Triggering On a Time Schedule

A common practice for many organizations is to perform regular nightly builds during off-peak usage hours. For example, you may wish to execute the run of pipeline every night at 3:00am.

To trigger at a specific time or at regular time intervals, use the CronTrigger resource to specify the time or interval. In this resource you can specify a cron expression string. When you specify the CronTrigger resource as an inputresource to the first step in a pipeline, the pipeline will automatically commence execution at that time or interval.

resources:
  - name: cron_trigger
    type: CronTrigger
    configuration:
      interval: '*/5 * * * *'     # Every 5 minutes

pipelines:      
  - name: pipeline_scheduled_triggers
    steps:
      - name: step_1
        type: Bash
        configuration:
          inputResources:
            - name: cron_trigger
        execution:
          onExecute:
            - printenv
