+IRR - RabbitMQ server
+#####################
+:date: 2015-11-01
+:tags: independent-role-repositories, rabbitmq_server
+
+Split out the rabbitmq_server role into it's own repository.
+
+
+Problem description
+===================
+
+Roles are all contained within a single monolithic repository making it
+impossible/difficult to consume the OSA roles outside of deploying the
+entire stack.
+
+
+Proposed change
+===============
+
+To ensure that the OSA project is consumable by other stacks using different
+architectures, deployment methods, and capabilities the role
+"rabbitmq_server" need to be moved from the monolithic stack and
+into the it's own role repository.
+
+
+Alternatives
+------------
+
+Leave everything the way it is. However doing that will hurt general OSA
+adoption.
+
+
+Playbook/Role impact
+--------------------
+
+* No impact to the playbooks.
+* The role will be removed from the main stack. The plugins, filters, and
+  libraries may need to be locally updated.
+
+
+Upgrade impact
+--------------
+
+While the change will impact the placement of the role it will not impact
+upgrade-ability of the stack. The general workflow will need to be updated
+to ensure that users are updating roles on upgrade  using the Ansible
+galaxy interface however generally speaking this is already being done for
+the deployer when running the ``bootstrap-ansible.sh`` script.
+
+
+Security impact
+---------------
+
+n/a
+
+
+Performance impact
+------------------
+
+Moving the role to an external repository will cause an impact in time  to
+role resolution however that impact should be minimal.
+
+
+End user impact
+---------------
+
+n/a
+
+
+Deployer impact
+---------------
+
+Deployers will need to be aware of the new role locations and how to update
+existing roles however this should be minimal considering the tooling for
+updating existing roles already exists
+
+
+Developer impact
+----------------
+
+Developers will need focus work within the roles which will exist within
+separate repositories.

+
+
+Work items
+----------
+
+* With the role moved, tests will be created within the role via OpenStack CI
+  to ensure that the role is performing the actions that its supposed to.
+* Updated documentation via the "README.rst" will be created to show how the
+  role can be used standalone.
+* Example local inventory will be created to show how the role can be used.
+  The local only inventory will also be used for testing the role.
+
+
+Testing
+=======
+
+* The test cases will deploy the role into a regular DSVM image
+* The role will execute itself locally
+* Once the role has completed an Ansible test play will run through several
+  assert tasks to ensure the role functioned as intended.
+
+
+Documentation impact
+====================
+
+The base README.rst file will be updated to explain how the role can be used
+as a standalone role.
