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: (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'. # # Option: tunnel_bridge (optional, string) # Name of tunnel network bridge on target hosts. Typically 'br-vxlan'. # # 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. # 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 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: 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: is_ssh_address (required, boolean) # If true, Ansible uses this IP address to access the container via SSH. # 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: 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 via || 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. Maps to the # 'eth10' device in containers. Applies to all neutron agent containers # and 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. Maps to # the 'eth11' device in containers. 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. # # provider_networks: # - network: # group_binds: # - all_containers # - hosts # type: "raw" # container_bridge: "br-mgmt" # container_interface: "eth1" # container_type: "veth" # ip_from_q: "container" # is_container_address: true # is_ssh_address: true # - network: # group_binds: # - glance_api # - cinder_api # - cinder_volume # - nova_compute # # Uncomment the next line if using swift with a storage network. # # - swift_proxy # type: "raw" # container_bridge: "br-storage" # container_type: "veth" # container_interface: "eth2" # container_mtu: "9000" # ip_from_q: "storage" # - network: # group_binds: # - neutron_linuxbridge_agent # container_bridge: "br-vxlan" # container_type: "veth" # container_interface: "eth10" # container_mtu: "9000" # ip_from_q: "tunnel" # type: "vxlan" # range: "1:1000" # net_name: "vxlan" # - network: # group_binds: # - neutron_linuxbridge_agent # container_bridge: "br-vlan" # container_type: "veth" # container_interface: "eth11" # type: "vlan" # range: "101:200,301:400" # net_name: "vlan" # - network: # group_binds: # - neutron_linuxbridge_agent # container_bridge: "br-vlan" # container_type: "veth" # container_interface: "eth12" # host_bind_override: "eth12" # type: "flat" # net_name: "flat" # # -------- # # Level: shared-infra_hosts (required) # List of target hosts on which to deploy shared infrastructure services # including the Galera SQL database cluster, RabbitMQ, and Memcached.
