Overview
--------
The neutron module is a part of [OpenStack](https://opendev.org/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 itself is used to flexibly configure and manage the network service for OpenStack.
Module Description
------------------
The neutron module is an attempt to make Puppet capable of managing the entirety of neutron. This includes manifests to provision such things as keystone endpoints, RPC configurations specific to neutron, database connections, and network driver plugins. Types are shipped as part of the neutron module to assist in manipulation of the OpenStack configuration files.
This module is tested in combination with other modules needed to build and leverage an entire OpenStack installation.
Setup
-----
**What the neutron module affects:**
* [Neutron](https://docs.openstack.org/neutron/latest/), the network service for OpenStack.
### Installing neutron
puppet module install openstack/neutron
### Beginning with neutron
To utilize the neutron module's functionality you will need to declare multiple resources. The following example displays the setting up of an Open vSwitch neutron installation. This is not an exhaustive list of all the components needed. We recommend that you consult and understand the [core openstack](https://docs.openstack.org) documentation to assist you in understanding the available deployment options.
```puppet
class { 'neutron':
bind_host => '127.0.0.1',
default_transport_url => 'rabbit://neutron:passw0rd@localhost:5672/neutron',
debug => false,
}
class { 'neutron::db':
database_connection => 'mysql+pymysql://neutron:neutron_sql_secret@127.0.0.1/neutron?charset=utf8',
}
class { 'neutron::server':
}
class { 'neutron::keystone::authtoken':
password => 'keystone_neutron_secret',
}
# ml2 plugin with vxlan as ml2 driver and ovs as mechanism driver
class { 'neutron::plugins::ml2':
type_drivers => ['vxlan'],
tenant_network_types => ['vxlan'],
vxlan_group => '239.1.1.1',
mechanism_drivers => ['openvswitch'],
vni_ranges => ['1:300']
}
```
Other neutron network drivers include:
* dhcp,
* metadata,
* and l3.
The `examples` directory also provides a quick tutorial on how to use this module.
Implementation
--------------
### neutron
neutron is a combination of Puppet manifest and ruby code to deliver configuration and extra functionality through *types* and *providers*.
### Types
#### neutron_config
The `neutron_config` provider is a children of the ini_setting provider. It allows one to write an entry in the `/etc/neutron/neutron.conf` file.
```puppet
neutron_config { 'DEFAULT/core_plugin' :
value => ml2,
}
```
This will write `core_plugin=ml2` in the `[DEFAULT]` section.
##### name
Section/setting name to manage from `neutron.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
-----------
This module supports only the ml2 plugin, and its mechanism drivers listed below.
* Arista
* Baremetal
* L2 Population
* Macvtap
* Open vSwitch
* OVN
* SR-IOV
Development
-----------
The puppet-openstack modules follow the OpenStack development model. Developer documentation for the entire puppet-openstack project is at:
* https://docs.openstack.org/puppet-openstack-guide/latest/
