Description

A cookbook for configures a Chef handler that sends reports and exceptions to Slack. There are two options for use:

  1. Providing a team name and api_key (Uses the slackr gem)
  2. Providing a hash containing incoming webhook url(s)

NOTE: If both methods are configured, webhooks will take precedence.

  • v1.0.0 of this cookbook requires chef-client 14+, users of older chef clients should pin to previous version ~>0.9.2

This cookbook was originally a fork of dcm-ops/chef-slack_handler by Dan Ryan. We have taken over maintenance of this cookbook and released it to Supermarket.
