I'm trying find datasore of vm guest with ansible - ansible

Question

I'm trying to extract value of vm datastore with ansible snippet:
- name: Gather disk facts from virtual machine using name
vmware_guest_disk_facts:
hostname: "{{ vcenter_server }}"
username: "{{ vcenter_user }}"
password: "{{ vcenter_pass }}"
datacenter: "{{ datacenter }}"
validate_certs: no
name: "{{ item }}"
delegate_to: localhost
register: disk_facts
with_items: "{{ vm_list }}"
- name: Get disk info
debug:
var: disk_facts.results.guest_disk_facts.backing_datastore
Output:
[root#sysmgttl1 lvm]# ansible-playbook -i hosts vmfacts.yml -e vcenter_server=vmimgtpw002 -e vm_list=sndprfql8
PLAY [sndprfql8] ***********************************************************************************************************************************************************
TASK [Gathering Facts] *****************************************************************************************************************************************************
ok: [sndprfql8]
TASK [Gather disk facts from virtual machine using name] *******************************************************************************************************************
ok: [sndprfql8 -> localhost] => (item=sndprfql8)
TASK [Get disk info] *******************************************************************************************************************************************************
ok: [sndprfql8] => {
"disk_facts.results.guest_disk_facts.backing_datastore": "VARIABLE IS NOT DEFINED!"
}
PLAY RECAP *****************************************************************************************************************************************************************
sndprfql8 : ok=3 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
This is what my disk_facts looks like.
ok: [sndprfql8] => {
"disk_facts": {
"changed": false,
"msg": "All items completed",
"results": [
{
"ansible_loop_var": "item",

},

}
},
"item": "sndprfql8"
}
]
}
}

If this is really for a one shot use, the following should do:
- name: Get disk info
debug:
var: disk_facts.results[0].guest_disk_facts['0'].backing_datastore
If you goal is to get all values for a list of vms in the result possibly having several disks, the following will give you a flattened list (that you can de-duplicate with the unique filter if needed)
- debug:
msg: "{{ disk_facts | json_query('results[].guest_disk_facts.*[].backing_datastore') }}"
