I have some problems creating a loop that works for the following nested structures:
1st level:
DeviceList = [Device1, Device2, Device3, etc..]
2nd level: Each device is a dictionary structure as follows:
Device1 =
"description" : "string",
"Id": "Value",
"DeviceIPs": Dictionary
3rd level: DeviceIPs is a dictionary where the key is one of the IPs assigned to the device converted to a string.
"DeviceIPs" =
"IP1": "description": "string1", "interface": "eth0", "mask":"subnet_mask1" ,
"IP2": "description": "string2", "interface": "eth1", "mask":"subnet_mask2" ,
"IP3": "description": "string3", "interface": "eth2", "mask":"subnet_mask3" ,
etc..
Ideally, I need to create a loop for the the keys of "DeviceIPs" so:
"IP1"
"IP2"
"IP3"
possibly based on the inner value (for instance matching a when condition like interface == "eth1")
I have tried different ways but I really can't come out with anything that works.. any idea?

Hi Konstantin, I actually managed to make it work with json_query filter. My problem was to loop through the IPs used as keys in the DeviceIPs dict, given DeviceList. I changed the DeviceList to be a dictionary: DeviceDict and used json_query as follows: tasks: - debug: msg: "IP: item " with_items: " DeviceDict " This will loop through all the possible device records in DeviceDict and get the keys in DeviceIPs which are indeed the IPs. Thanks!

Try reorganizing your variables to loop over eth1. For example:
---
- name: Test
hosts: localhost
connection: local
gather_facts: False
vars:
- DeviceList:
- Device:
description: string
Id: Value1
DeviceIPs:
- eth0: "description": "string1", "ip": "value1", "mask":"subnet_mask1"
- eth1: "description": "string2", "ip": "value2", "mask":"subnet_mask2"
- eth2: "description": "string3", "ip": "value3", "mask":"subnet_mask3"
- Device:
description: string
Id: Value2
DeviceIPs:
- eth0: "description": "string1", "ip": "value1", "mask":"subnet_mask1"
- eth1: "description": "string2", "ip": "value2", "mask":"subnet_mask2"
- eth2: "description": "string3", "ip": "value3", "mask":"subnet_mask3"
tasks:
- debug: var=item.1.eth1.ip

- " DeviceList "

Hi Christina, Thanks for the advice but that structure does not really work for me becaue, in DeviceList, I need a device identifier (e.g. Device1, Device2, Device3, etc..) and not a fixed key value: "Device" and subelements does not work in that case..
