Overview

The openstacklib module is a part of Stackforge, an effort by the Openstack infrastructure team to provide continuous integration testing and code review for Openstack and Openstack community projects not part of the core software. The module itself is used to expose common functionality between Openstack modules as a library that can be utilized to avoid code duplication.

Module Description

The openstacklib module is a library module for other Openstack modules to utilize. A thorough description will be added later.

This module is tested in combination with other modules needed to build and leverage an entire Openstack software stack. These modules can be found, all pulled together in the openstack module.

Setup

Installing openstacklib

example% puppet module install puppetlabs/openstacklib

Usage

Classes and Defined Types

Defined type: openstacklib::db::mysql

The db::mysql resource is a library resource that can be used by nova, cinder, ceilometer, etc., to create a mysql database with configurable privileges for a user connecting from defined hosts.

Typically this resource will be declared with a notify parameter to configure the sync command to execute when the database resource is changed.

For example, in heat::db::mysql you might declare:

::openstacklib::db::mysql { 'heat':
    password_hash => mysql_password($password),
    dbname        => $dbname,
    user          => $user,
    host          => $host,
    charset       => $charset,
    collate       => $collate,
    allowed_hosts => $allowed_hosts,
    notify        => Exec['heat-dbsync'],
  }

Some modules should ensure that the database is created before the service is set up. For example, in keystone::db::mysql you would have:

::openstacklib::db::mysql { 'keystone':
    password_hash => mysql_password($password),
    dbname        => $dbname,
    user          => $user,
    host          => $host,
    charset       => $charset,
    collate       => $collate,
    allowed_hosts => $allowed_hosts,
    notify        => Exec['keystone-manage db_sync'],
    before        => Service['keystone'],
  }

** Parameters for openstacklib::db::mysql: **

#####password_hash Password hash to use for the database user for this service; string; required

#####dbname The name of the database string; optional; default to the $title of the resource, i.e. 'nova'

#####user The database user to create; string; optional; default to the $title of the resource, i.e. 'nova'

#####host The IP address or hostname of the user in mysql_grant; string; optional; default to '127.0.0.1'

#####charset The charset to use for the database; string; optional; default to 'utf8'

#####collate The collate to use for the database; string; optional; default to 'utf8_unicode_ci'

#####allowed_hosts Additional hosts that are allowed to access this database; array or string; optional; default to undef

#####privileges Privileges given to the database user; string or array of strings; optional; default to 'ALL'

Implementation

openstacklib

openstacklib is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.

Limitations

• Limitations will be added as they are discovered.
