Migrating to the PingSource

With the release of 0.13 the CronJobsource is deprecated, and should be converted to the PingSource

Here is an example of a CronJobSource that delivers messages to a given sink:

apiVersion: sources.eventing.knative.dev/v1alpha1
kind: CronJobSource
metadata:
  name: cronjob-source
spec:
  schedule: "* * * * *"
  data: '{"message": "Hello world!"}'
  sink:
    apiVersion: eventing.knative.dev/v1alpha1
    kind: Broker
    name: default

Migration to the newer PingSource requires a few steps, and the sample now looks like:

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

Biggest impact on changes were:

• different GVK (see apiVersion/Kind diffs)
• spec now uses jsonData on the PingSource
