Hi Thanks for the question.

Yes heat do support deploying an application on the launched VM

Follow this URL for you reference:

You can write the shell commands to be executed under templates section of user_data

Thanks, Nish Patwa

You could use user_data to get cloud-init to run whatever you need to deploy your application. Here is an example.

Another way is to use Heat's Software Deployments. There are dozens of examples of this available too. Note that this requires certain agents to be baked in to the image.

Hi Reeni,

Answering your first question: Yes, you can deploy an application with a VM launch. In your HEAT template, include this section for that particular VM.

user_data:
  str_replace:
    template: |
      < your script for ur application >

Your second question: Yes you can decide for which VM you want to run this script. Just include the above section for the machines of your choice.

The generic syntax for your use case would be:

my_instance:
  type: OS::Nova::Server
  depends_on: <..>
  properties: 
    networks: <..>
    user_data_format: RAW
    user_data:
      str_replace:
        template: |
        params:
