Hi colleagues,

I'm using the following way to pass cloud-init info into VM:

  n2:
    type: OS::Nova::Server
    properties:
     [ ... ]
      user_data_format: SOFTWARE_CONFIG
      user_data:
          str_replace:
            template: { get_file: CI-v17.yaml }
            params:
              NTFY: { get_attr: ['wait_handle', 'curl_cli'] }

where CI-v17.yaml is the following:

#cloud-config

[ ... ]
timezone: Europe/Kiev
runcmd:
  - NTFY --data-binary '{"status": "SUCCESS"}'
[ ... ]

Unfortunatelty, NTFY expands to something that contains YAML control sequence ": " (colon+space e.g. X-Auth-Token: 'something') which leads to parsing error.

Is there any way to escape this sequence with something that will prevent YAML parsing error? Note that I want to use external file to store cloud-init config since I use it for multiple VMs.

Try to use

  n2-ci:
    type: OS::Heat::CloudConfig
    properties:
      cloud_config:
        str_replace:
          template: { get_file: CI-v17.yaml }
          params:
            NTFY: { get_attr: ['wait_handle', 'curl_cli'] }

  n2:
    type: OS::Nova::Server
    properties:
     [ ... ]
      user_data_format: SOFTWARE_CONFIG
      user_data: { get_resource: n2-ci }

leads to the following Heat error:

ERROR: Property error: : resources.n2-ci.properties.cloud_config: : "#cloud-config [ ... ]" is not a map

I will appreciate any ideas on how to work around this issue.

Thank you.
