PingSource broken when created before the KSVC

[matzew]

Describe the bug

create a ping source before a ksvc, and notice that it will never go to READY state.

pingsource.sources.knative.dev/test-ping-source    False   NotFound          4m

Expected behavior

once the ksvc is there, it should go to ready state.

To Reproduce

1. Install eventing first
2. Creates a pingsource
3. Install Serving
4. Creates a ksvc
5. Creates a new PingSource
6. Creates a new ksvc
7. Notice that none of the PingSources becomes Ready

Knative release version

• 0.13
• 0.14

Additional context

here is the yamls, I used:

• ping.yaml:

apiVersion: sources.knative.dev/v1alpha2
kind: PingSource
metadata:
  name: test-ping-source
spec:
  schedule: "*/2 * * * *"
  jsonData: '{"message": "Hello world!"}'
  sink:
    ref:
      apiVersion: serving.knative.dev/v1
      kind: Service
      name: event-display

• ksvc.yaml:

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: event-display
spec:
  template:
    spec:
      containers:
        - image: quay.io/openshift-knative/knative-eventing-sources-event-display:v0.13.2

• ping2.yaml:

apiVersion: sources.knative.dev/v1alpha2

  jsonData: '{"message": "Hello world!"}'
  sink:
    ref:
      apiVersion: serving.knative.dev/v1
      kind: Service
      name: event-display2

• ksvc2.yaml:

In the eventing controller log I see something like:

{
  "level": "info",
  "ts": "2020-04-15T12:46:25.361Z",
  "logger": "controller.event-broadcaster",
  "caller": "record/event.go:274",
  "msg": "Event(v1.ObjectReference{Kind:\"PingSource\", Namespace:\"default\", Name:\"test-ping-source2\", UID:\"9c85dc7b-fc75-438d-8f0a-3c5973afd4fd\", APIVersion:\"sources.knative.dev/v1alpha1\", ResourceVersion:\"1931\", FieldPath:\"\"}): type: 'Warning' reason: 'SinkNotFound' Sink not found: {\"ref\":{\"kind\":\"Service\",\"namespace\":\"default\",\"name\":\"event-display2\",\"apiVersion\":\"serving.knative.dev/v1\"}}",
  "commit": "02bc516"
}

[matzew]

the ksvc objects are READY:

 k get ksvc
NAME             URL                                         LATESTCREATED          LATESTREADY            READY   REASON
event-display    http://event-display.default.example.com    event-display-rntw2    event-display-rntw2    True    
event-display2   http://event-display2.default.example.com   event-display2-rwscr   event-display2-rwscr   True    

but the not so the sources:

k get sources
NAME                                               READY   REASON     SINK   AGE
pingsource.sources.knative.dev/test-ping-source    False   NotFound          14m
pingsource.sources.knative.dev/test-ping-source2   False   NotFound          12m

when I kill the eventing controller pod,

the sources are correctly reconciled and eventually will be true. but only when I kill the pod...

[n3wscott]

The first failure is expected. The watch on the ksvc kind fails.

Why it does not recover with the new source is interesting...

[lionelvillard]

@matzew this scenario works with mtping because the receive adapter is created after the sink existence check. However there is no sink tracker, strange...

I'm getting a similar behavior on 0.16:

source.yaml:

apiVersion: sources.knative.dev/v1alpha2
kind: PingSource
metadata:
  name: source
spec:
  schedule: "* * * * *"
  jsonData: '{"message": "Hello world from ping!"}'
  sink:
    ref:
      apiVersion: serving.knative.dev/v1
      kind: Service
      name: service

service.yaml:

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: service
spec:
  template:
    spec:
      containers:
        - image: docker.io/meteatamel/event-display:v1

Is there a solution to this problem ? I am using camel k and have the same issue. These are the steps I am doing.

echo "Creating the event watcher service account"
envsubst < createEventsSA.yaml | oc apply -f -
echo "Creating the event watcher role"
envsubst < eventWatcherRole.yaml | oc apply -f -
echo "Creating the event watcher role binding"
envsubst < eventWatcherRoleBinding.yaml | oc apply -f -
echo "Creating the event watcher channel"
envsubst < eventWatcherChannel.yaml | oc apply -f -
echo "Creating the event watcher apiserversource"
envsubst < eventWatcherapiserversource.yaml | oc apply -f -

and then I start the service but facing the same issue.
