Creating Knative default Broker as non admin user

Create a consuming service:

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: broker-display1
spec:
  template:
    spec:
      containers:
      - image: quay.io/matzew/event-display

The Source

Now, create a source. The ping source:

apiVersion: sources.knative.dev/v1alpha2
kind: PingSource
metadata:
  name: ping-source
spec:
  schedule: "*/1 * * * *"
  jsonData: '{"message": "Hello world!"}'
  sink:
    ref:
      apiVersion: eventing.knative.dev/v1beta1
      kind: Broker
      name: default

NOTE: The source emits events to a Broker, called default. This broker is not yet there, therefore we do not immediately see a pod for the source being created.

The Broker

In order to create the broker there are a few ways for the admin (TODO add link for all the other content).

However for a normal user, it is possible to create a default broker as well. The trick is to use the ``knative-eventing-injection: enable Annotation on the trigger object.

Apply the trigger:

apiVersion: eventing.knative.dev/v1beta1
kind: Trigger
metadata:
  annotations:
    knative-eventing-injection: enabled
  name: testevents-trigger
spec:
  broker: default
  subscriber:
    ref:
      apiVersion: serving.knative.dev/v1
      kind: Service
      name: broker-display1

Now, this will cause the two broker pods (filter and ingress) to come up. As well as the pod for the source, since it has now a reachable sink (the broker).

Pods will be like:

NAME                                                              READY   STATUS    RESTARTS   AGE
