By default, Concourse will check your resources once per minute to see if they have updated. In order to reduce excessive checks, you must configure webhooks to trigger Concourse externally. This resource automatically configures your GitHub respoitories to send webhooks to your Concourse pipeline the instant a change happens.

Include the github-webhook-resource in your pipeline.yml file
resource_types:
- name: github-webhook-resource
type: docker-image
source:
repository: homedepottech/github-webhook-resource
tag: latest Now when you set your pipeline, you can optionally include instance variables that will be picked up by the resource. Here is a sample script that sets the pipeline for you.
#!/bin/sh
fly -t {your team name} sp -c pipeline.yml -p {your pipeline name} --instance-var {you instance variables}
The Concourse entrypoints are in bin/check, bin/in, and bin/out.js. You can add functionality to these files directly, or you can require additional supporing files.
