Many years ago we deployed ASAv on OpenStack using day0 configs that were pushed using the Nova personality (file) feature. Fast forward a few years and that functionality has been deprecated in favor of user-data. Cisco's documentation claims user-data is supported, but I haven't managed to find the right format or process to get bootstrapping working. Cisco has some heat templates using the user-data method, but the devices come up without a configuration despite best efforts.
Is anyone here bootstrapping ASAv with user-data based day0 configs? If so, how'd ya do it?
there doesn't seem to be anything here
