How to convert a text area to list of disks for vmware_guest

Hello guys:

There’s something I’ve been struggling with for some hours without knowing exactly how to solve it.
Through AWX, I want users to enter the size of disks for a virtual machine using a text area in a survey, like this:

100
20
130
230

When I assign this input to a variable, I see that ansible converts them to a list, like this:

mydisks: |-
100
20
130
230

By using vmware_guest module, I’d like to convert it to something like…

vmware_guest:
disk:

  • size_gb: 100
    type: None

  • size_gb: 20
    type: None

  • size_gb: 130
    type: None

  • size_gb: 230
    type: None

So I found some references on Internet that look like this jinja2 expressions:

vmware_guest:
disk: >-
[{% for size in mydisks.split() %}‘{ size_gb: {{ size }}, type: None }’, {% endfor %}]

However, when I run the playbook I got an ugly error like this:

TASK [Create virtual machine] ********************************************************************************************************************************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: AttributeError: ‘str’ object has no attribute ‘get’

Would someone, please, help me with this issue? I’m sure my jinja2 expression it’s wrong, but I can figure out what’s the right way to do it.

Thanks in advance

With set_fact you can do this

- set_fact:
    disk: "{{ disk | default() + [{ 'size_gb': item, 'type': 'None' }] }}"
  with_items: '{{ mydisks.split() }}'

Thank you so much, Kai. This worked perfectly!
