If the change is a dynamic runtime configuration, it probably belongs in the [MeshConfig API](https://github.com/istio/api/blob/master/mesh/v1alpha1/config.proto).
This allows configuration without re-installing or restarting deployments.

If the change is to a Kubernetes field (such as modifying a Deployment attribute), it will likely need to be install-time configuration.

### Gateways

A cluster may use multiple Gateways, each with a different load balancer IP, domains and certificates.
