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.

(Select all that apply.) Where can a Helm chart be located to be considered usable by a Helmfile? 

(Select all that apply.) Where can a Helm chart be located to be considered usable by a Helmfile?

None, only `helmfile sync` is deprecated.

None, only `helmfile apply` is deprecated.

The `helmfile apply` command can be used only when we install Helm releases for the first time; after that, helmfile sync should be used.

The `helmfile apply` command calculates the differences between the current and new release and upgrades only those releases which have changed, while `helmfile sync` installs a new revision each time we run it, irrespective of whether something has changed or not. 

What is the difference between the `helmfile sync` and `helmfile apply` commands?

What is the difference between the <code>helmfile sync</code> and <code>helmfile apply</code> commands?

all Helm releases in specific Kubernetes namespaces

all Helm releases with a specific global value set up in its `values.yaml` file
