+# Smoke Test
+
+This lab walks you through a quick smoke test to make sure things are working.
+
+## Test
+
+```
+kubectl run nginx --image=nginx --port=80 --replicas=3
+```
+
+```
+deployment "nginx" created
+```
+
+```
+kubectl get pods -o wide
+```
+```
+NAME                     READY     STATUS    RESTARTS   AGE       IP           NODE
+nginx-2032906785-ms8hw   1/1       Running   0          21s       10.200.2.2   worker2
+nginx-2032906785-sokxz   1/1       Running   0          21s       10.200.1.2   worker1
+nginx-2032906785-u8rzc   1/1       Running   0          21s       10.200.0.2   worker0
+```
+
+```
+kubectl expose deployment nginx --type NodePort
+```
+
+```
+service "nginx" exposed
+```
+
+> Note that --type=LoadBalancer will not work because we did not configure a cloud provider when bootstrapping this cluster.
+
+Grab the `NodePort` that was setup for the nginx service:
+
+```
+export NODE_PORT=$(kubectl get svc nginx --output=jsonpath='{range .spec.ports[0]}{.nodePort}')
+```
+
+```
+gcloud compute firewall-rules create kubernetes-nginx-service \
+  --allow=tcp:${NODE_PORT} \
+  --network kubernetes
+```
+
+Grab the `EXTERNAL_IP` for one of the worker nodes:
+
+```
+export NODE_PUBLIC_IP=$(gcloud compute instances describe worker0 \
+  --format 'value(networkInterfaces[0].accessConfigs[0].natIP)')
+```
+
+Test the nginx service using cURL:
+
+```
+curl http://${NODE_PUBLIC_IP}:${NODE_PORT}
+```
+
+```
