Fuel File Reference PagesThis section provides reference pages for select configuration files that Fuel uses.
Warning
Be very careful when modifying the configuration files. A simple typo when editing these files may
severely damage your environment.
When you modify the YAML files, you will receive a warning that some attributes were modified from the
outside. Some features may become inaccessible from the UI after you do this.
These pages are under development; the information presented here has been reviewed but may not be
complete.

astute.yaml -- Target nodes
Target 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 target node when it is deployed by mcollective and must not bedeleted. Facter extension reads data from this file and uses it to create the $::fuel_settings data structure. Thisstructure 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 nodein the astute.yaml file; one node is designated the primary-mongo node and all other nodes have just mongospecified for the role. Ideally, you should have one MongoDB node for each Controller node in the environment.
You can use the Fuel Web UI to deploy as many MongoDB nodes as you like when you initially create your
environment. You must edit this file and use command line tools to add MongoDB nodes to a deployedenvironment; seeAdd a MongoDB node for instructions.
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_netmas
k:
Netmask used for the Internal logical network.
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 onesection like this for each configured MongoDB node:

engine.yaml
Fuel Master Node:/root/provisioning_1
The engine.yaml file defines the basic configuration of the target nodes that Fuel deploys for the OpenStackenvironment. 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
1. Dump provisioning information using thisfuel CLI command:
fuel --env 1 provisioning default
where --env 1 should be set to the specific environment (id=1 in this example).
2. Edit file.
3. Upload the modified file:
fuel --env-1 provisioning upload
Description
The engine.yaml file defines the provisioning engine being used (Cobbler by default) along with the password andURLs used to access it.

dnsmasq.template
Fuel Master Node:/etc/cobbler/dnsmasq.template
The dnsmasq.template file defines the DHCP networks used for Multiple Cluster Networks. The networks listed heremust match thefuelweb_admin networks that are defined in Fuel.
Usage
1. Log into the cobbler Docker containers and dockerctl container:
dockerctl shell cobbler
2. Edit file.
vi /etc/cobbler/dnsmasq.template
3. Rebuild the dnsmasq configuration and reload it:
cobbler sync
4. Exit the Cobbler docker container:
exit
File Format
Eachfuelweb_admin network must be defined in this file:
dhcp-range=,,,,[]
dhcp-option=net:,option:router,
dhcp-boot=net:,pxelinux.0,boothost,
env-name: Unique name of this network in dnsmasq
start-IP-addr: Starting IP address of DHCP range
end-IP-addr: Ending IP address of DHCP range
netmask: Netmask for DHCP network
leasetime: DHCP lease time; default value is 60 minutes
IP-addr-of-gateway:
IP address of gateway (router) in the network segment
Fuel-Master-IP-a
ddr:
IP address of the Fuel Master node

dhcp-option=net:alpha,option:router,10.110.1.65
dhcp-boot=net:alpha,pxelinux.0,boothost,10.110.0.2
The network must forward the DHCP packets for the other logical networks that are defined in the network_1.yamlfile. It is also possible to set up a proxy using the Linux dhcp-helper program so that the target nodes can boot.
Note that the dnsmasq.template file is managed by Puppet so all changes are overwritten/removed when thePuppet container is restarted or the Fuel Master node is rebooted.

network_1.yaml
Fuel Master Node:/root/network_1.yaml
The network_1.yaml file contains the network configuration information for the environment.
To implement Multiple Cluster Networks, follow the instructions in Configuring Multiple Cluster Networks to createadditional Node Groups, then download this file and configure the new Network Group(s).
Usage
1. Dump network information using thisfuel CLI command:
fuel --env 1 network --download
where --env 1 points to the specific environment (id=1 in this example).
2. Edit file and add information about the new Network Group(s).
3. Upload the modified file:
fuel --env-1 network --upload
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 thandocumented 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 section
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 OpenStackenvironment. 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
1. Log into the nailgun Docker containers and dockerctl container:
dockerctl shell nailgun
2. Edit file.
3. Run the following commands to Nailgun to reread its settings and restart:
manage.py dropdb && manage.py syncdb && manage.py loaddefault
killall nailgund
4. Exit the Nailgun docker container:
exit
File Format
The openstack.yaml file contains a number of blocks, each of which may contain multiple parameters. The majorones 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.
modes-metadata section
Lists each of the roles available on theAssign a role or roles to each node server screen with the description. Notethat 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 (see How Nodes are Defined and Managed) andmade 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.

settings.yaml
Fuel Master Node:/root/settings_x.yaml/
The settings.yaml file contains the current values for the information on the Settings page of the Fuel UI.
Usage
1. Dump provisioning information using thisfuel CLI command:
fuel --env 1 settings default
where --env 1 that to the specific environment (id=1 in this example).
2. Edit file.
3. Upload the modified file:
fuel --env-1 settings upload
