To collect backing_datastore from the vmware_guest_disk_info module output - filter

Question

I'm using the below tasks in the playbook to find the backing datastore in the vmware but I tried various options, which is not helping to gather the backing_datastore name, kindly suggest how to fetch:
- name: Take Snapshot
hosts: patching
serial: 1
vars_files:
- 1credentials.yml
tasks:
- name: Gather data of the registered virtual machines
community.vmware.vmware_vm_info:
hostname: '{{ vcenter_hostname }}'
username: '{{ vcenter_username }}'
password: '{{ vcenter_password }}'
vm_type: vm
validate_certs: no
delegate_to: localhost
register: vminfo
- debug:
msg: "{{ item.datacenter }}"
loop: "{{ vminfo.virtual_machines}}"
when: item.ip_address == inventory_hostname
- name: Gather Disk facts for the server - {{ inventory_hostname }}
vmware_guest_disk_info:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
datacenter: "{{ item.datacenter }}"
uuid: "{{ item.uuid }}"
validate_certs: False
delegate_to: localhost
register: disk_fact
loop: "{{ vminfo.virtual_machines }}"
when: item.ip_address == inventory_hostname
- debug:
msg: "{{ item.backing_datastore }}"
loop: "{{ disk_fact }}"
The raw output of the registered variable disk_fact is mentioned below:

Kindly suggest how can I fetch the backing_datastore from the above mentioned output.

Answer 1

The result is a list because there might be more items with the attribute backing_datastore. For example,
backing_datastores: "{{ disk_fact.results|json_query(_query) }}"
_query: '[].guest_disk_info[].*.backing_datastore'
gives
backing_datastores:
- - ENV04
If you want the first one
backing_datastore: "{{ backing_datastores|flatten|first }}"
gives
backing_datastore: ENV04
If you want to iterate results
- debug:
msg: "{{ item.guest_disk_info['0'].backing_datastore }}"
loop: "{{ disk_fact.results }}"
loop_control:
label: "{{ item.item.ip_address }}"
when: not item.skipped|d(false)
gives the attribute backing_datastore of the disk "0"
TASK [debug] **************************************************
skipping: [localhost] => (item=172.17.92.43)
ok: [localhost] => (item=172.17.92.62) =>
msg: ENV04
If you want to get the list of attributes backing_datastore of all disks use json_query in the loop
- debug:
msg: "{{ item.guest_disk_info|json_query('*.backing_datastore') }}"
loop: "{{ disk_fact.results }}"
loop_control:
label: "{{ item.item.ip_address }}"
when: not item.skipped|d(false)
gives
TASK [debug] **************************************************
skipping: [localhost] => (item=172.17.92.43)
ok: [localhost] => (item=172.17.92.62) =>
msg:

Example of a complete playbook for testing

backing_datastore: "{{ backing_datastores|flatten|first }}"
tasks:
