Yaml: Not able to use list_join in for_each construct

[Murali G D]

 Hi,

 Please see following YAML Template

    heat_template_version: 2015-04-30
    description: Distributed Appliance
    parameters:
      image:
        type: string
        description: Image used for servers
        default: 5d2ef44f-e2cb-4292-99cc-b282a0b5730f
      flavor:
        type: string
        description: flavor used by the servers
        default: DefaultFlavorTemplate
      user_data:
        type: string
        description: Server user_data
        default: HelloWorld
      mgmt_network:
        type: string
        description: Mgmt Network used by the server
        default: '67cbf03b-a8c9-4869-8a7c-ed0a52ee64a3'
      mgmt_fabric_network:
        type: string
        description: Fabric Mgmt Network used by the server
        default: '6f7f1f0e-dd98-4e24-aca3-824403feebdb'
      data_fabric_network:
        type: string
        description: Fabric Data Network used by the server
        default: '5d789666-7e58-40f4-bd35-885fc98f46f4'
      external_networks:
        type: string
        type: comma_delimited_list
        label: external networks
        default: 'fa0669c0-14b0-499a-bd53-735110ee40ca,3e393ce9-1526-4a1e-a654-efbd2779f438'

    resources:
      server:
        type: OS::Nova::Server
        properties:
          flavor: {get_param: flavor}
          image: {get_param: image}
          user_data: {get_param: user_data}
          user_data_format: RAW

          networks: #Option1
           - network: {get_param: mgmt_network}
           - network: {get_param: mgmt_fabric_network}
           - network: {get_param: data_fabric_network}
           repeat:
            for_each:
             extnetwork%: {get_param: external_networks}
            template:
             network: extnetwork%

          networks: #Option2
           repeat:
            for_each:
             extnetwork%: {get_param: mgmt_network} {get_param: mgmt_fabric_network} {get_param: data_fabric_network} {get_param: external_networks}
            template:
             network: extnetwork%

          networks: #Option3
           repeat:
            for_each:
             extnetwork%: {list_join: [',' , [{get_param: mgmt_network} , {get_param: mgmt_fabric_network} , {get_param: data_fabric_network} , {get_param: external_networks} ]]}
            template:
             network: extnetwork%

    outputs:
      server_ip:
        description: IP Address of the server.
        value: { get_attr: [server, first_address] }

Basically I want my Nova::Server to be connected to networks in order of - mgmt_network, mgmt_fabric_network, data_fabric_network and then a comma separated list of other external_networks as mentioned in parameters defaults. I am not able to achieve this. I have mentioned 3 options I tried under networks but none of them worked for me.

OpenStack Version: Kilo. HEAT 0.3.0.

    Resolve arguments to 'repeat' function at runtime

    This fixes a regression caused by a7c4b2332f9d1accaa89b51fbc3b09014995983a
    in evaluating the 'for_each' argument too early (at parse time - before the
    result of runtime functions like get_attr are available), while preserving
    the fix for bug 1466748 in allowing intrinsic functions to be used in the
    argument.
