**由前面兩天介紹部屬完3GPP管理系統與NFV MANO系統，接下來要介紹VNF的通用樣板，而我們樣板使用TOSCA通用樣板，這點有在ETSI GS NFV-SOL 001裡被定義，因此我們先來介紹TOSCA樣板裡的幾個重要欄位，首先先來看一般VNF的通用樣板長的如何。

tosca_definitions_version: tosca_simple_yaml_1_0

topology_template:
  node_templates:
    VNF1:
      type: tosca.nodes.nfv.VNF
      properties:
        descriptor_id: 367f45fd-1dd2-11b2-8000-08002mongodb
        descriptor_version: 1.0
        provider: imac
        product_name: mongodb
        software_version: latest

    VDU1:
      type: tosca.nodes.nfv.Vdu.Compute
      properties:
        sw_image_data:
          name: free5gc-mongodb
          provider: free5gmano
          version: latest
          diskFormat: raw
      capabilities:
        virtual_compute:
          properties:
            virtual_memory:
              virtual_mem_size: 512Mi
            virtual_cpu:
              num_virtual_cpu: 500m
      artifacts:
        sw_image:
          type: tosca.artifacts.nfv.SwImage
          file: free5gmano/nextepc-mongodb
      requirements:
        virtual_storage:
          properties:
            type_of_storage: volume
            size_of_storage: 20Gi
            path_of_storage: /data/db
      attributes:
        namespace: default
        replicas: 1
        name_of_service: mongodb-svc
        ports:
        - 27017

    CP1:
      type: tosca.nodes.nfv.Cpd
      properties:
        layer_protocol: ipv4
      requirements:
        virtual_binding: VDU1
        virtual_link: VL1

    VL1:
      type: tosca.nodes.nfv.VnfVirtualLink
      properties:
        network_name: management
        vl_profile:
          virtual_link_protocol_data:
            l3_protocol_data:
              dhcp_enabled: False

如果英文好一點的 可能已經可以看出大概是如何運作的，首先VNF的欄位 會填入VNF的ID名稱與版本等訊息
VDU 則會填入這個VNF部屬時需要的資訊 如使用的IMAGE,需要的空間，CPU與記憶體的使用量，跟要開放出來的port號等
最後CP與VL則是定義這個VNF的網路的設定資訊
而除了VNF的描述檔 我們還需要子網路切片的描述檔 告訴NFVO我們部屬的子網路切片有那些VNF，這個名稱統稱為NSD

tosca_definitions_version: tosca_simple_yaml_1_2

topology_template:
  node_templates:
    NS1:
      type: tosca.nodes.nfv.NS
      properties:
        descriptor_id: 1b4dd4c7-1dd2-11b2-8000-080027b246c3
        designer: imac
        version: 1.0
        name: free5gc-stage3.2.1-amd64
        invariant_id: 1111-2222-aaaa-bbbb
        constituent_vnfd:
          - vnfd_id: 367f45fd-1dd2-11b2-8001-080027b24amf
          - vnfd_id: 367f45fd-1dd2-11b2-8001-080027b2ausf
          - vnfd_id: 367f45fd-1dd2-11b2-8001-080027b24nrf
          - vnfd_id: 367f45fd-1dd2-11b2-8001-080027b2nssf
          - vnfd_id: 367f45fd-1dd2-11b2-8001-080027b24pcf
          - vnfd_id: 367f45fd-1dd2-11b2-8008-080027b24smf
          - vnfd_id: 367f45fd-1dd2-11b2-8006-080027b24udm
          - vnfd_id: 367f45fd-1dd2-11b2-8004-080027b24udr
          - vnfd_id: 367f45fd-1dd2-11b2-8002-080027b24upf
          - vnfd_id: 367f45fd-1dd2-11b2-8000-08002mongodb
          - vnfd_id: 367f45fd-1dd2-11b2-8002-080027b25webui

除了NSD自己的ID與資訊，我們還需要填入剛剛可以看到的VNF的ID
最後我們還需要告訴NFVO他所能需要的資源型態 也就是NRM

最後將這三份 分別包成ZIP檔，上傳至free5gmano進行部屬，若沒發生錯誤且可以看到k8s上有pod被建立，及代表部屬成功，這部分會在下周實際包一份free5gc進行部屬測試
