Triggers in Harness CI are used to initiate the execution of Pipelines.
We can automate trigger execution of pipelines for Git events.
For example when a pull request or push event occurs on a Git repo the trigger is activated and it invokes the pipeline execution.
Triggers enable event driven continuous integration and support the practice of every commit building and/or deploying to a target environment.
