webhookd

A very simple webhook server to launch shell scripts.

It can be used as a cheap alternative of Docker hub in order to build private Docker images.

Installation

Linux binaries for release 0.0.1

• amd64

Download the version you need, untar, and install to your PATH.

$ wget https://github.com/ncarlier/webhookd/releases/download/v0.0.1/webhookd-linux-amd64-v0.0.1.tar.gz
$ tar xvzf webhookd-linux-amd64-v0.0.1.tar.gz
$ ./webhookd

Usage

Create your own scripts template in the scripts directory.

Respect the following structure:

/scripts
|--> /bitbucket
  |--> /echo.sh
  |--> /build.sh
|--> /github
|--> /docker

The directory name right under the scripts directory defined the hookname.

For now, supported hooks are:

• GitHub
• Gitlab
• Bitbucket
• Docker Hub

The scripts under the hook directory defined the actions.

The action script take parameters. These parameters are extract from the payload of the hook. For instance the GitHub hook extract the repository URL and name. Then pass them by parameter to the action script.

Check the scripts directory for samples.

Once the action script created, you can trigger the webhook :

$ curl -H "Content-Type: application/json" \
    --data @payload.json \
    http://localhost:8080/<hookname>/<action>

The action script's output is collected and sent by email or by HTTP request.

The HTTP notification need some configuration:

• APP_NOTIFIER=http
• APP_NOTIFIER_FROM=webhookd noreply@nunux.org
• APP_NOTIFIER_TO=hostmaster@nunux.org
• APP_HTTP_NOTIFIER_URL=http://requestb.in/v9b229v9

Note that the HTTP notification is compatible with Mailgun API.

As the smtp notification:

• APP_NOTIFIER=smtp
• APP_SMTP_NOTIFIER_HOST=localhost:25
