Open Stack

Hi,

first of all the syntax of the command you are using is wrong, right way to
use multiple parameters in one argument would be

--parameters flavor_1=some_flavor_1_name;flavor2=some_flavor_2_name;...

or you can use it multiple times

--parameters flavor_1=some_flavor_1_name --parameters
flavor2=some_flavor_2_name

Then, if your template defines say 2 server resources with parameters
section as given in your snippet (I get that you use HOT yaml templates),
each of them referencing its own flavor parameter like

resources:
  server_1:
    type: OS::Nova::Server
    properties:
      flavor: { get_param: flavor_1 }
....
  server_2:
    type: OS::Nova::Server
    properties:
      flavor: { get_param: flavor_2 }
....

everything should work.

BTW, what is the Heat / OpenStack version you are using?

Best regards,
Pavlo Shchelokovskyy.
