how to get vlan id from vcenter using ansible - ansible

Question

I am trying to use below ansible module to get vlan_id information.
- name: Get all portgroups in dvswitch vDS
vmware_dvs_portgroup_find:
hostname: "{{ vsphere_host }}"
username: "{{ vcenter_user }}"
password: "{{ vcenter_password }}"
dvswitch: 'test-123' --- dvswitch
validate_certs: no
with_items: "{{ dvswitch_list }}"
register: test
- debug: msg="{{ test }}"
I am getting out in below format.
"results": [
{
"ansible_loop_var": "item",
"changed": false,
"dvs_portgroups": [
{
"dvswitch": "test-123",
"name": "DPortGroup2",
"pvlan": false,
"trunk": false,
"vlan_id": "220"
},
{
"dvswitch": "test-123",
"name": "PP1",
"pvlan": false,
"trunk": false,
"vlan_id": "465"
},
{
"dvswitch": "test-123",
"name": "PP2",
"pvlan": false,
"trunk": false,
"vlan_id": "685"
},
I am using below debug msg to get vlan_id but some how it does not work.
- debug: msg="{{ item.vlan_id }}"
with_items: "{{ test.results.dvs_portgroups }}"
ASK [role_vmware_datastore_size : debug] ********************************************************************************
fatal: [192.168.90.00]: FAILED! => {"msg": "'list object' has no attribute 'dvs_portgroups'"}

Answer 1

test.results is the list of results for each item of the with_items of the vmware_dvs_portgroup_find task. Therefore you have to iterate over this list before accessing a field of each element.
If you want to iterate over all the dvs_portgroups of all the results, you can do that:
- debug: msg="{{ item.vlan_id }}"
with_items: "{{ test.results | map(attribute='dvs_portgroups') | flatten | list }}"
map(attribute='dvs_portgroups') is transforming the list of results into a list of the dvs_portgroups of each result
| flatten is transforming the list of lists (the dvs_portgroups) into a list of all elements of each lists
| list is transforming an iterator back to a list that can be interpreted by with_items

Answer 2

above debug code is working fine. I am getting list of vlan_id. Just to add more details. I have 4 dvswich and getting vlan_id from all dvswtich. I want to make it format like each dvswitch name with there vlan_id.
test-123 -- dvswith name
220
221
222
test-456 -- dvswtich name
300
301
302
I am trying below way but its giving only one vlan_id from each dvswitch.
- name: Final VLAN Details
set_fact:
vlan_details: "{{ vlan_details | default([]) + [dict(name=item[0], size=item[1])] }}"
loop: "{{ dvswitch | zip(vlan_id) | list }}"
loop_control:
label: " "
