1.4.1 Triggers

In this article, you will know what a trigger is, its usage, and how to add a trigger to a pipeline. To know more about trigger development, see the Plugins section of the documentation.

What is a Trigger?

A trigger is an initial input that starts off the pipeline execution. It is an event listener such as a webhook catcher. Whenever the event throws a webhook, the trigger catches it and executes the pipeline.

Where are Triggers needed?

Depending on the webhooks, Triggers can listen to any event. A common event example is a code commit into the GIT repository where a CI/CD automation may be evoked. Other events such as monitoring peaks, firewall attacks, etc. can also cause a pipeline to start running.

Adding a Trigger to a pipeline

1. Open the project and pipeline where you want to add the trigger to.

2. In the Design sub-menu, click the Triggers icon to enable the Triggers panel.

3. In the Triggers panel, click the Create New button.
