# Part 2: Using Pods

This is Part 2 of a multi-part, self-paced quick start exercise.

Note

This exercise requires MicroK8s. If you do not have these already installed and running, see "[Prerequisites](https://docs.rafay.co/learn/quickstart/kubernetes/prerequisites/)".

## Using Pods

Pods are the smallest deployable units of computing that you can create and manage in Kubernetes. For this exercise, you will deploy BusyBox, a small Docker image.

### Pod YAML file

You can also create a pod using a YAML file, which is a configuration file. You could create a YAML file from the command line, but for this exercise, you can just use a text editor. Or you can download the pod YAML file from this public [Git repository](https://github.com/RafaySystems/getstarted/tree/master/kubernetes).

1. Open the Terminal.
2. Navigate to the Downloads folder.

```
   cd ./Downloads
   ```

3. Use the following command to create an empty YAML file in your Downloads folder.

```
   touch pod.yaml
   ```

4. Use the nano text editor in the Terminal.

```
   nano pod.yaml
   ```

5. Copy and paste the configuration below into the text editor.
6. Press **Cmd + X**, then type **Y** and press **Return** to save the pod.yaml file.

### Add a Pod

1. In the Terminal or Command Prompt, get a list of all the pods in your environment.

```
   microk8s kubectl get pods -A
   ```

2. Use the following command to add the pod to your environment using a YAML file.

```
   microk8s kubectl create -f pod.yaml
   ```

3. List the pods in your environment. The "busybox-sleep" image has been added as a pod.

```
   microk8s kubectl get pods -A
   ```

## pod.yaml

```yaml
apiVersion: v1
kind: Pod
metadata:
  name: busybox-sleep
spec:
  containers:
  - name: busybox
    image: busybox
    args:
    - sleep
    - "1000"
```
