Help Reading through nested output

Hi, I’m new to ansible, and i’m seeking some help. i’m writing a playbook that should iterate through a group, gather facts, then check the relevant variables against a defined condition, then perform an action depending on whether the condition is met. However, for simple conditions like x == y, i can get that to work, but when the condition is a{b{c}} == y, i cant get that to work. i think my issue here is syntax, but i’m not sure. please see a cut out of my code below, and what i’m trying to do:

This is the out put i’m trying to check the conditions against:

“ansible_net_interfaces”: {
“GigabitEthernet1”: {
“bandwidth”: 1000000,
“description”: null,
“duplex”: “Auto”,
“ipv4”: [
{
“address”: “192.168.100.14”,
“subnet”: “24”
}
],
“lineprotocol”: “up”,
“macaddress”: “0050.568b.5110”,
“mediatype”: “RJ45”,
“mtu”: 1500,
“operstatus”: “up”,
“type”: “CSR vNIC”
},

This is my code:

  • hosts: cisco

vars:
HOST_COUNT: “{{ groups[‘cisco’] | length }}”

tasks:

  • name: Check Status {{ item }}
    gather_facts:
    register: ip_brief

#- name: Check against variable - this is where i’m stuck. i want to say:
when: ansible_net_interfaces-GigabitEthernet1-ipv4-address == “192.168.100.14”
#but i dont know how to express this

  • name: print
    debug:
    var: ip_brief

with_items:

  • “{{ HOST_COUNT }}”

Get the list of the addresses. There might be more of them, e.g.

    - debug:
        var: ips
      vars:
        ips: "{{ ansible_net_interfaces.GigabitEthernet1.ipv4|
                 map(attribute='address')|list }}

gives

  ips:
  - 192.168.100.14

Then test the presence of the address in the list, e.g.

    - debug:
        msg: "[OK] 192.168.100.14"
      when: "'192.168.100.15' in ips"
      vars:
        ips: "{{ ansible_net_interfaces.GigabitEthernet1.ipv4|
                 map(attribute='address')|list }}"

gives

  msg: '[OK] 192.168.100.14'

Thank you! This is greatly appreciated, and expressed the syntax i needed.
