How to append JSON array with specific data - json

Question

I am trying to run :
- name: Describe config aggregator
shell: >
aws configservice describe-configuration-aggregators --configuration-aggregator-name test-config
register: config_ouput
below is the data generated.
{
"ConfigurationAggregators": [
{
"ConfigurationAggregatorName": "test-config",
"ConfigurationAggregatorArn": "arn:aws:config:us-east-1:4567:config-aggregator/config-aggregator-uw2o9pzf",
"AccountAggregationSources": [
{
"AccountIds": [
"895677"
],
"AllAwsRegions": true
}
],
"CreationTime": 1624454176.124,
"LastUpdatedTime": 1626426755.504
}
]
}
Now I want to append the accountIds above with any new account say 1234567 which should give me result such as
{
"ConfigurationAggregators": [
{
"ConfigurationAggregatorName": "test-config",
"ConfigurationAggregatorArn": "arn:aws:config:us-east-1:8778:config-aggregator/test-config-pzf",
"AccountAggregationSources": [
{
"AccountIds": [
"895677,1234567"
],
"AllAwsRegions": true
}
],
"CreationTime": 1624454176.124,
"LastUpdatedTime": 1626426755.504
}
]
}
I am trying to do is:
- name: Export results to JSON
set_fact:
config_ouput_json: "{{ config_ouput + [{"AccountIds": "1234567","AllAwsRegions": true}]}}"
but this doesn't work, please let me know the right syntax.

Basically you require bit of JSON manipulation to achieve your task.
Steps :
Store output of first command in some json file. In your case you can keep that as registered variable of ansible.
Get existing account_ids in some variable.
Create a list of new accounts as variables in ansible.
Iterate over new account_ids and add to existing account_ids.
Update the aws config command.
Sample Code :
- name: initial validation
hosts: localhost
connection: local
vars:
newAccountIds:
- "123456"
- "566544"
- "555445"
tasks:
- name: register json file
include_vars:
file: 'abc.json'
name: bundle
- name: set value
set_fact:
values: "{{ bundle['ConfigurationAggregators'][0]['AccountAggregationSources'][0]['AccountIds'] }}"
- set_fact:
values: "{{ (values | default([])) + [item] }}"
with_items: "{{ newAccountIds }}"
- debug:
msg: "{{ values }}"
- debug:
msg: '"aws configservice put-configuration-aggregator --configuration-aggregator-name test-config --account-aggregation-sources "[{"AccountIds": {{ values | to_json }},"AwsRegions": ["us-east-1"]}]\""'
Sample Output :
