Trove Charm Support
=====================
To add a service to Openstack to provide on-demand databases.
Problem Description
===================
As a cloud user I need be able to deploy a database that is scalable and
reliable quickly and easily without the burden of handling complex
administrative tasks.
Proposed Change
===============
Trove will need to undergo MIR review for main inclusion; this process
should include stripping of all debconf/dbconfig related code from the
packaging.
One new charm - Trove with corresponding tests and QA CI/setup.
The new Trove charm should include, as a minimum, the following features:
- Deployable in a highly available configuration
- Allow clients and services to interact using SSL encryption
- Charm progress displayed via workload status
Alternatives
------------
Juju delpoy {mysql,percona-cluster,cassandra,etc}
Implementation
==============

Work Items
----------
Provide fully supported packages for Ubuntu
===========================================
- Package updates for Trove to strip all debconf/dbconfig related code from
the packaging.
- MIR review for Trove - Evaluate package and source according to
https://wiki.ubuntu.com/MainInclusionProcess, open corresponding bug, work
with Ubuntu MIR team and make any other necessary package changes to get
package into main.
Provide Trove charm
========================
- Create skeleton charm layer based on OpenStack base layer and available
interface layers to deploy Trove.
- Add support for upgrading Trove
- Add config option and accompanying support for upgrades via
action-managed-upgrade.
- Add support for deploying Trove in a highly available configuration
- Add support for the Trove to display workload status
- Add support SSL endpoints
- Charm should have unit and functional tests.
Mojo specification deploying and testing Trove
================================================
- Write Mojo spec for deploying Trove in an HA configuration and testing
creation of databases.
Repositories
------------
git@github.com:openstack-charmers/charm-trove.git
Documentation
-------------
The Trove charm should contain a README with instructions on deploying the
charm. A blog post is optional but would be a useful addition.
Security
--------
No additional security concerns.
Testing
-------
Code changes will be covered by unit tests; functional testing will be done
using a combination of Amulet, Bundle tester and Mojo specification.
