Software Config to drive os-net-config with 2 bonded nics on a bridge.
parameters:
BondInterfaceOvsOptions:
default: ''
description: The ovs_options or bonding_options string for the bond
interface. Set things like lacp=active and/or bond_mode=balance-slb
for OVS bonds or like mode=4 for Linux bonds using this option.
type: string
constraints:
- allowed_pattern: ^((?!balance.tcp).)*$
description: The balance-tcp bond mode is known to cause packet loss and
should not be used in BondInterfaceOvsOptions.
ControlPlaneIp:
default: ''
description: IP address/subnet on the ctlplane network
type: string
ControlPlaneSubnetCidr:
default: ''
description: >
The subnet CIDR of the control plane network. (The parameter is
automatically resolved from the ctlplane subnet's cidr attribute.)
type: string
ControlPlaneDefaultRoute:
default: ''
description: The default route of the control plane network. (The parameter
is automatically resolved from the ctlplane subnet's gateway_ip attribute.)
type: string
ControlPlaneStaticRoutes:
default: []
description: >
Routes for the ctlplane network traffic.
JSON route e.g. [{'destination':'10.0.0.0/16', 'nexthop':'10.0.0.1'}]
Unless the default is changed, the parameter is automatically resolved
from the subnet host_routes attribute.
type: json
ControlPlaneMtu:
default: 1500
description: The maximum transmission unit (MTU) size(in bytes) that is
guaranteed to pass through the data path of the segments in the network.
(The parameter is automatically resolved from the ctlplane network's mtu attribute.)
type: number
DnsServers: # Override this via parameter_defaults
default: []
description: >
DNS servers to use for the Overcloud (2 max for some implementations).
If not set the nameservers configured in the ctlplane subnet's
dns_nameservers attribute will be used.
