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.

What does each part of the following command mean?

```

Where: 
1: `dashboard`
2: `kubernetes`
3: `kuberentes-dashboard`
4: `-n dashboard`


What does each part of the following command mean?
<pre><code>helm install dashboard kubernetes/kubernetes-dashboard -n dashboard
</code></pre>
Where:

None. Helm will figure it out and install a new release if it doesn’t exist.

What flag needs to be added to the helm upgrade command if we want to use it when we install a Helm release for the first time?

What flag needs to be added to the helm upgrade command if we want to use it when we install a Helm release for the first time?

We’ll have an error because it’s not possible to set the same property two times in a command.

In the `values.yaml` file of a Helm chart there is a property called `replicaCount`, which defines how many Pods will be created. If we pass the following flags in the installation command, how many Pods will we have?
```
> helm install --set replicaCount=2 --set replicaCount=3 app ./app
```

In the <code>values.yaml</code> file of a Helm chart there is a property called <code>replicaCount</code>, which defines how many Pods will be created. If we pass the following flags in the installation command, how many Pods will we have?
<pre><code>&gt; helm install --set replicaCount=2 --set replicaCount=3 app ./app
</code></pre>

It will try to upgrade a Helm release, but if it fails it will roll back to the previous revision.

It will create a temporary release that’s deployed along the main one, which can then be used for testing.

It will run tests after making an upgrade.

It will simulate and check if a new revision will be installed.

What will happen to `helm upgrade` when we add the  `--dry-run` flag?

What will happen to <code>helm upgrade</code> when we add the <code>--dry-run</code> flag?
