The gateway-route relation

The gateway-route interface is implemented by the charms.gateway_api_integrator.v1.gateway_route library. It is a bidirectional application databag exchange:

Direction	Fields	Description
Requirer → Provider	hostname, additional_hostnames	The FQDN(s) the workload should be reachable on. Used by the provider to request TLS certificates and DNS records.
Provider → Requirer	gateway_name, gateway_model, https_mode, gateway_address	The identity of the Gateway resource so the requirer can build HTTPRoute parentRefs.

The https_mode field tells the requirer how TLS is handled. The field has three available modes:

Mode	Meaning
disabled	No TLS configured; only HTTP listeners exist on the Gateway.
enabled	TLS configured; both HTTP and HTTPS listeners exist.
enforced	TLS configured and HTTP is redirected to HTTPS.
