Build Status

Available under the MIT license.


  1. Create a testing sandbox repository on GitHub and, from the CocoaPods specification repository, add the Gemfile and Rakefile files.

  2. Install PostgreSQL. (On OS X you can use the Postgres App.)

  3. Install the dependencies:

     $ rake bootstrap
  4. Run the travis before script to set up your db

     $ ./.travis/
  5. Test whether or not a pod sends correctly

     $ ./bin/test-push localhost:4567 spec/fixtures/AFNetworking.podspec


To start a development server run the following command, replacing the environment variables with your GitHub credentials, a GitHub testing sandbox repository, and a SHA hashed version of the password for the admin area (in this example the password is ‘secret’):

env RACK_ENV=development \
    GH_USERNAME=alloy GH_TOKEN=secret GH_REPO=alloy/ \
    TRUNK_APP_PUSH_ALLOWED=true TRUNK_APP_ADMIN_PASSWORD=2bb80d537b1da3e38bd30361aa855686bde0eacd7162fef6a25fe97bf527a25b \
    rake serve

Optional environment variables are:

  • RACK_ENV: Can be test, development, or production.
  • DATABASE_URL: The URL to the PostgreSQL database.


The webhook sends messages to other services when events in trunk happen.

These events trigger the webhook and send a message.

  • Successful create of a pod: {'type':'pod','action':'create','timestamp':'<date>','data_url':'<URL>'}
  • Successful create of a version: {'type':'version','action':'create','timestamp':'<date>','data_url':'<URL>'}
  • Successful update of a spec: {'type':'spec','action':'update','timestamp':'<date>','data_url':'<URL>'}

Environment variables are:

  • OUTGOING_HOOK_PATH: The garbled path used at the end of <schema>://<domain>/hooks/trunk/<OUTGOING_HOOK_PATH>.
  • WEBHOOKS_ENABLED: If set to true, the webhook is enabled.

Usage in Trunk





Trigger a message explicitly:

Webhook.pod_created(created_at, data_url)
Webhook.version_created(created_at, data_url)
Webhook.spec_updated(updated_at, data_url)

Change the webhook service URLs with the hook config methods:

Webhook.pod_created = [urls]
Webhook.version_created = [urls]
Webhook.spec_updated = [urls]

Check if it is enabled:


Usage in interested web services

Note: The webhooks are currently only available to CP internal services. We are looking into opening them up for public use after some intensive testing.

  1. Add your URL wherever one of the hook config methods (see above) is called (currently in ìnit.rb).
  2. We recommend you add OUTGOING_HOOK_PATH to the path to at least obscure your path.
  3. Install a POST route in your service that corresponds to the URL. Note: You MUST NOT use the value in OUTGOING_HOOK_PATH inside your public code. Instead, use an ENV variable as well, and set it to correspond to OUTGOING_HOOK_PATH.

You'll then receive POSTs to the URL with content message=<JSON data>.
