description: >
  Software Config to drive os-net-config for a simple bridge configured with a
  static IP address for the ctlplane network.
parameters:
  ControlPlaneIp:

    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.

  ControlPlaneSubnetCidr:

    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.

    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.

  StandaloneNetConfigOverride:
    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 a standalone node.
    type: json
  EC2MetadataIp: # Here for compatability, not used.
