### Sink parameter
Sink is a reference to an object that resolves to a URI to use as the sink.
A `sink` definition supports the following fields:
| Field | Description | Required or optional |
|-------|-------------|----------------------|
| `ref` | This points to an Addressable. | Required if _not_ using `uri` |
| `ref.apiVersion` | API version of the referent. | Required if using `ref` |
| [`ref.kind`][kubernetes-kinds] | Kind of the referent. | Required if using `ref` |
| [`ref.namespace`][kubernetes-namespaces] | Namespace of the referent. If omitted this defaults to the object holding it. | Optional |
| [`ref.name`][kubernetes-names] | Name of the referent. | Required if using `ref` |
| `uri` | This can be an absolute URL with a non-empty scheme and non-empty host that points to the target or a relative URI. Relative URIs are resolved using the base URI retrieved from Ref. | Required if _not_ using `ref` |
!!! note
At least one of `ref` or `uri` is required. If both are specified, `uri` is
resolved into the URL from the Addressable `ref` result.
#### Example: Sink parameter
Given the following YAML, if `ref` resolves into
`"http://mysink.default.svc.cluster.local"`, then `uri` is added to this
resulting in `"http://mysink.default.svc.cluster.local/extra/path"`.
<!-- TODO we should have a page to point to describing the ref+uri destinations and the rules we use to resolve those and reuse the page. -->
```yaml
apiVersion: sources.knative.dev/v1
kind: ApiServerSource
metadata:
name: <apiserversource>
namespace: <namespace>
spec:
...
sink:
ref:
apiVersion: v1
kind: Service
namespace: default
name: mysink
uri: /extra/path
```
!!! contract
This results in the `K_SINK` environment variable being set on the sink container
as `"http://mysink.default.svc.cluster.local/extra/path"`.
