How to add something to ansible_facts?

Hi,
maybe I am being stupid here, but why doesn’t it work, that when I call the

set_fact

module, and then run the

setup

module, my newly set fact is not returned?
What else do I have to do?

You can start by providing an example playbook.

For example:

`

  • name: Get date
    command curl http://some-url
    register: my_date

  • name: Set fact
    set_fact:
    my_date_as_fact: my_date

  • name: Gather facts
    setup:
    register: {{ ansible_facts }}

  • name: Print facts
    debug: msg={{ ansible_facts }}

`

“my_date_as_fact” is not included in the output.

Hi there,

Try doing,

-name: Set fact
set_fact:
my_date_as_fact: my_date

That is what I have, it was a typo in my post.

This is what I have now, and it is still not working.

`

  • name: Get app version
    command: curl -H application/json localhost:8088/rs
    register: get_version
    ignore_errors: true

  • name: Set app version as fact
    set_fact:
    fact_app_version:
    app_version: “{{ ((get_version | default({‘stdout’:‘N/A’})).stdout | from_json).version }}”
    ignore_errors: true

  • name: Gather facts
    setup:
    register: ansible_facts

  • name: Send facts somewhere
    local_action:
    module: uri
    url: “{{ some_url }}”
    method: PUT
    body: “{{ ansible_facts | combine(fact_app_version) | to_json }}”
    status_code: 204
    body_format: json

`

The error is:

`
FAILED! => {“failed”: true, “msg”: “the field ‘args’ has an invalid value (), and could not be converted to an dict. Error was: No JSON object could be decoded\n\nThe error appears to have been in ‘update-facts.yml’: line 18, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Set app version as fact\n ^ here\n”}

`

I am fairly certain what I am trying to do should be rather simply, however the more I dig into it, the uglier it gets.
I want to add an optional fact to the dictionary of facts, and then send all facts somewhere.

What is the suggested approach do accomplish this?

This is what I have now, and it is still not working.
- name: Get app version
  command: curl -H application/json localhost:8088/rs
  register: get_version
  ignore_errors: true

- name: Set app version as fact
  set_fact:
    fact_app_version:
          app_version: "{{ ((get_version |
default({'stdout':'N/A'})).stdout | from_json).version }}"
  ignore_errors: true

- name: Gather facts
  setup:
  register: ansible_facts

Remove the register:, you don't need it.
If gather_facts is set to true you can remove the entire "Gather facts" task.

- name: Send facts somewhere
  local_action:
    module: uri
    url: "{{ some_url }}"
    method: PUT
    body: "{{ ansible_facts | combine(fact_app_version) | to_json }}"
    status_code: 204
    body_format: json

Change body to
body: "{{ hostvars[inventory_hostname] }}"

hostvars should contain all you need as it contains all your facts, variables and groups.

@Kai Stian Olstad

Thank you, the magic that is hostvars[inventory_hostname] was exactly what I was looking for!

However I do have another question:

Is there a way to easily filter this list to at least exclude the temporary variables that got introduced during the playbook run, for example from “register” ?
