Overview
The glance module is a part of OpenStack, an effort by the OpenStack infrastructure team to provide continuous integration testing and code review for OpenStack and OpenStack community projects as part of the core software. The module its self is used to flexibly configure and manage the image service for OpenStack.
Module Description
The glance module is a thorough attempt to make Puppet capable of managing the entirety of glance. This includes manifests to provision such things as keystone endpoints, RPC configurations specific to glance, and database connections. Types are shipped as part of the glance module to assist in manipulation of configuration files.
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
What the glance module affects
- Glance, the image service for OpenStack.
Installing glance
puppet module install openstack/glance
Beginning with glance
To utilize the glance module's functionality you will need to declare multiple resources. The following is a modified excerpt from the openstack module. This is not an exhaustive list of all the components needed, we recommend you consult and understand the openstack module and the core openstack documentation.
Define a glance node
class { 'glance::api':
verbose => true,
keystone_tenant => 'services',
keystone_user => 'glance',
keystone_password => '12345',
database_connection => 'mysql://glance:12345@127.0.0.1/glance',
}
class { 'glance::registry':
verbose => true,
keystone_tenant => 'services',
keystone_user => 'glance',
keystone_password => '12345',
database_connection => 'mysql://glance:12345@127.0.0.1/glance',
}
class { 'glance::backend::file': }
Setup postgres node glance
class { 'glance::db::postgresql':
password => '12345',
}
Setup mysql node for glance
class { 'glance::db::mysql':
password => '12345',
allowed_hosts => '%',
}
Setup up keystone endpoints for glance on keystone node
class { 'glance::keystone::auth':
password => '12345'
email => 'glance@example.com',
public_address => '172.17.0.3',
admin_address => '172.17.0.3',
internal_address => '172.17.1.3',
region => 'example-west-1',
}
Setup up notifications for multiple RabbitMQ nodes
class { 'glance::notify::rabbitmq':
rabbit_password => 'pass',
rabbit_userid => 'guest',
rabbit_hosts => [
'localhost:5672', 'remotehost:5672'
],
rabbit_use_ssl => false,
}
Types
glance_api_config
The glance_api_config
provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/glance/glance-api.conf
file.
glance_api_config { 'DEFAULT/verbose' :
value => true,
}
This will write verbose=true
in the [DEFAULT]
section.
name
Section/setting name to manage from glance-api.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>
glance_registry_config
The glance_registry_config
provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/glance/glance-registry.conf
file.
glance_registry_config { 'DEFAULT/verbose' :
value => true,
}
This will write verbose=true
in the [DEFAULT]
section.
name
Section/setting name to manage from glance-registry.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>
glance_cache_config
The glance_cache_config
provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/glance/glance-cache.conf
file.
glance_cache_config { 'DEFAULT/verbose' :
value => true,
}
This will write verbose=true
in the [DEFAULT]
section.
name
Section/setting name to manage from glance-cache.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>
Implementation
glance
glance is a combination of Puppet manifest and ruby code to deliver configuration and extra functionality through types and providers.
Limitations
- Only supports configuring the file, swift and rbd storage backends.
Beaker-Rspec
This module has beaker-rspec tests
To run the tests on the default vagrant node:
To run:
bundle install
bundle exec rspec spec/acceptance
