oncall-buddy-finder

OBF is a tool that help to integrate your monitoring system with a google calendar to manage the oncall shedule within a team.

It will fetch the oncall schedule defined in a google calendar and keep a contact file, based on a template, in sync with the schedule. The contact file is then sourced our notifications system.

The idea is to have this programm running as a service to have always the good contact notified by the monitoring system.

Templating

The template is totally customizable (handled by golang text/templates)

Notifications

It also include some notifications capabilities using a slack webhook to inform who is oncall today.

Requirements

You will need the following:

• a Google Api Service Account Key (from https://console.developers.google.com)
• a config file
• a pre-configured slack webhook (if you want to use notifications)

Install

Configuration

Configuration is handled as 3 levels (in the order of precedence):

* JSON config file

The program will try to guess the best config file for you:
