Hi @sivel I am trying to get an Slack callback plugin to work ([https://github.com/sivel/ansible/blob/slack-callback/plugins/callbacks/slack.py#L142-L147](https://github.com/sivel/ansible/blob/slack-callback/plugins/callbacks/slack.py#L142-L147)), but I am getting the following error:# Unexpected Exception: ‘module’ object has no attribute ‘warning’ You can see the what I am trying to achieve here: [https://github.com/ansible/ansible/pull/8955](https://github.com/ansible/ansible/pull/8955) When looking at the file I see that it mentions the following: class CallbackModule(object): “”"This is an example ansible callback plugin that sends status updates to a Slack channel during playbook execution. This plugin makes use of the following environment variables: SLACK\_TOKEN (required): Slack Integration token SLACK\_TEAM (required): Slack team name [TEAM.slack.com](http://TEAM.slack.com) SLACK\_CHANNEL (optional): Slack room to post in. Default: #ansible SLACK\_USERNAME (optional): Username to post as. Default: ansible Requires: prettytable “”" Where would I need to insert these SLACK environment variables in order for this file to access this information? ---

Those environment variables need to be set in the shell that you execute Ansible from. Also that branch/PR that you reference is for Ansible 1.9. If you need a version that works with Ansible 2.0, see [https://github.com/ansible/ansible/pull/13408](https://github.com/ansible/ansible/pull/13408) ---

Hi Matt I have now updated the slack.py with the following code ([https://github.com/sivel/ansible/blob/v2-slack-callback/lib/ansible/plugins/callback/slack.py](https://github.com/sivel/ansible/blob/v2-slack-callback/lib/ansible/plugins/callback/slack.py)), as I am running Ansible v2. I have added the environmental variables into a ver basic playbook to see if it posts the results to Slack (see below): ---

In Ansible v2 you must whitelist callback plugins in ansible.cfg. Additionally, the environment vars must be set in your shell, not in the playbook. In bash this would be done from a .bash\_profile or directly on the command line by using: export SLACK\_TOKEN=mytoken ---

Hi Matt Thanks for your quick responses. I have now added SLACK\_WEBHOOK\_URL and SLACK\_CHANNEL to the environment var in the shell SLACK\_TOKEN=[https://hooks.slack.com/services/xxxxxx/yyyyyyyy/token](https://hooks.slack.com/services/xxxxxx/yyyyyyyy/token) SLACK\_CHANNEL=#ansible I have also added the withlist entry into ansible.cfg: # set plugin path directories here, separate with colons action\_plugins = /usr/share/ansible\_plugins/action\_plugins callback\_plugins = /usr/share/ansible\_plugins/callback\_plugins connection\_plugins = /usr/share/ansible\_plugins/connection\_plugins lookup\_plugins = /usr/share/ansible\_plugins/lookup\_plugins vars\_plugins = /usr/share/ansible\_plugins/vars\_plugins filter\_plugins = /usr/share/ansible\_plugins/filter\_plugins callback\_whitelist = slack.py I then try run the playbook: ---

I think the whitelist is just slack without the file extension. Also, if you run Ansible with higher verbosity, it will show you which callbacks are being loaded. ---

you should not need to whitelist custom plugins, that was done only for the plugins shipped with ansible (which have a variable that indicates they NEED the whitelist to work). ---

Hi guys This is working perfectly running playbooks from the server. But when I run any playbooks from Ansible Tower nothing is being send to Slack. Is there something that you know that needs to be done in order for this to work? Cheers Mark
