This commit adds the ::ceilometer::db subclass to the example in README.md. The README.md should contain a working pseudo-minimal example for basic ceilometer installation. At some point the 'db' subclass was required for basic usage. Without this class applying the example in README.md is unusable, erroring out with this: > Error: Could not find dependency Class[Ceilometer::Db] for > Service[ceilometer-api] at > /etc/puppet/modules/ceilometer/manifests/api.pp:112 Change-Id: Ifd0577e23661bc00b98621a622c44c0a9af70a5d

Overview
|
|
--------
|
|
|
|
The ceilometer module is part of [OpenStack](https://github.com/openstack), an effort by the
|
|
OpenStack infrastructure team to provice continuous integration testing and code review for
|
|
OpenStack and OpenStack community projects as part of the core software. The module itself
|
|
is used to flexibly configure and manage the metering service for OpenStack.
|
|
|
|
Module Description
|
|
------------------
|
|
|
|
The ceilometer module is an attempt to make Puppet capable of managing the entirety of ceilometer.
|
|
This includes manifests to provision the ceilometer api, agents, and database stores. A
|
|
ceilometer_config type is supplied to assist in the manipulation of configuration files.
|
|
|

|
### Installing ceilometer
|
|
|
|
puppet module install openstack/ceilometer
|
|
|
|
### Beginning with ceilometer
|
|
|
|
To utilize the ceilometer module's functionality you will need to declare multiple resources. This is not an exhaustive list of all the components needed. We recommend that you consult and understand the [core openstack](http://docs.openstack.org) documentation to assist you in understanding the available deployment options.
|
|
|
|
```puppet
|
|
class { '::ceilometer':
|
|
metering_secret => 'secrete',
|
|
rabbit_userid => 'ceilometer',
|
|
rabbit_password => 'an_even_bigger_secret',
|
|
rabbit_host => '127.0.0.1',
|
|
}
|
|
class { '::ceilometer::client': }
|
|
class { '::ceilometer::collector': }
|
|
class { '::ceilometer::expirer': }
|
|
class { '::ceilometer::alarm::evaluator': }
|
|
class { '::ceilometer::alarm::notifier': }
|
|
class { '::ceilometer::agent::central': }
|
|
class { '::ceilometer::agent::notification': }
|
|
class { '::ceilometer::db': }
|
|
class { '::ceilometer::api':
|
|
enabled => true,
|
|
keystone_password => 'a_big_secret',
|
|
keystone_identity_uri => 'http://127.0.0.1:35357/',
|
|
}
|
|
```
|
|
|
|
Implementation
|
|
--------------
|
|
|
|
### ceilometer
|
|
|
|
ceilometer is a combination of Puppet manifests and Ruby code to deliver configuration and
|
|
extra functionality through types and providers.
|
|
|
|
### Types
|
|
|
|
#### ceilometer_config
|
|
|
|
The `ceilometer_config` provider is a children of the ini_setting provider. It allows one to write an entry in the `/etc/ceilometer/ceilometer.conf` file.
|
|
|
|
```puppet
|
|
ceilometer_config { 'DEFAULT/verbose' :
|
|
value => true,
|
|
}
|
|
```
|
|
|
|
This will write `verbose=true` in the `[DEFAULT]` section.
|
|
|
|
##### name
|
|
|
|
Section/setting name to manage from `ceilometer.conf`
|
|
|
|
##### value
|
|
|
|
The value of the setting to be defined.
|
|
|
|
##### secret
|
|
|
|
Whether to hide the value from Puppet logs. Defaults to `false`.
|
|
|
|
##### ensure_absent_val
|
|
|
|
If value is equal to ensure_absent_val then the resource will behave as if `ensure => absent` was specified. Defaults to `<SERVICE DEFAULT>`
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
* The ceilometer modules have only been tested on RedHat and Ubuntu family systems.
|
|
|
|
Beaker-Rspec
|
|
------------
|
|
|
|
This module has beaker-rspec tests
|
|
|
|
To run:
|
|
|
|
``shell
|
|
bundle install
|
|
bundle exec rspec spec/acceptance
|
|
``
