How to get the ansible command line information like current tags, skip-tags, limit, etc?

I am integrating some automated slack messaging in ansible to inform on ansible runs and it would be useful to display information such as:

Current tags in push
Current skip-tags in push
Current limit (though I know i can use play_hosts for listing the servers)

To be honest, the whole ansible command would be helpful. I am doing this with a local action shell now:

shell ps aux | grep ‘ansible-playbook’ | grep -v grep

…but besides it being very janky, this is unpredictable if there are multiple ansible-playbooks running on one host, like in my jenkins server.

I scanned all the built in vars that I know of for some of this information but no luck.

Thanks!

Jordan,

Have you looked at the slack callback plugin that is already bundled with ansible?

In your ansible.cfg you would need to have something like:

[defaults]
callback_whitelist = slack

The docstring for the callback has information about what environment variables need to be set up for it to work:

https://github.com/ansible/ansible/blob/devel/lib/ansible/plugins/callback/slack.py#L43-L56

To get it to display things like tags, skip tags, limit, etc…you will need to set SLACK_INVOCATION=True

The callback plugin is really nice, i didn’t know it existed.

For my purposes though, I would like to use the slack module so that I can more custom tailor the message, the channel to post to, and when to skip a slack message (for local/dev environments)

But thank you, this is cool.

So I guess to answer your question directly, there is no way to access tags, skip tags, limit and most other command line options from within a play.

It’s really only achievable via a callback.

Hello!

I have the same issue with necessity of tags, limits, etc using slack as callback , and found strange thing:

If i set SLACK_INVOCATION=True , nothing happens.

Actually, in ansible/plugins/callback/slack.py where is another dependency:

`
def v2_playbook_on_start(self, playbook):

self.playbook_name = os.path.basename(playbook._file_name)

title = [
‘Playbook initiated (%s)’ % self.guid
]
invocation_items =
------>> if self._options and self.show_invocation:
tags = self._options.tags
skip_tags = self._options.skip_tags
extra_vars = self._options.extra_vars
subset = self._options.subset

`

And by default seem’s self._options set to none:

How I can properly set “self._options” to get all necessary details?

Now I found only one way , by hacking ansible/plugins/callback/slack.py with

`

def v2_playbook_on_start(self, playbook):

self.playbook_name = os.path.basename(playbook._file_name)

title = [
‘Playbook initiated (%s)’ % self.guid
]
invocation_items =
------>> self._options = cli.options

if self._options and self.show_invocation:
tags = self._options.tags
skip_tags = self._options.skip_tags
extra_vars = self._options.extra_vars
subset = self._options.subset

`

But I am sure, must been some other , better way here :wink:
Can anyone advise ?

Thanks in advance!

ps:
`
$ ansible --version
ansible 2.2.1.0
$ set | grep INV
SLACK_INVOCATION=True

`
