Kubernetes helps deploy and manage containerized applications at scale. It abstracts the underlying infrastructure so it doesn’t matter if you're deploying your applications to Amazon Web Services, Microsoft Azure, or your own on-premises datacenter. Ready to get started?

In this course, you will cover the most essential Kubernetes concepts that you’ll need to know to be proficient, including pods, services, and deployments. Beyond that though, you will learn about the Kubernetes architecture, how to build clusters, and how to deploy and manage applications. 

In the last part of the course, you will dive into threat modeling and real-world security practices. By the end of this course, you will have a great new skill for your resume and you’ll be able to start using Kubernetes in your own projects.

Learn Kubernetes: A Deep Dive

 It tells Kubernetes the type of object being deployed.

It is where you attach a name and labels.

It is where you define the containers that will run in the Pod.

What is the purpose of the `.kind` field in manifest files?

What is the purpose of the <code>.kind</code> field in manifest files?

It tells Kubernetes the type of object being deployed.

What is the purpose of the `.metadata` field in manifest files?

What is the purpose of the <code>.metadata</code> field in manifest files?

```shell
$ kubectl manifest -f pod.yml
```

Which command will `POST` pod.yml to the API server?

Which command will <code>POST</code> pod.yml to the API server?

`.spec` = desired state

`.status` = current state

`.spec` = current state

`.status` = desired state

`.spec` = predicted state

`.status` = current state

`.spec` = specialized state

`.status` = current state

Below is a snipped output of the `$ kubectl get pods hello-pod -o yaml` command.


```shell
apiVersion: v1
kind: Pod
metadata:
  ...
spec:  
  containers:
   ...
status:  
  conditions:
   ...
.
.
.
```

What do `.spec` and `.status` represent?

Below is a snipped output of the <code>$ kubectl get pods hello-pod -o yaml</code> command.
<pre><code class="language-shell">apiVersion: v1
kind: Pod
metadata:
 ...
spec: 
 containers:

status: 
 conditions:

.
.
.
</code></pre>
What do <code>.spec</code> and <code>.status</code> represent?

Which command will delete the Pod deployed from pod.yml?

Which command will delete the Pod deployed from pod.yml?

The command will execute against the first container in the Pod.

The command will execute against the last used container in the Pod.

The command will execute a random container in the Pod.

While running multi-container Pods, you forgot to pass the `kubectl exec` command the `--container` flag and the name of the container. What will happen?
