Heat

Installation and Configuration

Devstack will automatically configure heat to support BGPVPN.

Other deployments need to add the directory for the python networking_bgpvpn_heat module to plugin_dirs in the heat config: /etc/heat/heat.conf.

This directory can be found out with:

dirname $(python -c "import networking_bgpvpn_heat as n;print(n.__file__)")

Examples

Heat Orchestration Template (HOT) example 1

This template has to be run with admin rights and will create a BGPVPN for the current tenant, along with a Network associated with it:

description: BGPVPN networking example (admin)
heat_template_version: '2013-05-23'

resources:

  BGPVPN1:
    type: OS::Neutron::BGPVPN
    properties:
        import_targets: [ "100:1001"]
        export_targets: [ "100:1002"]
        route_targets: [ "100:1000" ]
        name: "default VPN"

  Net1:
    type: OS::Neutron::Net

  SubNet1:
    type: OS::Neutron::Subnet
    properties:
       network: { get_resource: Net1 }
       cidr: 192.168.10.0/24

  BGPVPN_NET_assoc1:
    type: OS::Neutron::BGPVPN-NET-ASSOCIATION
    properties:
        bgpvpn_id: { get_resource: BGPVPN1 }
        network_id: { get_resource: Net1 }

In devstack, this HOT file can be used with cloud admin privileges in the demo project; such privileges can be obtained with the command:

source openrc admin demo

This example can then be run:

$ heat stack-create networks -f bgpvpn_test-00.yaml

Heat Orchestration Template (HOT) example 2

This is a set of two templates:

• one that has to be run with admin rights and will create a BGPVPN for the ‘demo’ tenant:

  description: BGPVPN networking example (admin)
  heat_template_version: '2013-05-23'
  
  resources:
    BGPVPN1:
      type: OS::Neutron::BGPVPN
      properties:
          import_targets: [ "100:1001"]
          export_targets: [ "100:1002"]
          route_targets: [ "100:1000" ]
          name: "default_vpn"
          tenant_id: "demo"
  

  $ source openrc admin admin
  $ heat stack-create bgpvpn -f bgpvpn_test-04-admin.yaml
  

• one to run as a plain ‘demo’ tenant user, that will:

  • create a Network and bind it to the ‘default_vpn’ BGPVPN
  • create a second Network connected to a Router, and bind the Router to the ‘default_vpn’
