Description

A cookbook for 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)

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

Requirements

• The chef_handler cookbook
• An existing Slack incoming webhook(s)

Usage 1

1. Create a new Slack webhook (https://slack.com/services/new/incoming-webhook)
2. Set the team and api_key attributes above on the node/environment/etc.
3. Include this slack_handler recipe.

Usage 1 Attributes

• node['chef_client']['handler']['slack']['team'] - Your Slack team name (<team-name>.slack.com)
• node['chef_client']['handler']['slack']['api_key'] - The API key of your Slack incoming webhook

Optional attributes

• node['chef_client']['handler']['slack']['channel'] - The #channel to send the results
• node['chef_client']['handler']['slack']['username'] - The username of the Slack message
