To get ready to use Pixie to debug an application on a Kubernetes cluster, we will deploy a demo microservices app named **TinyHat.me**, a simple API that provides virtual hats.

### Working with EKS

Lets download and deploy the Tiny Hats Application. 

First run the bash command to download the kubefiles 
```bash
wget -q -O tmp.zip https://tinyhatkubefiles.s3.us-west-2.amazonaws.com/tinyhats.zip && unzip tmp.zip && rm tmp.zip
```

To apply the exported environment variables, run

```bash 
cd ~/environment/tinyhats/0-setup
for f in *.yaml; do envsubst < $f | kubectl apply -f -; done
```

Then, run
```bash 
kubectl get pods --watch
```  
to see when everything is finished spinning up.

{{% notice warning %}}
You may notice the fetch service on a Crash Loop. This is completely normal because it takes MySQL a few minutes to spin up.

### You're done! 🎉
`tinyhats` should now be up and running! All your pods are ready to roll once you see this output from the command 
```bash
kubectl get pods --watch
```

```
tinyhats:~/environment/tinyhats $ kubectl get pods --watch

Finally, run

```bash
kubectl get services
```

Export the URLs associated with the `Gateway-Service` by running. Make sure to replace `<YOUR_DATA_GOES_HERE>` with your Gateway Service `EXTERNAL-IP` from above.

```bash
export GATEWAYSERVICE=<YOUR_GATEWAY_GOES_HERE>
```

Try pasting the URL for `Frontend-Service` in the browser. You should be greeted with the wonderful face of Bob Ross. Keep this URL handy as you will need it later in the workshop.
