Dmitriy Rabotyagov 82d7c034a0 Split neutron server and neutron agent hosts 
It is very common usecase when neutron-api is intended to run on
infra hosts (inside lxc containers), while neutron-agents are to run on
independent network nodes.

That was not possible by default, so env.d overrides has to be placed
to fix this behaviour. This patch brings option to do this natively
without extra override.

In the meanwhile it shouldn't break any existing depoyments as leaves
previous groups naming as is.

# Overview
# ========
#
# This file contains the configuration for OpenStack Ansible Deployment
# (OSA) core services. Optional service configuration resides in the
# conf.d directory.
#
# You can customize the options in this file and copy it to
# /etc/openstack_deploy/openstack_user_config.yml or create a new
# file containing only necessary options for your environment
# before deployment.
#
# OSA implements PyYAML to parse YAML files and therefore supports structure
# and formatting options that augment traditional YAML. For example, aliases
# or references. For more information on PyYAML, see the documentation at
#
# http://pyyaml.org/wiki/PyYAMLDocumentation
#
# Configuration reference
# =======================
#
# Level: cidr_networks (required)
# Contains an arbitrary list of networks for the deployment. For each network,
# the inventory generator uses the IP address range to create a pool of IP
# addresses for network interfaces inside containers. A deployment requires
# at least one network for management.
#
# Option: <value> (required, string)
# Name of network and IP address range in CIDR notation. This IP address
# range coincides with the IP address range of the bridge for this network
# on the target host.
#
# Example:
#
# Define networks for a typical deployment.
#
# - Management network on 172.29.236.0/22. Control plane for infrastructure
# services, OpenStack APIs, and horizon.
# - Tunnel network on 172.29.240.0/22. Data plane for project (tenant) VXLAN
# networks.
# - Storage network on 172.29.244.0/22. Data plane for storage services such
# as cinder and swift.
#
# cidr_networks:
# container: 172.29.236.0/22
# tunnel: 172.29.240.0/22
# storage: 172.29.244.0/22
#
# Example:
#
# Define additional service network on 172.29.248.0/22 for deployment in a
# Rackspace data center.
#
# snet: 172.29.248.0/22
#
# --------
#
# Level: used_ips (optional)
# For each network in the 'cidr_networks' level, specify a list of IP addresses
# or a range of IP addresses that the inventory generator should exclude from
# the pools of IP addresses for network interfaces inside containers. To use a
# range, specify the lower and upper IP addresses (inclusive) with a comma
# separator.
#
# Example:
#
# The management network includes a router (gateway) on 172.29.236.1 and
# DNS servers on 172.29.236.11-12. The deployment includes seven target
# servers on 172.29.236.101-103, 172.29.236.111, 172.29.236.121, and
# 172.29.236.131. However, the inventory generator automatically excludes
# these IP addresses. The deployment host itself isn't automatically
# excluded. Network policy at this particular example organization
# also reserves 231-254 in the last octet at the high end of the range for
# network device management.
#
# used_ips:
# - 172.29.236.1
# - "172.29.236.100,172.29.236.200"
# - "172.29.240.100,172.29.240.200"
# - "172.29.244.100,172.29.244.200"
#
# --------
#
# Level: global_overrides (required)
# Contains global options that require customization for a deployment. For
# example, load balancer virtual IP addresses (VIP). This level also provides
# a mechanism to override other options defined in the playbook structure.
#
# Option: internal_lb_vip_address (required, string)
# Load balancer VIP for the following items:
#
# - Local package repository
# - Galera SQL database cluster
# - Administrative and internal API endpoints for all OpenStack services
# - Glance registry
# - Nova compute source of images
# - Cinder source of images
# - Instance metadata
#
# Option: external_lb_vip_address (required, string)
# Load balancer VIP for the following items:
#
# - Public API endpoints for all OpenStack services
# - Horizon
#
# Option: management_bridge (required, string)
# Name of management network bridge on target hosts. Typically 'br-mgmt'.
#
# Level: provider_networks (required)
# List of container and bare metal networks on target hosts.
#
# Level: network (required)
# Defines a container or bare metal network. Create a level for each
# network.
#
# Option: type (required, string)
# Type of network. Networks other than those for neutron such as
# management and storage typically use 'raw'. Neutron networks use
# 'flat', 'vlan', or 'vxlan'. Coincides with ML2 plug-in configuration
# options.
#
# Option: container_bridge (required, string)
# Name of unique bridge on target hosts to use for this network. Typical
# values include 'br-mgmt', 'br-storage', 'br-vlan', 'br-vxlan', etc.
#
# Option: container_interface (required, string)
# Name of unique interface in containers to use for this network.
# Typical values include 'eth1', 'eth2', etc. This option is OPTIONAL
# for Neutron provider network definitions when Neutron agents are
# deployed on bare metal (default), but REQUIRED when agents are
# deployed in containers and for all other non-Neutron use-cases.
# NOTE: Container interface is different from host interfaces.
#
# Option: container_type (required, string)
# Name of mechanism that connects interfaces in containers to the bridge
# on target hosts for this network. Typically 'veth'.
#
# Option: host_bind_override (optional, string)
# Name of the physical network interface on the same L2 network being
# used with the br-vlan device. This host_bind_override should only
# be set for the ' container_bridge: "br-vlan" '.
# This interface is optional but highly recommended for vlan based
# OpenStack networking.
# If no additional network interface is available, a deployer can create
# a veth pair, and plug it into the br-vlan bridge to provide
# this interface. An example could be found in the aio_interfaces.cfg
# file.
#
# Option: container_mtu (optional, string)
# Sets the MTU within LXC for a given network type.
#
# Option: ip_from_q (optional, string)
# Name of network in 'cidr_networks' level to use for IP address pool. Only
# valid for 'raw' and 'vxlan' types.
#
# Option: address_prefix (option, string)
# Override for the prefix of the key added to each host that contains IP
# address information for this network. By default, this will be the name
# given in 'ip_from_q' with a fallback of the name of the interface given in
# 'container_interface'.
# (e.g., 'ip_from_q'_address and 'container_interface'_address)
#
# Option: is_container_address (required, boolean)
# If true, the load balancer uses this IP address to access services
# in the container. Only valid for networks with 'ip_from_q' option.
#
# Option: group_binds (required, string)
# List of one or more Ansible groups that contain this
# network. For more information, see the env.d YAML files.
#
# Option: reference_group (optional, string)
# An Ansible group that a host must be a member of, in addition to any of the
# groups within 'group_binds', for this network to apply.
#
# Option: net_name (optional, string)
# Name of network for 'flat' or 'vlan' types. Only valid for these
# types. Coincides with ML2 plug-in configuration options.
#
# Option: range (optional, string)
# For 'vxlan' type neutron networks, range of VXLAN network identifiers
# (VNI). For 'vlan' type neutron networks, range of VLAN tags. Supports
# more than one range of VLANs on a particular network. Coincides with
# ML2 plug-in configuration options.
#
# Option: static_routes (optional, list)
# List of additional routes to give to the container interface.
# Each item is composed of cidr and gateway. The items will be
# translated into the container network interfaces configuration
# as a `post-up ip route add <cidr> via <gateway> || true`.
#
# Option: gateway (optional, string)
# String containing the IP of the default gateway used by the
# container. Generally not needed: the containers will have
# their default gateway set with dnsmasq, poitining to the host
# which does natting for container connectivity.
#
# Example:
#
# Define a typical network architecture:
#
# - Network of type 'raw' that uses the 'br-mgmt' bridge and 'management'
# IP address pool. Maps to the 'eth1' device in containers. Applies to all
# containers and bare metal hosts. Both the load balancer and Ansible
# use this network to access containers and services.
# - Network of type 'raw' that uses the 'br-storage' bridge and 'storage'
# IP address pool. Maps to the 'eth2' device in containers. Applies to
# nova compute and all storage service containers. Optionally applies to
# to the swift proxy service.
# - Network of type 'vxlan' that contains neutron VXLAN tenant networks
# 1 to 1000 and uses 'br-vxlan' bridge on target hosts. Applies to all
# neutron agents on bare metal hosts.
# - Network of type 'vlan' that contains neutron VLAN networks 101 to 200
# and 301 to 400 and uses the 'br-vlan' bridge on target hosts. Applies
# to all neutron agent containers and neutron agents on bare metal hosts.
# - Network of type 'flat' that contains one neutron flat network and uses
# the 'br-vlan' bridge on target hosts. Maps to the 'eth12' device in
# containers. Applies to all neutron agent containers and neutron agents
# on bare metal hosts.
#
# Note: A pair of 'vlan' and 'flat' networks can use the same bridge because
# one only handles tagged frames and the other only handles untagged frames
# (the native VLAN in some parlance). However, additional 'vlan' or 'flat'
# networks require additional bridges.

