Trigger filtering based on cloud event headers

[Andrey Stelmashenko]

Hi Community,

There is a filters feature of Triggers. Here is an example:

```

apiVersion: eventing.knative.dev/v1 kind: Trigger metadata: name: my-service-trigger spec: broker: default filter: attributes: type: dev.knative.foo.bar myextension: my-extension-value subscriber: ref: apiVersion: serving.knative.dev/v1 kind: Service name: my-service

```

Cloud events 'type' header is actually 'ce-type', how should I specify attributes 'type' or 'ce-type?'

Hi Andrey

The Cloud Events Attribute is called "type" and that's what you should use. https://github.com/cloudevents/spec/blob/v1.0.2/cloudevents/spec.md#type

Thanks

Hi Andrey,

it is any CloudEvent context attribute [1], in this case `type` (or
`myextension`).
