How do you filter events in Kabanero 0.6.3

[oiricaud]

Greetings! I want to understand how I can filter trigger events using kabanero. I currently have a pipeline that manages pipelines but I haven't been able to filter out a pipeline run based on the event. i.e I only want the pipeline run to get created on a push to the master branch. https://github.com/ibm-garage-ref-storefront/devops-pipelines

My work around to not get inifinite pipeline-runs I created another repository as a server.
