Hi, I'm new to ansible and have installed ansible version 2.7 and I'm trying to understand how I can filter the output from the new bigip_device_facts module as bigip_facts are depreciated. I ha...

    The result from bigip_device_facts contains a list of dictionaries. It can be processed in a number of ways depending on the output you want, but here's a simple example how to print the output with debug:

      - bigip_device_facts:
      provider: "{{ provider_vars }}"
      gather_subset:
        - vlans
    register: gathered_facts

  - name: "Debug vlans"
    debug:
      msg: "VLAN {{ item.name }} has tag {{ item.tag }}"
    with_items: "{{ gathered_facts.vlans }}"

Hi all,

I came here with the same doubt. the answer given is good and works perfectly, but if the gather_subset item contains a special character, it doesn't work.

This produces an error:

  - bigip_device_facts:
      provider: "{{ provider_vars }}"
      gather_subset:
        - ltm-pools
    register: gathered_facts

  - name: "Debug vlans"
    debug:
      msg: "VLAN {{ item.name }} has tag {{ item.tag }}"
    with_items: "{{ gathered_facts.ltm-pools }}"

Output error:

 FAILED! => {"msg": "Unable to look up a name or access an attribute in template string ({{ bigip_device_facts.ltm-pools }}).\nMake sure your variable name does not contain invalid characters like '-': unsupported operand type(s) for -: 'StrictUndefined' and 'AnsibleUnicode'"}
        to retry, use: --limit @/opt/project/facts.retry

Any ideas? Thanks.
