hostvars for localhost (Ansible master) only grabbing a few facts

I have this line in my playbook:

- debug: msg="{{ hostvars['127.0.0.1'] }}"

and for some reason it only grabs a handful of facts, primarily around setup of the master.

- hosts: mfg-pc:master
  become: yes
  become_method: sudo
  gather_facts: True
  tasks:
    - debug: msg="{{ hostvars['127.0.0.1'] }}"

An example of the facts gathered:

{
    "msg": {
        "ansible_check_mode": false,
        "ansible_connection": "local",
        "ansible_python_interpreter": "/usr/bin/python",
        "ansible_version": {
            "full": "2.2.0.0",
            "major": 2,
            "minor": 2,
            "revision": 0,
            "string": "2.2.0.0"
        },
        "group_names": [
            "ungrouped"
        ],
        "groups": {
            "all": [

Unfortunately, it doesn't grab the full list of variables that I get with:

ansible -m setup 127.0.0.1

I need the full list of facts as I'm trying to utilize the host (Ansible master) time to time-stamp a file I generate. This behavior seems inconsistent with another machine I was running it on, and I can't for the life of me determine why. Any guidance would be appreciated.

You don't gather facts from localhost in your playbook so you shouldn't expect Ansible to have them.

You must add a play which will execute setup (implicitly) against your localhost, for example:

---
- hosts: localhost
  connection: local

- hosts: mfg-pc:master
  become: yes
  become_method: sudo
  gather_facts: True
  tasks:
    - debug: msg="{{ hostvars['127.0.0.1'] }}"

Check parameter gather_subset into your configuration file ansible.cfg. To returns all facts it must be set to all:

gather_subset = all

If needed, to localize your configuration file ansible.cfg, type:

ansible --version

It must returns a line like this :

config file = /home/.../ansible.cfg
