What is puppet_webhook

puppet_webhook is a Sinatra-based application receiving REST-based calls to trigger Puppet and r10k-related tasks such as:

  • Webhooks from Source Code systems to trigger r10k environment and module deploys
  • Send notifications via Slack


  • Ruby 2.5.0 or greater (since version 2. 1.x works with Ruby 2.4.0)
  • Puppet 5.5.0 or greater
  • r10k gem
  • Optional: MCollective and MCollective-r10k (Provides one form of multi-master syncronization)
    • Currently Mcollective-r10k is only available from puppet-r10k
    • If you don't want to use MCollective, you could install this webhook on each compile master instead


Legacy puppet_webhook (< 2.x)

Please see the pre-2.x documentation if using the old gem-based puppet_webhook.

Modern puppet_webhook (>= 2.x)


Add the Voxpupuli GPG key and repository:

wget -qO - "" | sudo apt-key add -
echo "deb $(awk -F= '/VERSION_CODENAME=/ {print $2}' /etc/os-release) main" | sudo tee -a /etc/apt/sources.list.d/voxpupuli.list
sudo apt update

Install puppet_webhook

sudo apt install puppet-webhook


Download the voxpupuli.repo file

wget -o voxpupuli.repo
sudo mv voxpupuli.repo /etc/yum.repos.d/voxpupuli.repo

Install puppet_webhook

yum install puppet-webhook

Docker Compose

Experience with Docker and Docker Compose are assumed. The Docker Compose setup expects that the Webhook API container volumes will have access to the codedir, either via NFS or on system.

  1. Download the sample docker-compose.yml file from the github repo:
$ wget -O docker-compose.yml
  1. Edit the image, environment, and volumes keys based on your own needs.
  2. run docker-compose up


This assumes you already have the correct Ruby version installed in the system or via a tool like rbenv, rvm, or asdf.

  1. Download the latest release from the Releases page.
  2. Extract the tarball into the desired directory:
$ tar -xzvf puppet_webhook-latest.tar.gz -C /opt/puppet_webhook
  1. Enter the install directory and install dependencies:
$ cd /opt/puppet_webhook && bundle install
  1. Start the process:
$ bundle exec puma


Puppet Webhook API configuration is maintained by the config.yml file in the APP_ROOT/config directory. Many options have sane defaults applied, but a few are required for base functionality.

Configure the webhook

This API provides two endpoints that need to be called:

  • /api/v1/r10k/module for every module
  • api/v1/r10k/environment for the control repository

In GitHub, set setup looks like this:

!GitHub Webook configuration

If you configured basic authentication, you need to add the username and password to the URL.
