+-----------------------------------
+
+This file has several sections, some of the sections are self describing:
+
+```
+title: Deployment Environment Adapter (DEA)
+version:
+comment: Config for LF POD1 - HA deployment with Ceph and Opendaylight
+wanted_release: Kilo on Ubuntu 14.04
+```
+
+## The Environment section
+
+environment:
+ name: opnfv
+ mode: ha # noha, no-ha?
+ net_segment_type: tun # ?
+
+
+## The "Fuel" section
+
+```
+fuel:
+ ADMIN_NETWORK: # Static Fuel admin network configuration
+ cidr: 10.20.0.0/24 # this is the "fuelweb_admin" in the nodes
+ dhcp_gateway: 10.20.0.2 # nodes us this as default gateway
+ dhcp_pool_end: 10.20.0.254 # nodes get addresses from here
+ dhcp_pool_start: 10.20.0.3 # This is the Fuel server IP address
+ ipaddress: 10.20.0.2
+ netmask: 255.255.0.0 # netmask for nodes (otherwise why is it
+ # needed if CIDR above?
+ DNS_DOMAIN: domain.tld #
+ DNS_SEARCH: domain.tld #
+ DNS_UPSTREAM: 8.8.8.8 # Fuel->Network Settings->Other->DNS Servers
+ FUEL_ACCESS:
+ password: admin
+ user: admin
+ HOSTNAME: opnfv
+ NTP1: 0.pool.ntp.org # Fuel->Newtok Setting->Other->NTP server list
+ NTP2: 1.pool.ntp.org
+ NTP3: 2.pool.ntp.org
+```
+
+It would make more sense if NTP was a list:
+
+```
+ NTP:
+ - 0.pool.ntp.org
+ - 1.pool.ntp.org
+ - 2.pool.ntp.org
+```
+
+Now I don't know if NTP4 would be a valid key...
+
+## The "node" section
+
+Then there is the important "node" section:
+
+```
+node:
+ - id: 1
+ interfaces: <some section describing interfaces>
+ transformations: <section describing what to do with the interfaces>
+ role: [controller|compute|cinder|...]
+ - id: 2
+ interfaces: interfaces_1
+ transformations: transformations_1
+ role: ceph-osd,controller
+ ...
+ - id: n
+ ...
+```
+
+Now, the "interfaces" section could be something line:
+
+```
+node:
+ - id: 1
+ interfaces: interfaces_1
+ transformations: transformations_1
+```
+
+## Interfaces
+
+In this case we would have a "section" called intefaces_apm, that looks like:
+
+```
+interfaces_1:
+ eth0:
+ - none # I made this up, I don't know if "none" is valid
+ eth1:
+ - fuelweb_admin
+ eth2:
+ - public
+ - storage # vlan 2010
+ - management # vlan 2011
+ - private # vlan 2012
+```
+
+This is self describing in a way. eth1 is used as the interface for the
+"fuel admin" network, while eth2 will be used for what Fuel calls "public",
+"storage", "management" and "private" networks. These match the networks in
+the "networks" tab in the Fuel dashboard.
+
+## Transformations
+
+For now we won't come into huge detail about the transformations, but they
+seem to contain a list of "commands" issued to ovs-vsctl (Open vSwitch).
+For example:
+
+```
+transformations_1:
+ transformations:
+ - ...
+ - action: add-port
+ bridge: br-mgmt
+ name: eth1.300
+ - ...
+```
+
+Basically the deploy script will issue the command:
+
+```
+ ovs-vsctl add-port br-mgmt eth1.300
+```
+(or ...eth1 tag=300)
+
+## The "network" section:
+
+The networks listed in each of the devices of the "interfaces_1" section
+are defined in the "network" section. Inside the "network" section, there is
+another section called "networks", with a list of networks defined:
+
+```
+network:
+ ...
+ networks:
+ - cidr: 192.168.0.0/24
+ gateway: null
+ ip_ranges:
+ - - 192.168.0.1
+ - 192.168.0.254
+ meta:
+ cidr: 192.168.0.0/24 # TBD: Can it be different from previos CIDR?
+ # Is this the default value in the UI?
+ configurable: true # TBD, UI?
+ map_priority: 2 # TBD, UI?
+ name: management
+ notation: cidr # TBD, UI?
+ render_addr_mask: internal # TBD, UI?
+ render_type: cidr # TBD, UI stuff?
+ use_gateway: false # Only for public net, or for
+ vips: # TBD
+ - haproxy
+ - vrouter
+ vlan_start: 101
+ name: management
+ vlan_start: 300 # must match transformations
+ - cidr: ...
+ ...
