OpenStack Ansible Modules
=========================
The OpenStack collection (on `Galaxy <https://galaxy.ansible.com/openstack/cloud>`_, source code `repository <https://opendev.org/openstack/ansible-collections-openstack.git>`_) contains modules for interacting with OpenStack as either an admin or an end user. If the module does not begin with ``os_``, it is either deprecated or soon to be deprecated. This document serves as developer coding guidelines for modules in this collection.
.. contents::
:local:
Naming
------
* All module names should start with ``os_``
* Name any module that a cloud consumer would expect to use after the logical resource it manages: ``os_server`` not ``os_nova``. This naming convention acknowledges that the end user does not care which service manages the resource - that is a deployment detail. For example cloud consumers may not know whether their floating IPs are managed by Nova or Neutron.
* Name any module that a cloud admin would expect to use with the service and the resource: ``os_keystone_domain``.
* If the module is one that a cloud admin and a cloud consumer could both use,
the cloud consumer rules apply.
Interface
---------
* If the resource being managed has an id, it should be returned.
* If the resource being managed has an associated object more complex than
an id, it should also be returned.
Interoperability
----------------
* It should be assumed that the cloud consumer does not know a bazillion
details about the deployment choices their cloud provider made, and a best
effort should be made to present one sane interface to the Ansible user
regardless of deployer insanity.
* All modules should work appropriately against all existing known public
OpenStack clouds.
* It should be assumed that a user may have more than one cloud account that
they wish to combine as part of a single Ansible-managed infrastructure.
Libraries
---------
* All modules should use ``openstack_full_argument_spec`` to pick up the
standard input such as auth and ssl support.
* All modules should include ``extends_documentation_fragment: openstack``.
* All complex cloud interaction or interoperability code should be housed in
the `openstacksdk <https://git.openstack.org/cgit/openstack/openstacksdk>`_
library.
* All OpenStack API interactions should happen via the openstacksdk and not via
OpenStack Client libraries. The OpenStack Client libraries do no have end
users as a primary audience, they are for intra-server communication.
Testing
-------
* Integration testing is currently done in `OpenStack's CI system <https://git.openstack.org/cgit/openstack/openstacksdk/tree/openstack/tests/ansible>`_
* Testing in openstacksdk produces an obvious chicken-and-egg scenario. Work is under
way to trigger from and report on PRs directly.
