charm-aodh/src

Overview

This charm provides the Aodh Alarming service for an OpenStack Cloud.

Usage

Aodh relies on services from the mongodb, rabbitmq-server and keystone charms:

juju deploy aodh
juju deploy keystone
juju deploy mysql
juju deploy rabbitmq-server
juju add-relation aodh rabbitmq-server
juju add-relation aodh mysql
juju add-relation aodh keystone

Policy Overrides

Policy overrides is an advanced feature that allows an operator to override the default policy of an OpenStack service. The policies that the service supports, the defaults it implements in its code, and the defaults that a charm may include should all be clearly understood before proceeding.

Caution: It is possible to break the system (for tenants and other services) if policies are incorrectly applied to the service.

Policy statements are placed in a YAML file. This file (or files) is then (ZIP) compressed into a single file and used as an application resource. The override is then enabled via a Boolean charm option.

Here are the essential commands (filenames are arbitrary):

zip overrides.zip override-file.yaml
juju attach-resource aodh policyd-override=overrides.zip
juju config aodh use-policyd-override=true

See appendix Policy Overrides in the OpenStack Charms Deployment Guide for a thorough treatment of this feature.
