Running a Node.js Container on Google Kubernetes Engine

Set Compute Zone

gcloud config set compute/zone us-central1-a

Create a New Cluster

gcloud container clusters create hello-world

You will use Project ID in many of the commands in this lab. The Project ID is conveniently stored in an environment variable in Cloud Shell. You can see it here:
```
echo $DEVSHELL_PROJECT_ID
```

Run the following to clone the samples:

git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git

Change directories:

cd nodejs-docs-samples/containerengine/hello-world/

Docker containers are built using a Dockerfile. The sample code provides a basic Dockerfile that we can use.
```
cat Dockerfile
```

Run the following command to publish your container image:

gcloud docker -- push gcr.io/$DEVSHELL_PROJECT_ID/hello-node:1.0

Create the pod using kubectl:

kubectl create deployment hello-node --image=gcr.io/$DEVSHELL_PROJECT_ID/hello-node:1.0

Run the following to expose the deployment with the kubectl expose command:

kubectl expose deployment hello-node --name=hello-node --type=LoadBalancer --port=80 --target-port=8080

To get the IP address for your service, run the following command:
```
kubectl get svc hello-node
```
Open a new browser window or tab and navigate to the external IP address from the previous step. You should see the sample code up and running!
