apt__keys - reading from ansible controller

Good day, I have a need where the destination instances only have access to a apt_cacher_ng to fetch data. I would like to make use of something like the debops.keyring role to push the locally (on the Ansible controller) stored .asc files (typically all those that would’ve been in {{inventory}}/../keyring/ ) to the instances. Is it doable in the inventory to be pushed using the bootstrap playbook, or do I need to do some other hackery first? Hendrik
