Ansible with VMWare to create Dictionary using Ansible - ansible

Question

I am trying to create a dictionary with lists of items for a VMWare details collection. I was able to create the list individually. But not sure how to merge this.
- name: Gather DC info
community.vmware.vmware_datacenter_info:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
validate_certs: false
register: datacenter_infor
- name: Set DC_name variable
set_fact:
# dc_name: "{{ item.name }}"
dc_name: >-
{{ (dc_name | default([]))
+ [item.name]
}}
loop: "{{ datacenter_infor.datacenter_info }}"
- name: Gather cluster info
vmware_cluster_info:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
validate_certs: false
datacenter: "{{ item }}"
register: cluster_info
loop: "{{ dc_name }}"
- name: Set Host_name variable
set_fact:
host_name_list: >-
{{ (host_name_list | default([]))
+ data
}}
vars:
data: "{{ item.clusters.values() }}"
loop: "{{ cluster_info.results }}"
This will result in below output:
TASK [Set Host_name variable] *********************************************************************************************************************************************************************************************
ok: [localhost] => (item={'changed': False, 'clusters': {'PQR-CLU01': {'hosts': [{'name': 'PQR-cn0001.myhost.com', 'folder': '/PQR/host/PQR-CLU01'}, {'name': 'PQR-cn0002.myhost.com', 'folder': '/PQR/host/PQR-CLU01'}})
ok: [localhost] => (item={'changed': False, 'clusters': {'ABC-CLU01': {'hosts': [{'name': 'ABC-cn0002.myhost.com', 'folder': '/ABC/host/ABC-CLU01'}, {'name': 'ABC-cn0001.myhost.com', 'folder': '/ABC/host/ABC-CLU01'}})
How can I create a dictionary with above items like using ansible:
{'PQR-CLU01': ['PQR-cn0001.myhost.com','PQR-cn0002.myhost.com'],'ABC-CLU01':['ABC-cn0002.myhost.com','ABC-cn0001.myhost.com']

Answer 1

Given the data
cluster_info:
results:
- changed: false
clusters:
PQR-CLU01:
hosts:
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0001.myhost.com
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0002.myhost.com
- changed: false
clusters:
ABC-CLU01:
hosts:
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0002.myhost.com
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0001.myhost.com
Q: "Create dictionary (below)."
cluster_dict:
ABC-CLU01:
- ABC-cn0002.myhost.com
- ABC-cn0001.myhost.com
PQR-CLU01:
- PQR-cn0001.myhost.com
- PQR-cn0002.myhost.com
A: Create the list of clusters
cluster_list: "{{ cluster_info.results|
map(attribute='clusters')|
map('dict2items')|
flatten }}"
gives
cluster_list:
- key: PQR-CLU01
value:
hosts:
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0001.myhost.com
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0002.myhost.com
- key: ABC-CLU01
value:
hosts:
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0002.myhost.com
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0001.myhost.com
Create a list of keys
cluster_keys: "{{ cluster_list|
map(attribute='key')|
list }}"
gives
cluster_keys:
- PQR-CLU01
- ABC-CLU01
Create a list of values
cluster_vals: "{{ cluster_list|
map(attribute='value.hosts')|
map('map', attribute='name')|
list }}"
gives
cluster_vals:
- - PQR-cn0001.myhost.com
- PQR-cn0002.myhost.com
- - ABC-cn0002.myhost.com
- ABC-cn0001.myhost.com
Crate the dictionary
cluster_dict: "{{ dict(cluster_keys|zip(cluster_vals)) }}"
gives
cluster_dict:
ABC-CLU01:
- ABC-cn0002.myhost.com
- ABC-cn0001.myhost.com
PQR-CLU01:
- PQR-cn0001.myhost.com
- PQR-cn0002.myhost.com
