openstack_user_config settings reference¶
The openstack_user_config.yml.example file is heavily commented with the
details of how to do more advanced container networking configuration. The
contents of the file are shown here for reference.
#
# 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 (or valid FQDN) 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 (or valid FQDN) for the following items:
#
# - Public API endpoints for all OpenStack services
# - Horizon
#
# Option: management_bridge (required, string)

#
# 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_bridge_type (optional, string)
# Type of container_bridge on target hosts. This option should only set
# to "openvswitch" when the container_bridge is set up with openvswitch.
# The default value is undefined, which means bridge type is linux bridge.
#
# 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_management_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: 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.
