# include_vars – Load variables from files, dynamically within a task

## Synopsis

- Loads YAML/JSON variables dynamically from a file or directory, recursively, during task runtime.
- If loading a directory, the files are sorted alphabetically before being loaded.
- This module is also supported for Windows targets.
- To assign included variables to a different host than `inventory_hostname`, use `delegate_to` and set `delegate_facts=yes`.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
depth integer | Default: 0 | When using `dir`, this module will, by default, recursively go through each sub directory and load up the variables. By explicitly setting the depth, this module will only go as deep as the depth.
dir path |  | The directory name from which the variables should be loaded. If the path is relative and the task is inside a role, it will look inside the role's vars/ subdirectory. If the path is relative and not inside a role, it will be parsed relative to the playbook.
extensions list | Default: ["json", "yaml", "yml"] | List of file extensions to read when using `dir`.
file path |  | The file name from which variables should be loaded. If the path is relative, it will look for the file in vars/ subdirectory of a role or relative to playbook.
files_matching string |  | Limit the files that are loaded within any directory to this regular expression.
free-form - |  | This module allows you to specify the 'file' option directly without any other options. There is no 'free-form' option, this is just an indicator, see example below.
ignore_files list |  | List of file names to ignore.
ignore_unknown_extensions boolean added in 2.7 | Choices: no ← yes | Ignore unknown file extensions within the directory. This allows users to specify a directory containing vars files that are intermingled with non-vars files extension types (e.g. a directory with a README in it and vars files).
name string |  | The name of a variable into which assign the included vars. If omitted (null) they will be made top level vars.

## Notes

Note

- This module is also supported for Windows targets.

## Examples

    - name: Include vars of stuff.yaml into the 'stuff' variable (2.2).

      when: x == 0

    - name: Load a variable file based on the OS type, or a default if not found. Using free-form to specify the file.
      include_vars: "{{ lookup('first_found', possible_files) }}"
      vars:
        possible_files:
          - "{{ ansible_distribution }}.yaml"
          - "{{ ansible_os_family }}.yaml"
          - default.yaml

    - name: Bare include (free-form)
      include_vars: myvars.yaml

      include_vars:
        dir: vars/all
        extensions:
            - json
            - jsn

    - name: Include all default extension files in vars/all and all nested directories and save the output in test. (2.2)
      include_vars:

    - name: Include default extension files in vars/services (2.2)
      include_vars:
        dir: vars/services
        depth: 1

    - name: Include only files matching bastion.yaml (2.2)
      include_vars:
        dir: vars
        files_matching: bastion.yaml

    - name: Include all .yaml files except bastion.yaml (2.3)
      include_vars:
        dir: vars
        ignore_files: [bastion.yaml]
        extensions: [yaml]

    - name: Ignore warnings raised for files with unknown extensions while loading (2.7)
      include_vars:
        dir: vars
        ignore_unknown_extensions: True

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
ansible_included_var_files list added in 2.4 | success | A list of files that were successfully included Sample: ['/path/to/file.json', '/path/to/file.yaml']
