parameters to serial cannot depend on inventory as it gets read AFTER
the play is evaluated (serial value is assigned). So use extra vars to
set serial dynamically.

[ansible-project] Variables and serial: keyword

2015-12-11 Thread Eugene Zhulkov 
I've been struggling with passing variable to serial for the whole day.

All I need is to pass group's length, I've tried 
serial: "{{ groups['appserver']|length }}"

and got a runtime error.

Finally I come up with this code: 
serial: "{{ lookup('group_size', 'appserver') }}"

, where *group_size* is a custom lookup plugin. 

Now I have another problem - how can I get access to inventory instance 
inside lookup plugin? I don't understand API design - all plugins have 
"runner" instance in constructor except LookupModule. 

So my questions are:
- can I parameterize serial?
- can I access inventory inside LookupModule?

Thank you!
