Ingress

Verrazzano uses NGINX for ingress to Verrazzano system components and Istio for application ingress. You can customize the NGINX and Istio ingress installation configurations using Helm overrides specified in the Verrazzano custom resource. For example, the following Verrazzano custom resource overrides the shape of an Oracle Cloud Infrastructure load balancer for both NGINX and Istio ingresses.
