Slack extension for the Chaos Toolkit

Chaos Toolkit Extension for Slack

This project is an extension for the Chaos Toolkit to target Slack.

Install

This package requires Python 3.7+

To be used from your experiment, this package must be installed in the Python environment where chaostoolkit already lives.

$ pip install -U chaostoolkit-slack

Slack App

To use this extension, you need to create a Slack app in your workspace. Please follow the Slack documentation to create a basic app:

https://api.slack.com/apps?new_app=1 https://api.slack.com/tutorials

You can start from this manifest if you want:

display_information:
  name: Chaos Toolkit events
  long_description: Get live feedback information of all your Chaos Engineering
    experiments executed from Chaos Toolkit. See which experiments deviated and
    investigate their logs directly from a Slack thread.
  description: Chaos Engineering experiments live events from Chaos Toolkit.
  background_color: "#ffffff"
settings:
  org_deploy_enabled: false
  socket_mode_enabled: false
  is_hosted: false
  token_rotation_enabled: false
features:
  bot_user:
    display_name: chaostoolkit
oauth_config:
  scopes:
    bot:
      - channels:read
      - chat:write
      - files:write

Once your application is created, you may want to set the Chaos Toolkit logo to clarify to your users where these messages come from.

Slack Token

Please follow the procedure on Slack to create a token suitable for API calls made using the Python client. The token should start with xoxb-. You can find the token in your app settings under the OAuth & Permissions page.

The token should have at least the following scopes:

channels:read, chat:write and files:write

Install your Slack app

Once created, you need to install the app in your workspace and invite it in any channel you wish to send events to. This channel will also have to be part specified as a controls argument (see below).

Now you should be good to go!

Usage

Currently, this extension only provides a control to send Chaos Toolkit events to Slack channels.

To use this extension, add the following to your experiment (or settings):

"secrets": {
    "slack": {
        "token": "xoxb-..."
    }
},
"controls": [
    {
        "name": "slack",
        "provider": {
            "type": "python",
            "module": "chaosslack.control",
            "secrets": ["slack"],
            "arguments": {
                "channel": "general"
            }
        }
    }
]
