Calendar¶

Calendar event-source generates events on either a cron schedule or an interval and helps sensor trigger workloads.

Event Structure¶

The structure of an event dispatched by the event-source over the eventbus looks like following,

    {
        "context": {
          "type": "type_of_event_source",
          "specversion": "cloud_events_version",
          "source": "name_of_the_event_source",
          "id": "unique_event_id",
          "time": "event_time",
          "datacontenttype": "type_of_data",
          "subject": "name_of_the_configuration_within_event_source"
        },
        "data": {
          "eventTime": {/* UTC time of the event */},
          "userPayload": { /* static payload available in the event source */},
        }
    }

Specification¶

Calendar event-source specification is available here.

Setup¶

Install the event source in the argo-events namespace.

kubectl apply -n argo-events -f https://raw.githubusercontent.com/argoproj/argo-events/stable/examples/event-sources/calendar.yaml

The event-source will generate events at every 10 seconds. Let's create the sensor.

kubectl apply -n argo-events -f https://raw.githubusercontent.com/argoproj/argo-events/stable/examples/sensors/calendar.yaml

Once the sensor pod is in running state, wait for next interval to occur for sensor to trigger workflow.
