Fuel configuration files reference
==================================
You can modify some of the Fuel settings directly in the corresponding
configuration files.
.. warning:: For advanced OpenStack users only!
Editing the Fuel configuration files
may severely damage your OpenStack environment.
After you modify a ``yaml`` file, you will get an notification in
the Fuel web UI that some settings have been changed and, therefore,
some features may become inaccessible in the Fuel web UI.
The following table provides descriptions of the Fuel configuration files.
+-------------------------------+-------------+------------------------------+

Fuel Slave nodes:
**/etc/astute.yaml**
Fuel uses the *astute.yaml* file to pass configuration attributes
to Puppet.
Usage
+++++
The */etc/astute.yaml* file is placed
on each Fuel Slave node when it is deployed
by **mcollective** and must not be deleted.
The Facter extension reads data from this file
and uses it to create the `$::fuel_settings` data structure.
This structure contains all variables as a single hash
and supports embedding of other rich structures
such as nodes hash or arrays.

MongoDB nodes configuration
+++++++++++++++++++++++++++
Each OpenStack environment that uses Ceilometer
and MongoDB must have a definition for each MongoDB node
in the *astute.yaml* file. One node is designated as
the `primary-mongo` node and all other nodes have
`mongo` specified as a role.
Ideally, you should have one MongoDB node for each
controller node in an OpenStack environment.
You can use the Fuel web UI to deploy
as many MongoDB nodes as required
when you initially create your OpenStack environment.
You must edit this file and use command line
to add MongoDB nodes to the deployed OpenStack environment.
The configuration for the primary MongoDB node is:
::
- role: primary-mongo
internal_netmask: 255.255.255.0
storage_netmask: 255.255.255.0
internal_address: 10.108.22.6
uid: "12"
swift_zone: "12"
name: node-12
storage_address: 10.108.24.5
fqdn: node-12.test.domain.local
The fields are:
:internal_netmask: Netmask used for the Internal.
:storage_netmask: Netmask used for the Storage logical network.
:internal_address:
:uid:
:swift_zone:
:name:
:storage_address:
:fqdn:
The configuration for each non-primary MongoDB node:
has the same fields.
The *astute.yaml* file includes one section like this
for each configured MongoDB node:
::
- role: mongo
internal_netmask: 255.255.255.0
storage_netmask: 255.255.255.0
internal_address: 10.108.22.7
uid: "13"

name: node-13
storage_address: 10.108.24.6

If you make a mistake when populating this file,
it seems to upload normally
but no network data changes are applied;
if you then download the file again,
the unmodified file may overwrite
the modifications you made to the file.
To protect yourself,
we recommend the following process:
- After you edit the file but before you upload it,
make a copy in another location.
- Upload the file.
- Download the file again.
- Compare the current file to the one you saved.
If they match, you successfully configured your networks.
If you configure your networking by editing this file,
you should create and configure the rest of your environment
using the Fuel CLI rather than the Web UI.
Especially do not attempt to configure your networking
using the Web UI screens.
File Format
+++++++++++
The *network_1.yaml* file contains
**global settings** and the **networks** section.
Note that the *network_1.yaml* is dumped in dictionary order
so the sections may appear in a different order than
documented here.
Global settings
+++++++++++++++
are mostly at the beginning of the file
but one (**public_vip**) is at the end of the file,
When configuring a new environment,
you must set values for the **management_vip**,
**floating_ranges**, and **public_vip** parameters.

Networks
++++++++
The **networks** section contains the configurations
of each Network Group that has been created.
You must set values for
the **cidr**, **gateway**, and **ip_ranges** parameters
for each logical network in the group.
This is what the configuration of one logical network (**public**)looks like.
A similar section is provided for each of the
logical networks that belong to the Node Group.

If you create additional Node Groups,
the file contains segments for each Node Group,
each identified by a unique **group_id**,
with configuration blocks for each
of the four logical networks associated with that Node Group.

openstack.yaml
--------------
Fuel Master Node:
**/usr/lib/python2.6/site-packages/nailgun/fixtures/openstack.yaml**
The *openstack.yaml* file defines
the basic configuration of the target nodes
that Fuel deploys for the OpenStack environment.
Initially, it contains Fuel defaults;
these are adjusted in response to configuration choices
the user makes through the Fuel UI
and then fed to Nailgun.
Usage
+++++
#. Log into the nailgun Docker container:
::
dockerctl shell nailgun
#. Edit file.
#. Run the following commands to Nailgun
to reread its settings and restart:
::
manage.py dropdb && manage.py syncdb && manage.py loaddefault
killall nailgund
#. Exit the Nailgun docker container:
::
exit
#. Run the following commands to Nailgun
to sync deployment tasks:
::
fuel rel --sync-deployment-tasks --dir /etc/puppet
File Format
+++++++++++
The *openstack.yaml* file contains a number of blocks,
each of which may contain multiple parameters.
The major ones are described here.
The file has two major sections:
- The first is for VirtualBox and other limited deployments.
- The second is for full bare-metal deployments.
Roles
+++++
Lists each of the roles available on the
:guilabel:`Assign Roles` screen
with descriptions.
Note that there are two `roles-metadata` sections in the file:
- The limited deployments section
lists only the Controller, Compute, and Cinder LVM roles.
- The "full_release" section
lists the Controller, Compute, Cinder LVM,
Ceph-OSD, MongoDB, and Zabbix Server roles.
Roles that should not be deployed on the same server
are identified with "conflicts" statements
such as the following that prevents a Compute role
from being installed on a Controller node:
::
controller:
name: "Controller"
description: "The controller initiates orchestration activities..."
has_primary: true
conflicts:
- compute
The "has_primary" line is added in Release 6.0
to identify the Primary controller.
In earlier releases,
Galera searched for the Controller node with the lowest node-id value
and made that the Primary Controller.
This created problems when a new controller that had a lower node-id value
was added to an existing Controller cluster
and became the Primary Controller,
which conflicted with the existing Primary Controller in the cluster.
Persisting the Primary role in the database solves this problem.
If you delete the "conflicts:" and "compute" line
and redeploy nailgun,
you can deploy a bare-metal deployment
that runs on a single server.
.. warning:: Deploying Fuel on VirtualBox is a much better
way to install Fuel on minimal hardware
for demonstration purposes
than using this procedure.
Be extremely careful when using this "all-in-one" deployment;
if you create too many VM instances,
they may consume all the available CPUs,
causing serious problems accessing the MySQL database.
Resource-intensive services
such as Ceilometer with MongoDB, Zabbix,
and Ceph are also apt to cause problems
when OpenStack is deployed on a single server.
