Slack Callback Plugin Usage

[andrew...@xtra.co.nz]

I'm trying to use the Slack callback plugin (https://docs.ansible.com/ansible/devel/plugins/callback/slack.html) in the hopes that it will send notifications as a playbook is executed and when it completes successfully or otherwise.

Unfortunately the documentation is poor bordering on non-existant.  What I have been able to glean is:

1. Install prettytable python library
2. Update ansible.cfg with "callback_whitelist = slack"

From there it all gets a bit murky.  I should be able to setup some ini entries - no idea where so I took a wild guess and added this to ansible.cfg

[callback_slack]
webhook_url = https://hooks.slack.com/services/<my>/<slack>/<token>
channel = #preprod

Which gives this error when running a playbook:

ERROR! Unexpected Exception, this is probably a bug: 'webook_url'
the full traceback was:

Traceback (most recent call last):
  File "/usr/bin/ansible-playbook", line 106, in <module>
    exit_code = cli.run()
  File "/usr/lib/python2.7/site-packages/ansible/cli/playbook.py", line 130, in run
    results = pbex.run()
  File "/usr/lib/python2.7/site-packages/ansible/executor/playbook_executor.py", line 90, in run
    self._tqm.load_callbacks()
  File "/usr/lib/python2.7/site-packages/ansible/executor/task_queue_manager.py", line 202, in load_callbacks
    callback_obj = callback_plugin()
  File "/usr/lib/python2.7/site-packages/ansible/plugins/callback/slack.py", line 93, in __init__
    self.webhook_url = self._plugin_options['webook_url']
KeyError: 'webook_url'

Apart from getting this to work my other requirement that I'm not sure how to meet is how to I set the channel to match the name of the inventory I'm deploying to? Ideally I'd set the ini setting to something like "{{ inventory_dir|basename }}" but not sure if it would support that.  Otherwise I need to set "env:SLACK_CHANNEL" which I don't know how to do in Ansible.

NOTE: My playbooks are targeting windows hosts.

 

Versions:

ansible-playbook 2.4.0.0
python version = 2.7.5 (default, Aug  2 2016, 04:20:16) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]

Thanks

That error has been fixed as of 2.4.1.  Please try upgrading and test again.  2.4.2 is the current stable release.

After upgrading, I believe everything should work as you have configured it.
