We'll block access to the Guestbook Service by adding the deny-guestbook-service.yaml
rule shown below.
kubectly apply -f istio/deny-guestbook-service.yaml
Visit Guestbook UI and see that Guestbook Service can no longer be accessed.
To remove denial, you can delete the rule.
kubectly delete -f istio/deny-guestbook-service.yaml
