## Challenge scenario
You are taking over ownership of a test environment and have been given an updated version of a containerized test application to deploy. Your systems' architecture team has started adopting a containerized microservice architecture. You are responsible for managing the containerized test web applications. You will first deploy the initial version of a test application, called `echo-app` to a Kubernetes cluster called `echo-cluster` in a deployment called `echo-web`.
Before you get started, open the navigation menu and select **Cloud Storage**. The last steps in the Deployment Manager script used to set up your environment creates a bucket.
Refresh the Storage browser until you see your bucket. You can move on once your Console resembles the following:
![bucket](./images/bucket.webp#center)
Check to make sure your GKE cluster has been created before continuing. Open the navigation menu and select **Kubernetes Engine** > **Clusters**.
Continue when you see a green checkmark next to `echo-cluster`:
![kubernetes cluster](./images/kubernetes_cluster.webp#center)
To deploy your first version of the application, run the following commands in Cloud Shell to get up and running:
```bash
gcloud container clusters get-credentials echo-cluster --zone=us-central1-a
```
```bash
kubectl create deployment echo-web --image=gcr.io/qwiklabs-resources/echo-app:v1
```
```bash
kubectl expose deployment echo-web --type=LoadBalancer --port 80 --target-port 8000
```
## Your challenge
You need to update the running `echo-app` application in the `echo-web` deployment from the v1 to the v2 code you have been provided. You must also scale out the application to 2 instances and confirm that they are all running.
1. Check that there is a tagged image in gcr.io for echo-app:v2.
```bash
mkdir echo-web
cd echo-web
gsutil cp -r gs://$DEVSHELL_PROJECT_ID/echo-web-v2.tar.gz .
tar -xzf echo-web-v2.tar.gz
rm echo-web-v2.tar.gz
docker build -t echo-app:v2 .
docker tag echo-app:v2 gcr.io/$DEVSHELL_PROJECT_ID/echo-app:v2
docker push gcr.io/$DEVSHELL_PROJECT_ID/echo-app:v2
```
2. Echo-app:v2 is running on the Kubernetes cluster.
Deploy the first version of the application.
```bash
gcloud container clusters get-credentials echo-cluster --zone=us-central1-a
kubectl create deployment echo-web --image=gcr.io/qwiklabs-resources/echo-app:v1
kubectl expose deployment echo-web --type=LoadBalancer --port 80 --target-port 8000
```
Edit the `deployment.apps` file.
```bash
kubectl edit deploy echo-web
```
Start the editor by type `i`. Change `image=...:v1` to `image=...:v2`.
`image=gcr.io/qwiklabs-resources/echo-app:v2`
Save the `deployment.apps` file, hit **ESC** then type `:wq` and **Enter**.
3. The Kubernetes cluster deployment reports 2 replicas.
```bash
kubectl scale deployment echo-web --replicas=2
```
4. The application must respond to web requests with V2.0.0.
```bash
kubectl expose deployment echo-web --type=LoadBalancer --port 80 --target-port 8000
kubectl get svc
```
## Congratulations!