+```
+
+Let's take the "management" network as an example. Here we define the
+netmask and several parameters that will look familiar when looking at the
+"Networks" Fuel dashboard tab. The available keys:
+- name: the name of the
+- cdir: the CDIR for this network
+- gateway: an IP address (only for public network?)
+- ip_ranges: a list with the IP ranges available to this network.
+- vlan_start: When using vlan tagging, the first vlan tag
+- meta: (explained below)
+
+The purpose of the "meta" key is less obvious here, and some of the data
+appears to be redundant. My guess is that it is part of Fuel's user
+interface. The CIDR here would be the default and "notation" is probably the
+way it is displayed in the form field:
+
+- cidr: again the same CDIR as above [is this redundant? error prone?]
+- configurable: boolean [?]
+- map_priority: int [?]
+- name: again the same name as above?
+- notation: cidr [any other available keys?]
+- use_gateway: boolean [apparently only "true "if an IP was given above]
+- vips: This seems to be a list of "namespaces" defined later in the
+- "network section".
+- vlan_start same as above...
+
+Now if we look back, in the "interfaces_1" section we had this:
+
+```
+interfaces_1:
+ eth2:
+ - management
+```
+
+This is clearly the network defined above. The same goes for "public",
+"storage" and "private".
+
+## The "network" section continued
+
+Apart from the definition of each of the networks and required by Fuel,
+the "network" section also has a "preamble" with the following parameters
+and corresponding setting in Fuel:
+
+```
+network:
+ management_vip: 192.168.0.2 # TBD (see vips)
+ management_vrouter_vip: 192.168.0.1 # TBD
+ public_vip: 172.30.9.64 # TBD
+ public_vrouter_vip: 172.30.9.65 # TBD
+ networking_parameters: # Fuel->Networ->Settings
+ base_mac: fa:16:3e:00:00:00 # Neutron L2
+ configuration_template: null
+ dns_nameservers: # Neutron L3, guess OS DNS Servers
+ - 8.8.4.4
+ - 8.8.8.8
+ floating_ranges: # Neutron L3, floating Network Param
+ - - 172.30.9.160 # floating IP range start
+ - 172.30.9.254 # floating IP range end
+ gre_id_range: # Neutron L2, what if VXLAN?
+ - 2 # Neutron L2, tunnel ID range start
+ - 65535 # Neutron L2, tunnel ID range end
+ # Neutron L3, Internal Network
+ # Parameters
+ internal_cidr: 192.168.111.0/24 # internal network CDIR
+ internal_gateway: 192.168.111.1 # internal network gateway
+ net_l23_provider: ovs # TBD: must match transformations?
+ segmentation_type: tun # TBD: what options are there? tun/vlan?
+ vlan_range: # TBD
+ - 1000
+ - 1030
+ vips:
+ ...
+```
+
+## The "vips" in the "network" section
+
+In addition to all the above, the network section contains a "vips" section.
+I don't know what they mean, but there are some relations between these
+vips, and the networks defined above:
+
+```
+network:
+ vips:
+ management:
+ ipaddr: 192.168.0.2 # TBD: same as management_vip?
+ namespace: haproxy # TBD: network namespace?
+ network_role: mgmt/vip # TBD
+ node_roles:
+ - controller # Why do we define it here?
+ - primary-controller # for an HA environment?
+ public:
+ ...
+ vrouter:
+ ...
+ vrouter_pub:
+ ...
+```
+
+Also, in contrast to the "networks" section, the "vips" section is not a list,
+but a series of records...
+
+Some Fuel plugins seem to look at this particular setup, one of the examples
+in [2], absolute-dashboard-link.pp, reads:
+
+```
+$os_public_vip = $network_metadata['vips']['public']['ipaddr']
+```
+
+If you remember from above, each network has a "metadata" section, this
+matches the name of the variable $network_metadata. In that section there is
+a "vips" section, that contains a list of "vips", and one of the vips is
+"public", and one of the fields is "ipaddr".

+
+
+## The "Settings" section
+
+This looks like user interface stuff and default settings. For instance:
+settings:
+
+```
+ editable:
+ ...
+ additional_components:
+ ceilometer:
+ description: If selected, Ceilometer component will be installed
+ label: Install Ceilometer
+ type: checkbox
+ value: false
+ weight: 40
+```
+
+This is clearly the label "Install Ceilometer" in the Fuel web dashboard.
+
+This looks like an email label entry with the corresponding regex to
+validate it:
+
+```
+settings:
+ editable:
+ access:
+ email:
+ description: Email address for Administrator
+ label: Email
+ regex:
+ error: Invalid email
+ source: ^\S+@\S+$
+ type: text
+ value: admin@localhost
+ weight: 40
+ ...
+```
+
+## Other
+
+I think most of it, specially the "settings" part, has been machine created.
+It would be nice to recreate one of this files from a manual Fuel
+deployment.
