Follow the steps at:

Multiple invocations of the webapp endpoint shows that the hello greeting service is not healthy. Here is the output:

~ $ curl http://$(kubectl get svc/webapp -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
no healthy upstream Sheldon~ $ curl http://$(kubectl get svc/webapp -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
