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 network +- cidr: the CIDR 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 CIDR 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 CIDR + 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". + +* [1] https://docs.mirantis.com/openstack/fuel/fuel-8.0/file-ref.html#fuel-file-reference-pages +* [2] https://wiki.openstack.org/wiki/Fuel/Plugins + + +## The "Settings" section + +This looks like user interface stuff and default settings.
