure the usage of their resources and charge us for it. To make sure that doesn’t happen, we need to delete it after using it. To track our spending we can go to the Billing page.

Instructions on how to remove a cluster are given in this lesson in “Deleting a GKE cluster.”


Now that we’re aware of the precautions, we can proceed with creating an Autopilot cluster with the name `kanban-cluster`, which may take several minutes.
