# Gateway sources | ||
|
||
The gateway-grcproute, gateway-httproute, gateway-tcproute, gateway-tlsroute, and gateway-udproute | ||
sources create DNS entries based on their respective `gateway.networking.k8s.io` resources. | ||
|
||
## Filtering the Routes considered | ||
|
||
These sources support the `--label-filter` flag, which filters *Route resources | ||
by a set of labels. | ||
|
||
## Domain names | ||
|
||
To calculate the Domain names created from a *Route, this source first collects a set | ||
of [domain names from the *Route](#domain-names-from-route). | ||
|
||
It then iterates over each of the `status.parents` with | ||
a [matching Gateway](#matching-gateways) and at least one [matching listener](#matching-listeners). | ||
For each matching listener, if the | ||
listener has a `hostname`, it narrows the set of domain names from the *Route to the portion | ||
that overlaps the `hostname`. If a matching listener does not have a `hostname`, it uses | ||
the un-narrowed set of domain names. | ||
|
||
### Domain names from Route | ||
|
||
The set of domain names from a *Route is sourced from the following places: | ||
|
||
* If the *Route is a GRPCRoute, HTTPRoute, or TLSRoute, adds each of the`spec.hostnames`. | ||
|
||
* Adds the hostnames from any `external-dns.alpha.kubernetes.io/hostname` annotation on the *Route. | ||
This behavior is suppressed if the `--ignore-hostname-annotation` flag was specified. | ||
|
||
* If no endpoints were produced by the previous steps | ||
or the `--combine-fqdn-annotation` flag was specified, then adds hostnames | ||
generated from any`--fqdn-template` flag. | ||
|
||
* If no endpoints were produced by the previous steps, each | ||
attached Gateway listener will use its `hostname`, if present. | ||
|
||
### Matching Gateways | ||
|
||
Matching Gateways are discovered by iterating over the *Route's `status.parents`: | ||
|
||
* Ignores parents with a `parentRef.group` other than | ||
`gateway.networking.k8s.io` or a `parentRef.kind` other than `Gateway`. | ||
|
||
* If the `--gateway-namespace` flag was specified, ignores parents with a `parentRef.namespace` other | ||
than the specified value. | ||
|
||
* If the `--gateway-label-filter` flag was specified, ignores parents whose Gateway does not match the | ||
specified label filter. | ||
|
||
* Ignores parents whose Gateway either does not exist or has not accepted the route. | ||
|
||
### Matching listeners | ||
|
||
Iterates over all listeners for the parent's `parentRef.sectionName`: | ||
|
||
* Ignores listeners whose `protocol` field does not match the kind of the *Route per the following table: | ||
|
||
| kind | protocols | | ||
|------------|-------------| | ||
| GRPCRoute | HTTP, HTTPS | | ||
| HTTPRoute | HTTP, HTTPS | | ||
| TCPRoute | TCP | | ||
| TLSRoute | TLS | | ||
| UDPRoute | UDP | | ||
|
||
* If the parent's `parentRef.port` port is specified, ignores listeners without a matching `port`. | ||
|
||
* Ignores listeners which specify an `allowedRoutes` which does not allow the route. | ||
|
||
## Targets | ||
|
||
The targets of the DNS entries created from a *Route are sourced from the following places: | ||
|
||
1. If a matching parent Gateway has an `external-dns.alpha.kubernetes.io/target` annotation, uses | ||
the values from that. | ||
|
||
2. Otherwise, iterates over that parent Gateway's `status.addresses`, | ||
adding each address's `value`. | ||
|
||
The targets from each parent Gateway matching the *Route are then combined and de-duplicated. |
