  PortMap:
    description: |
      PortMap describes the mapping of container ports to host ports, using the
      container's port-number and protocol as key in the format `<port>/<protocol>`,
      for example, `80/udp`.

      If a container's port is mapped for both `tcp` and `udp`, two separate
      entries are added to the mapping table.
    type: "object"
    additionalProperties:
      type: "array"
      items:
        $ref: "#/definitions/PortBinding"
    example:
      "443/tcp":
        - HostIp: "127.0.0.1"
          HostPort: "4443"
      "80/tcp":
        - HostIp: "0.0.0.0"
          HostPort: "80"
        - HostIp: "0.0.0.0"
          HostPort: "8080"
      "80/udp":
        - HostIp: "0.0.0.0"
          HostPort: "80"
      "53/udp":
        - HostIp: "0.0.0.0"
          HostPort: "53"
      "2377/tcp": null

  PortBinding:
    description: |
      PortBinding represents a binding between a host IP address and a host
      port.
    type: "object"
    x-nullable: true
    properties:
      HostIp:
        description: "Host IP address that the container's port is mapped to."
        type: "string"
        example: "127.0.0.1"
      HostPort:
        description: "Host port number that the container's port is mapped to."
        type: "string"
        example: "4443"

  Ports:

Fixing in the mustache template is not possible, because apparently the models are not parsed correctly.
So the 'vars' variable used while creating the members of the model does not contain the data to generate the model with the correct members.

I think this also affects other langs

I need help to fix this. Can someone please give me some hints?

@etherealjoy I'll try to take a look this weekend.

Can you please try other generators (e.g. cpprest, ruby) to see if it has similar issues?

cpprest, the PortMap Members is blank, same issue.

cpprest suffer from an additional problem listed here #7053
Ruby seems to have the same problem, the class is created but no members referencing the PortBinding type.
