Ansible : Accessing value using template - ansible

Question

Here is my json :
{
"appId": "usecase-watchlist",
"instanceName": "usecase-watchlist-instance",
"node": "master",
"configuration": {
"videoSensorInstance": {
"node": "worker",
"configuration": {
"cameraSensor": 1
}
},
"faceDetectionInstance": {
"node": "worker",
"configuration": {
"cameraSensor": 1,
"database": {
"name": "facedetection_db",
"dbmsName": "mongodb",
"type": "mongodb",
"username": "fb719a05",
"password": "b5f64277"
}
}
},
"alerts-manager-instance": {
"node": "worker",
"configuration": {
"database": {
"name": "alerts_db",
"dbmsName": "mongodb",
"type": "mongodb",
"username": "fb719a05",
"password": "b5f64277"
}
}
}
}
}
I have a variable named : app_spec_contents where the content of this json is present.
Also, i have a dictionary app_instances which contains :
app_instances contains :
"app_instances": {
"alerts-manager": "alertsManagerInstance",
"video-sensor": "videoSensorInstance",...
}
Now i am writing below play that will create a map of given form :
#Get the configuration of instances one by one
- name: Get the configuration of instances one by one
set_fact:
app_configurations: "{{ app_configurations|default({}) | combine( { item.key:{ item.key + '_db_connection_string': app_spec_contents.configuration } } ) }}"
with_items : "{{ app_instances|dict2items }}"
I want a dict of below result :
{"alerts-manager" : {
"alerts-manager-instance_db_connection_string" :
"mongodb://fb719a05:b5f64277#172.17.0.2:27017/alerts_db",
"name":"alerts_db"
},
... } ---> for every item in dict if database is there, like in one instance.
Also, a when condition is to be written if the instance which is present in app_spec_contents.{{ item.value }} has configuration.database in it.
Kindly Help.

This has been resolved :
Below is the correct yaml :
- name: Get the configuration of instances one by one
set_fact:
app_configurations: "{{ app_configurations|default({}) | combine( { item.key:{ item.key + '_db_connection_string': app_spec_contents.configuration[item.value].configuration.database.dbmsName + '://' + app_spec_contents.configuration[item.value].configuration.database.username + ':' + app_spec_contents.configuration[item.value].configuration.database.password + '#172.17.0.2:27017/' + app_spec_contents.configuration[item.value].configuration.database.name , item.key + '_db_name' : app_spec_contents.configuration[item.value].configuration.database.name } } ) }}"
when: app_spec_contents.configuration[item.value].configuration.database is defined and app_spec_contents.configuration[item.value].configuration.database.dbmsName=="mongodb"
with_items : "{{ app_instances|dict2items }}"
