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)

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

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.

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
  • node['chef_client']['handler']['slack']['channel'] - The #channel to send the results, should include the hash

Optional attributes

  • node['chef_client']['handler']['slack']['username'] - The username of the Slack message, defaults to the node name

# Add `webhook1` URL

Changelog

0.7.0

  • Added send_start_message configuration which if set to true sends out a message when this cookbook is run. This is not quite the same as a Chef start handler but requires no additional setup to run. If you have other start handlers registered, they may run twice due if you turn this setting on. Default setting is false.
  • Added send_environment configuration which if set to true sends the node.chef_environment. Default setting is false.

v0.6.0

  • Fix a bug in run_context where we should be calling Chef.run_context, correct an incorrect method name. (#22)

v0.5.0

  • Added cookbook_detail_level configuration which provides the optional ability to include a list of all cookbooks used in the message to Slack. Values inside README.md (#17)
  • Some defaults have been removed from the WebHook integration to allow Slack WebHook default configuration to be used, can still be overridden (#16). The slackr integration remains the same. Specifically:
    • username no longer defaults to node.name
    • username no longer defaults to chef_handler
    • icon_emoji no longer defaults to :fork_and_knife:
  • Changed detail_level to message_detail_level in order to clarify its meaning against cookbook_detail_level
  • Optional fail_only, message_detail_level and cookbook_detail_level attributes for WebHook can now drop down to global attributes (#18)
