Hi, I have trying to execute cloud init script (post boot), but not sure how to provide the file path. part of the template looks like this. Also "heat-preview" shows that, always file mentioned in default section of "parameter" is passed to resources, thought we pass different file name from "environemnt.yaml" file.

        type: string

      config_drive: "true"
      user_data : 
          template: |
            { get_file : }
            $config_file: { get_param: config_file }

In my case " " is placed in same directory where launcher.yaml and environment.yaml files are located.

You will have to use OS::Heat::SoftwareConfig or OS::Heat::SoftwareComponent to do that.

OS::Heat::SoftwareComponent - to be used when you want to execute different scripts over the lifecycle of VM (for instance when it will be created, updated, suspended , resumed) see this (OS::Heat::SoftwareComponent example)

OS::Heat::SoftwareConfig to be used when you want to do a simple configuration via some script one time, without taking lifecycle of VM / script into account. Search for its example and you'll get some good material.
