description: >
Software Config to drive os-net-config for a simple bridge configured with a
static IP address for the ctlplane network with optionally the admin and
public IPs too.
parameters:
ControlPlaneIp:
default: ''
description: IP address/subnet on the ctlplane network
type: string
{%- for network in networks %}
{{network.name}}IpSubnet:
default: ''
description: IP address/subnet on the {{network.name_lower}} network
type: string
{{network.name}}InterfaceRoutes:
default: []
description: >
Routes for the {{network.name_lower}} 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
{{network.name}}Mtu:
default: {{network.mtu|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.name}} network.
type: number
{{network.name}}InterfaceDefaultRoute:
default: ''
description: default route for the {{network.name_lower}} network
type: string
{%- endfor %}
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.
type: comma_delimited_list
DnsSearchDomains: # Override this via parameter_defaults
default: []
description: A list of DNS search domains to be added (in order) to resolv.conf.
type: comma_delimited_list
UndercloudLocalMtu: # Override this via parameter_defaults
default: 1500
description: MTU to use for the Undercloud local_interface.
type: number
constraints:
- range: { min: 1000, max: 65536 }
UndercloudNetConfigOverride:
default: {}
description: Custom JSON data to be used to override the os-net-config data in this template. This is meant to be used by net_config_override parameter in tripleoclient to provide an easy means to pass in custom net configs for the Undercloud.
