OpenStack Glance Puppet Module

Emilien Macchi f55cebf7b6 Try to use zuul-cloner to prepare fixtures
In OpenStack Infra, we would like to run Puppet unit tests that
sometimes depends on other Puppet OpenStack modules.
Example: a patch in puppet-openstacklib that needs to be tested in puppet-nova.

This patch modifies the Rakefile to:
* clean spec_prep and spec_clean Rake tasks
* use openstack/puppet-openstack-integration/install_modules_unit.sh script
  to clone modules.
* do not use .fixtures.yaml file to clone modules and rely on
  zuul-cloner or git.
* Add openstack/ in gitignore so we never commit the
  puppet-openstack-integration repository (can happen when spec_clean
  did not run but you want to submit the patch anyway)
* Allow to run a custom Puppetfile if PUPPETFILE env is exported. It
  will allow people to test the module with the dependencies they like,
  feature we had with .fixtures.yaml.

Also add 'r10k' to Gemfile.

That way, we will be able to use zuul dependencies and run tests accross
modules like we do with functional testing.

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
