Hello!

Can you please advice the best way - for sending notifications , if role failed on several hosts ?

We have implemented slack notifications about successfully deployed hosts, but how we can get list of failed hosts , and also send notifications ?

Seem’s if host failed, on last step we just not have information about it.

Here is out role:

Hi,

Maybe Slack callback plugin would work better for you?

Enable it by adding slack to the callback_whitelist in /etc/ansible/ansible.cfg
http://docs.ansible.com/ansible/intro_configuration.html#callback-whitelist

Here's documentation from the plugin itself:
https://github.com/ansible/ansible/pull/13408/files
    This is an ansible callback plugin that sends status
    updates to a Slack channel during playbook execution.

    This plugin makes use of the following environment variables:
        SLACK_WEBHOOK_URL (required): Slack Webhook URL
        SLACK_CHANNEL (optional): Slack room to post in. Default: ansible
        SLACK_USERNAME (optional): Username to post as. Default: ansible
        SLACK_INVOCATION (optional): Show command line invocation
                                      details. Default: False

    Requires:
        prettytable

Thanks,

I have tried, but got :

`
[WARNING]: Could not submit message to Slack: HTTP Error 404: Not Found

`

error

Can you please advise, what else can be wrong here?

$ source .slack
$ more .slack
`
SLACK_WEBHOOK_URL=https://hooks.slack.com/services/aaa/bbb/ccc
export SLACK_WEBHOOK_URL

$ grep slack ansible.cfg
callback_whitelist = slack
`

I’ve got the reason of 404 error. Seem’s that

  • SLACK_CHANNEL (optional): Slack room to post in. Default: ansible

is not optional - as we have not special ansible channel in our slack , we use another channel for testing deploys notification.

So callback start sending messages to slack only after specifying another channel via env.

It seem’s strange, because SLACK_WEBHOOK_URL at fact issued to some default channel, but if it’s not ansible - you will get such 404 error.
