Hi

I have been using HEAT template to create 3 servers and it works just fine

Example:

  ALIS-MF-01:
    type: OS::Nova::Server
    properties:
      name: ALIS-MF-01
      …
       template: {get_file: alis-mf-script.sh }
          params:
            …
            $alis_mf_hostname: { get_param: alis_mf_01_hostname }
            ...

  ALIS-MF-02:
    type: OS::Nova::Server
    properties:
      name: ALIS-MF-02
      …
       template: {get_file: alis-mf-script.sh }
          params:
            …
            $alis_mf_hostname: { get_param: alis_mf_02_hostname }
            ...

  ALIS-MF-03:
    type: OS::Nova::Server
    properties:
      name: ALIS-MF-03
      …
       template: {get_file: alis-mf-script.sh }
          params:
            …
            $alis_mf_hostname: { get_param: alis_mf_03_hostname }
            ...

Which as I said works just fine. Note: alis_mf_01_hostname, alis_mf_02_hostname and alis_mf_03_hostname are provided by my environment file

Now I would like to use Heat::ResourceGroup

  alis_af_rg:
    type: OS::Heat::ResourceGroup
    properties:
      count: { get_param: alis_af_count }
      resource_def:
        type: aqsa_alis_af.yaml
        properties:
           …
          alis_mf_hostname: { get_param: alis_mf_hostname }

The question is, before using Nova:Server, I could distinct the hostname as I was creating 3 different instances (alis_mf_01_hostname, alis_mf_02_hostname and alis_mf_03_hostname)

How can I provide a different hostname using ResourceGroup?

Anybody please?

Just for the story: I already did my research here and couldn't any clue.
