format	value {\"time\":\"{{.LastTimestamp.Format \"2006-01-02T15:04:05.999\"}}\",\"involvedObjectKind\":\"{{.InvolvedObject.Kind}}\",\"involvedObjectNamespace\":\"{{.InvolvedObject.Namespace}}\",\"involvedObjectName\":\"{{.InvolvedObject.Name}}\",\"involvedObjectUid\":\"{{.InvolvedObject.UID}}\",\"involvedObjectApiVersion\":\"{{.InvolvedObject.APIVersion}}\",\"involvedObjectResourceVersion\":\"{{.InvolvedObject.ResourceVersion}}\",\"reason\":\"{{.Reason}}\",\"type\":\"{{.Type}}\",\"message\":\"{{js .Message}}\",\"kind\":\"Event\"}	Format to print Event.

Examples:

Note: It's just an example of a parameter's format, not a recommended parameter.

cloudEventsReader:
  install: true
  args:
    - "-workers=2"
    - "-namespace=logging"
    - "-namespace=monitoring"
    - "-format={\"time\":\"{{.LastTimestamp.Format \"2006-01-02T15:04:05Z\"}}\""

or you can set args without quoting:

cloudEventsReader:
  install: true
  args:
    - -namespace=logging
    - -namespace=monitoring
    - -format={"time":"{{.LastTimestamp.Format
      "2006-01-02T15:04:05.999"}}","involvedObjectKind":"{{.InvolvedObject.Kind}}","involvedObjectNamespace":"{{.InvolvedObject.Namespace}}","involvedObjectName":"{{.InvolvedObject.Name}}","involvedObjectUid":"{{.InvolvedObject.UID}}","involvedObjectApiVersion":"{{.InvolvedObject.APIVersion}}","involvedObjectResourceVersion":"{{.InvolvedObject.ResourceVersion}}","reason":"{{.Reason}}","type":"{{.Type}}","message":"{{js
      .Message}}","kind":"EventTEST"}

Note: If you want to set non-json format, do not forget to turn off filter in FluentBit/FluentD like this:

  fluentd:
    cloudEventsReaderFormat: text

This is an example of Event (API version events.k8s.io/v1).

{
   "message":"Created new replication controller \"postgres-backup-daemon-1\" for version 1",
   "kind":"KubernetesEvent",
   "log":{
      "firstTimestamp":"2018-11-02T02:26:00Z",
      "reason":"DeploymentCreated",
      "metadata":{
         "name":"postgres-backup-daemon.15632d8844761c5d",
         "namespace":"pg96-nighttest",
         "creationTimestamp":"2018-11-02T02:26:00Z",
         "uid":"a38df948-de46-11e8-9fdb-fa163e5f2c4f",
         "selfLink":"/api/v1/namespaces/pg96-nighttest/events/postgres-backup-daemon.15632d8844761c5d",
         "resourceVersion":"71608432"
      },
      "apiVersion":"v1",
      "involvedObject":{
         "namespace":"pg96-nighttest",
         "name":"postgres-backup-daemon",
         "uid":"a388d4aa-de46-11e8-9fdb-fa163e5f2c4f",
         "apiVersion":"v1",
         "kind":"DeploymentConfig",
         "resourceVersion":"71608172"
      },
      "lastTimestamp":"2018-11-02T02:26:00Z",
      "count":1,
      "source":{
         "component":"deploymentconfig-controller"
      },
      "type":"Normal"
   }
}

Formatted log output with default template of the example Event will be printed in stdout:

{"time":"2018-11-02T02:26:00.999"","involvedObjectKind":"DeploymentConfig","involvedObjectNamespace":"pg96-nighttest","involvedObjectName":"postgres-backup-daemon","involvedObjectUid":"a388d4aa-de46-11e8-9fdb-fa163e5f2c4f","involvedObjectApiVersion":"v1","involvedObjectResourceVersion":"71608172","reason":"DeploymentCreated","type":"Normal","message":"Created new replication controller \"postgres-backup-daemon-1\" for version 1","kind":"KubernetesEvent"}
