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

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.
