The Zuul driver supports triggers only. It is used for triggering pipelines based on internal Zuul events.

Trigger Configuration

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


The Zuul trigger supports the following attributes:

pipeline.trigger.zuul.event (required)

The event name. Currently supported events:


When Zuul merges a change to a project, it generates this event for every open change in the project.


Triggering on this event can cause poor performance when using the GitHub driver with a large number of installations.


When Zuul enqueues a change into any pipeline, it generates this event for every child of that change.


Only available for parent-change-enqueued events. This is the name of the pipeline in which the parent change was enqueued.
