Developing a vars_plugin

[Guy Matz]

Hi!  Anyone have any advice on developing a vars_plugin?  This may sound kinda screwy, but for a chef -> ansible transition I need to access data from a chef data_bag in an ansible play . . .  I'm able to get the chef data using pychef, but I'm having issues when trying to run the code within vars_plugin code:

import chef

def get_dbag_data():

    chef_api = chef.autoconfigure()

    dbag, dbag_item = 'dbag', 'dbag_item'

    bag = chef.DataBag(dbag)  # some debugging shows the problem is here on the second run. . !

    item = bag[dbag_item]

    return item.to_dict()

The code above works outside of ansible, but when run in ansible it seems to get run twice, and fails on the "bag = chef.DataBag(dbag)" line the second time around.

Any thoughts would be greatly appreciated!

Thanks!

Perhaps you could show your vars_plugin?  There is the potential that it could be run twice, depending on where you call that code from.

The 3 following methods are all run 1 time in ansible.inventory.Inventory:

plugin.get_group_vars

plugin.run

plugin.get_host_vars

Also, as a heads up, this is probably a better discussion for ansible-devel.
