The timer driver supports triggers only. It is used for configuring pipelines so that jobs run at scheduled times. No connection configuration is required.

Trgger Configuration

Timers don’t require a special connection or driver. Instead they can simply be used by listing timer as the trigger.

This trigger will run based on a cron-style time specification. It will enqueue an event into its pipeline for every project defined in the configuration. Any job associated with the pipeline will run in response to that event.


The timer trigger supports the following attributes:

pipeline.trigger.timer.time (required)

The time specification in cron syntax. Only the 5 part syntax is supported, not the symbolic names. Example: 0 0 * * * runs at midnight. The first weekday is Monday. An optional 6th part specifies seconds. The optional 7th part specifies a jitter in seconds. This advances or delays the trigger randomly, limited by the specified value. Example 0 0 * * * * 60 runs at midnight with a +/- 60 seconds jitter.