# --------
#
# Level: log_hosts (optional)
# List of target hosts on which to deploy logging services. Recommend
# one minimum target host for this service.
#
# Level: <value> (required, string)
# Hostname of a target host.
#
# Option: ip (required, string)
# IP address of this target host, typically the IP address assigned to
# the management bridge.
#
# Example:
#
# Define a logging host:
#
# log_hosts:
# log1:
# ip: 172.29.236.171
#
# --------
#
# Level: haproxy_hosts (optional)
# List of target hosts on which to deploy HAProxy. Recommend at least one
# target host for this service if hardware load balancers are not being
# used.
#
# Level: <value> (required, string)
# Hostname of a target host.
#
# Option: ip (required, string)
# IP address of this target host, typically the IP address assigned to
# the management bridge.
#
#
# Example:
#
# Define a virtual load balancer (HAProxy):
#
# While HAProxy can be used as a virtual load balancer, it is recommended to use
# a physical load balancer in a production environment.
#
# haproxy_hosts:
# lb1:
# ip: 172.29.236.100
# lb2:
# ip: 172.29.236.101
#
# In case of the above scenario(multiple hosts),HAProxy can be deployed in a
# highly-available manner by installing keepalived.
#
# To make keepalived work, edit at least the following variables
# in ``user_variables.yml``:
# haproxy_keepalived_external_vip_cidr: 192.168.0.4/25
# haproxy_keepalived_internal_vip_cidr: 172.29.236.54/16
# haproxy_keepalived_external_interface: br-flat
# haproxy_keepalived_internal_interface: br-mgmt
#
# To always deploy (or upgrade to) the latest stable version of keepalived.
# Edit the ``/etc/openstack_deploy/user_variables.yml``:
# keepalived_package_state: latest
#
# The group_vars/all/keepalived.yml contains the keepalived
# variables that are fed into the keepalived role during
# the haproxy playbook.
# You can change the keepalived behavior for your
# deployment. Refer to the ``user_variables.yml`` file for
# more information.
#
# Keepalived can ping a public and private IP address to check its status. To
# enable this feature, set the ``keepalived_external_ping_address`` and
# ``keepalived_internal_ping_address`` variables in the ``user_variables.yml``
# file.
