How to add something to ansible_facts?

[thok...@gmail.com]

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?

[Alexander H. Laughlin]

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

Thanks

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?

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

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!

[thok...@gmail.com]

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" ?
