scaleway_user_data: multiline is broken, cloud-init doesn't work

[jackivanov]

SUMMARY

There should be multiline in the cloud-init field, but instead either the module or API itself breaks it and sends the whole text as a string in double quotes.

CONFIGURATION

OS / ENVIRONMENT

STEPS TO REPRODUCE

  - scaleway_user_data:
      server_id: "{{ scaleway_compute.msg.id }}"
      region: "{{ region }}"
      user_data:
        cloud-init: |
          #cloud-config
          # final_message
          # default: cloud-init boot finished at $TIMESTAMP. Up $UPTIME seconds
          # this message is written by cloud-final when the system is finished
          # its first boot
          final_message: "The system is finally up, after $UPTIME seconds"

1. Update the cloud-init and start the server
2. Cloud-init throws an error

a workaround for now is to use the uri module:

- uri:
    url: "https://cp-{{ region }}.scaleway.com/servers/{{ server_id }}/user_data/cloud-init"
    method: PATCH
    body: "{{ lookup('template', 'cloud-config.yml') }}"
    status_code: 204
    headers:
      Content-Type: "text/plain"
      X-Auth-Token: "{{ token }}"
