+======================================
+Add support for multiple globals files
+======================================
+
+https://blueprints.launchpad.net/kolla-ansible/+spec/multiple-globals-files
+
+Adding this feature to the kolla-ansible script, which will make it, automatically,
+read multiple globals files. This would give operators the ability to have
+separate globals files for some services, giving them a bit more granular control,
+without the need to add the ``-e @/path/to/file`` flag. These files will be placed
+under a new ``/etc/kolla/globals.d`` directory and ``kolla-ansible`` will search
+for ``globals.d/*.yml`` files. The main ``globals.yml`` file will still exist
+under ``/etc/kolla``, as usual.
+
+Problem description
+===================
+
+There's no problem, per say, to solve. This feature will basically give operators
+the ability to have separate globals files for some services, giving them a bit
+more granular control, without the need to add the ``-e @/path/to/file`` flag.
+
+Use cases
+---------
+1. Allow a more granular controler over individual service's options
+2. Better file and directory structure
+
+Proposed change
+===============
+
+- Add the capability in the ``tools/kolla-ansible`` script
+  - Check if the ``globals.d`` directory exists
+  - If it is, add its files in the ``CONFIG_OPTS`` variable at the end of the ``tools/kolla-ansible`` script
+
+Security impact
+---------------
+
+None
+
+Performance Impact
+------------------
+
+None
+
+
+Implementation
+==============

+
+Milestones
+----------
+
+Target Milestone for completion:
+  ussuri-10.0.0
+
+Work Items
+----------
+
+- Add the capability in the ``tools/kolla-ansible`` script
+  - Check if the ``globals.d`` directory exists
+  - If it is, add its files in the ``CONFIG_OPTS`` variable at the end of the ``tools/kolla-ansible`` script
+
+Testing
+=======
+Test the new kolla-ansible script when the ``globals.d`` directory exists and
+includes some more yml files, as well as when it doesn't exist.
+
+Documentation Impact
+====================
+``doc/source/user/quickstart.rst`` will need to be updated to include the options discussed in this feature
