For Task 1, the first image is incorrect. It shows nginx in the ingress-nginx namespace. The current version of Simplify Microservices Lab has deployed nginx into the msdataworkshop namespace

A better way to illustrate the success of kubectl create -f ext-order-ingress.yaml -n msdataworkshop is to show the ingress because that is what is being created

doug_drech@cloudshell:k6 (us-phoenix-1)$ kubectl get ingress -A NAMESPACE NAME CLASS HOSTS ADDRESS PORTS AGE msdataworkshop grabdish-ext-order-ingress * 152.70.129.118 80, 443 170m msdataworkshop grabdish-frontend-ingress * 152.70.129.118 80, 443 9d
