Zuul

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.

pipeline.trigger.zuul

The Zuul trigger supports the following attributes:

pipeline.trigger.zuul.event (required)

The event name. Currently supported events:

project-change-merged

When Zuul merges a change to a project, it generates this event for every open change in the project. If there are a large number of open changes, this may produce a large number of events and result in poor performance.

Warning

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

parent-change-enqueued

When Zuul enqueues a change into any pipeline, it generates this event for every child of that change. If there are a large number of open changes, this may produce a large number of events and result in poor performance.

Note

The dependent pipeline manager automatically enqueues forward, reverse, and if configured, circular dependencies of any change that is enqueued. It is not necessary to add this trigger to gate pipelines.

pipeline.trigger.zuul.pipeline

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