+Sets the `regex_priority` setting to this value on the Kong route associated
+with the Ingress resource. This controls the [matching evaluation
+order](https://docs.konghq.com/latest/proxy/#evaluation-order) for regex-based
+routes. It accepts any integer value. Routes are evaluated in order of highest
+priority to lowest.
+
+Sample usage:

+
+Sets the `host_header` setting on the Kong upstream created to represent a

+address of an individual target (the Pod IP for controller-managed
+configuration). This annotation overrides the default behavior and sends
