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.

Create or delete a webhook using the configured parameters.

org
: Required. Your github organization.repo

: Required. Arbitrary string to identify your webhook. Must match thewebhook_token
property of the resource your webhook points to.operation

to delete an existing webhook. Outputs current timestamp on non-existing webhooks.
events
: Optional. An array of events which will trigger your webhook. Default:push
pipeline
: Optional. Defaults to the name of the pipeline executing the taskpipeline_instance_vars
: Optional. Instance vars to append to the webhook url. These help Concourse identify which instance pipeline it should invokepayload_base_url
: Optional. The base URL to send the webhook payload to. Defaults to the external Concourse URL of the pipeline executing the task.payload_content_type
: Optional. Default:json
json
to serialize payloads to JSON.form
to serialize payloads to x-www-form-urlencoded.
payload_secret
: Optional. Secret that is used as the key to generate delivery signature headers, if the destination requires it for delivery validation.
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.
See the Reference section for some helpful information related to this project's implementation.

Before submitting your changes for review, ensure all tests are passing.
docker build -t github-webhook-resource .
To use the newly built image, push it to a Docker repository which your Concourse pipeline can access and configure your pipeline to use it:
docker tag github-webhook-resource example.com/github-webhook-resource
docker push example.com/github-webhook-resource
