Overview

The sysinv 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 its self is used to flexibly configure and manage the block storage service for Openstack.

Module Description

The sysinv module is a thorough attempt to make Puppet capable of managing the entirety of sysinv. This includes manifests to provision such things as keystone endpoints, RPC configurations specific to sysinv, and database connections. Types are shipped as part of the sysinv 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 sysinv module affects

• sysinv, the block storage service for Openstack.

Installing sysinv

example% puppet module install puppetlabs/sysinv

Beginning with sysinv

To utilize the sysinv 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 sysinv control node

class { '::sysinv':
  sql_connection      => 'mysql://sysinv:secret_block_password@openstack-controller.example.com/sysinv',
  rabbit_password     => 'secret_rpc_password_for_blocks',,
  rabbit_host         => 'openstack-controller.example.com',
  verbose             => true,
}

class { '::sysinv::api':
  keystone_password       => $keystone_password,
  keystone_enabled        => $keystone_enabled,
  keystone_user           => $keystone_user,
  keystone_auth_host      => $keystone_auth_host,
  keystone_auth_port      => $keystone_auth_port,
  keystone_auth_protocol  => $keystone_auth_protocol,
  service_port            => $keystone_service_port,
  package_ensure          => $sysinv_api_package_ensure,
  bind_host               => $sysinv_bind_host,
  enabled                 => $sysinv_api_enabled,
}

class { '::sysinv::scheduler': scheduler_driver => 'sysinv.scheduler.simple.SimpleScheduler', }

Define a sysinv storage node

class { '::sysinv':
  sql_connection      => 'mysql://sysinv:secret_block_password@openstack-controller.example.com/sysinv',
  rabbit_password     => 'secret_rpc_password_for_blocks',,
  rabbit_host         => 'openstack-controller.example.com',
  verbose             => true,
}

class { '::sysinv::volume': }

class { '::sysinv::volume::iscsi': iscsi_ip_address => '10.0.0.2', }

Implementation

sysinv

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

Limitations

• Setup of storage nodes is limited to Linux and LVM, i.e. Puppet won't configure a Nexenta appliacne but nova can be configured to use the Nexenta driver with Class['sysinv::volume::nexenta'].

Development
