Create dictionary / list from registered variable in Ansible - windows

Question

Hej *,
I'm writing a playbook which should set some disk attributes in the Windows registry.
All disk attributes are stored under a specific vendor folder. There is a value under each disk folder that I want to change in the end.
- Disk&Ven_QEMU&Prod_QEMU_HARDDISK
|- 00000
|- 00001
- Disk&Ven_VMware&Prod_Virtual_disk
|- 00000
I'm able to determine the vendor folder as well as the disk folders under the root of HKLM:\SYSTEM\CurrentControlSet\Enum\SCSI:
- hosts: some_host
tasks:
- name: Get vendor folders
win_reg_stat:
path: HKLM:\SYSTEM\CurrentControlSet\Enum\SCSI
register: vendors
- name: Get disk folders
win_reg_stat:
path: "HKLM:\\SYSTEM\\CurrentControlSet\\Enum\\SCSI\\{{ item }}"
with_items:
- "{{ vendors.sub_keys }}"
register: disks
- debug:
var: disks.results
The output looks like this:
ok: [some_host] => {
"disks.results": [
{
"ansible_loop_var": "item",
"changed": false,
"exists": true,
"failed": false,
"item": "CdRom&Ven_QEMU&Prod_QEMU_DVD-ROM",
"properties": {},
"sub_keys": [
"000001"
]
},
{
"ansible_loop_var": "item",
"changed": false,
"exists": true,
"failed": false,
"item": "Disk&Ven_QEMU&Prod_QEMU_HARDDISK",
"properties": {},
"sub_keys": [
"000000",
"000001"
]
},
{
"ansible_loop_var": "item",
"changed": false,
"exists": true,
"failed": false,
"item": "Disk&Ven_VMware&Prod_Virtual_disk",
"properties": {},
"sub_keys": [
"000000"
]
}
]
}
I'm a bit stuck right now. I'm trying to get a dictionary or list for iterating through all those disk folders. Something like that:
Disk&Ven_QEMU&Prod_QEMU_HARDDISK: 000000
Disk&Ven_QEMU&Prod_QEMU_HARDDISK: 000001
Disk&Ven_VMware&Prod_Virtual_disk: 000000
Is there a way to accomplish that?
Thanks and regards
Erik

Answer 1

For example
- set_fact:
my_list: "{{ my_list|default([]) + [{item.0.item:item.1}] }}"
with_subelements:
- "{{ disks.results }}"
- sub_keys
gives
my_list:
- CdRom&Ven_QEMU&Prod_QEMU_DVD-ROM: '000001'
- Disk&Ven_QEMU&Prod_QEMU_HARDDISK: '000000'
- Disk&Ven_QEMU&Prod_QEMU_HARDDISK: '000001'
- Disk&Ven_VMware&Prod_Virtual_disk: '000000'
It's not possible to create a dictionary because, in a dictionary, the keys must be unique.

I want to share my final solution with you. Thanks to Vladimir for the help.
- name: Get vendors
win_reg_stat:
path: HKLM:\SYSTEM\CurrentControlSet\Enum\SCSI
register: os_vendors
- name: Get vendors subfolders
win_reg_stat:
path: "HKLM:\\SYSTEM\\CurrentControlSet\\Enum\\SCSI\\{{ item }}"
loop: "{{ os_vendors.sub_keys }}"
register: os_subfolders
- name: Build registry pathes with vendors and disks
set_fact:
os_regpath_dict: "{{ os_regpath_dict | default({}) | combine ({item.item : item.sub_keys })}}"
loop: "{{ os_subfolders.results }}"
- name: Get disk folders
win_reg_stat:
path: "HKLM:\\SYSTEM\\CurrentControlSet\\Enum\\SCSI\\{{ item.0.key }}\\{{ item.1 }}\\Device Parameters\\Partmgr"
name: "Attributes"
loop: "{{ os_regpath_dict | dict2items | subelements('value') }}"
when: "'Disk' in item.0.key"
register: os_disks
- name: Set value of entry Attributes to 0
win_regedit:
path: "HKLM:\\SYSTEM\\CurrentControlSet\\Enum\\SCSI\\{{ item.item.0.key }}\\{{ item.item.1 }}\\Device Parameters\\Partmgr"
name: Attributes
data: 0
type: dword
loop: "{{ os_disks.results }}"
when: item.value is defined
