Fetch values from json


I'm new here and new to ansible playbooks. I'm trying to grab all the IPs that our F5 GTM/DNS devices use for iquery (not important). I'm running this task in my playbook...

  tasks:
    - name: get gtm servers
      bigip_device_info:
        gather_subset: gtm-servers
        provider: "{{ providerA }}"
      register: out

Below is the output of two of the gtm-servers, there are many. There are two different types of gtm-servers, "product: bigip" and "product: generic-host". If it's a bigip, I need to grab the two IPs (10.1.1.1 and 10.1.1.2). If it's a generic-host, I don't need it.

    },

I've tried this...

- name: fetch server ips
  set_fact:
    server_ips: "{{ out.gtm_servers | json_query('[*].{name: name}') }}"

But of course it only grabs the first name in the list and not that nested addresses:name that contains the IPs. And I'm lost on only grabbing the bigip IPs and not the generic-host IPs. Very grateful for any help.


Solution

  • For example

        - set_fact:
            server_ips: "{{ gtm_servers|
                            json_query('[?product==`bigip`].addresses[].name') }}"
    

    gives

    server_ips:
      - 10.1.1.1
      - 10.1.1.2
