Chicken Little

A RESTful service to get ahold of people, quickly.

Uses phone calls, SMS, and e-mail to send short messages to people registered with the service.
Allows for per-user configurable contact plans (e.g., "Send me an SMS. If I don't reply within five minutes, call me on the phone. If I don't answer, keep calling back every ten minutes until I do.").
Uses Twilio and Mailgun (or your own SMTP server) to handle the contacting.

Requirements

You'll need a Twilio account if you want to notify by voice and/or SMS. You'll need a Mailgun account or a SMTP server if you want to notify by e-mail.

API

People API - used for adding and deleting people in the system.
Notification Plan API - used to define how people are notified (contact methods, order, and timing)
Notification API - used to send notifications to a person using their notification plan

Quick Start

You'll need Go installed to build the binary.
Fetch and build Chicken Little:

% go get github.com/chrissnell/chickenlittle

Make a directory for the config file (config.yaml) and the database (chickenlittle.db) to live: sudo mkdir /opt/chickenlittle
Copy the binary you just built into wherever you like to keep third-party software: sudo cp $GOPATH/bin/chickenlittle /usr/local/bin/
Copy the sample config.yaml into the directory you made in step 3: sudo cp $GOPATH/src/github.com/chrissnell/chickenlittle/config.yaml.sample /opt/chickenlittle/config.yaml
Edit the config file and fill in your Twilio and/or Mailgun API keys, endpoint URLs, etc. For the click_url_base and callback_url_base, you can use a service like ngrok for testing or you can run Chicken Little on a public network and put the base URL to your server here.
Start the Chicken Little service: /usr/local/bin/chickenlittle -config PATH_TO_YOUR_CONFIG_YAML
Follow the API instructions to create users and set up notification plans

To Do

Implement on-call rotations for teams of people
Authentication and role-based access control (RBAC) for various API functions.
More test coverage
