After validating the potential impact of your policy and analyzing the results, you can make changes to the policy you want to deploy or to the configuration of your cluster before you are ready to start enforcing a policy. Once you are satisfied with the pre-deployment validation results, you can enforce the policy by clicking the Publish icon.
To enforce the policy:
Change the Ingresses: Restrict Hostnames rule from Monitor to Enforce and then click Publish changes in the top section of the right pane.
Confirm enforcement by clicking Publish changes.
Try to recreate the
ingress initechby deleting the existing one and creating it again with the following commands.
kubectl delete ingress initech.
kubectl apply ingress initech.
Verify the error message from the API server saying that this new ingress conflicts with the other two.
