+## Challenge scenario
+
+Your development team is interested in adopting a containerized microservices approach to application architecture. You need to test a sample application they have provided for you to make sure that that it can be deployed to a Google Kubernetes container. The development group provided a simple Go application called `echo-web` with a Dockerfile and the associated context that allows you to build a Docker image immediately.
+
+## Your challenge
+
+To test the deployment, you need to download the sample application, then build the Docker container image using a tag that allows it to be stored on the Container Registry. Once the image has been built, you'll push it out to the Container Registry before you can deploy it.
+
+With the image prepared you can then create a Kubernetes cluster, then deploy the sample application to the cluster.
+
+1. An application image with a v1 tag has been pushed to the gcr.io repository
+
+    ```bash
+    mkdir echo-web
+    cd echo-web
+    gsutil cp -r gs://$DEVSHELL_PROJECT_ID/echo-web.tar.gz .
+    tar -xzf echo-web.tar.gz
+    rm echo-web.tar.gz
+    cd echo-web
+    docker build -t echo-app:v1 .
+    docker tag echo-app:v1 gcr.io/$DEVSHELL_PROJECT_ID/echo-app:v1
+    docker push gcr.io/$DEVSHELL_PROJECT_ID/echo-app:v1
+    ```
+
+2. A new Kubernetes cluster exists (zone: us-central1-a)
+
+    ```bash
+    gcloud config set compute/zone us-central1-a
+
+    gcloud container clusters create echo-cluster --num-nodes=2 --machine-type=n1-standard-2
+    ```
+
+3. Check that an application has been deployed to the cluster
+
+    ```bash
+    kubectl create deployment echo-web --image=gcr.io/$DEVSHELL_PROJECT_ID/echo-app:v1
+    ```
+
+4. Test that a service exists that responds to requests like Echo-app
+
+    ```bash
+    kubectl expose deployment echo-web --type=LoadBalancer --port 80 --target-port 8000
+    ```
