ansible.builtin.include_vars – Load variables from files, dynamically within a task

Note

This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name include_vars even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

New in version 1.4: of ansible.builtin

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.

Note

This module has a corresponding action plugin.

Parameters

Parameter Choices/Defaults Comments
depth
integer
added in 2.2 of ansible.builtin
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
added in 2.2 of ansible.builtin
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 / elements=string
added in 2.3 of ansible.builtin
Default:
["json", "yaml", "yml"]
List of file extensions to read when using dir.
file
path
added in 2.2 of ansible.builtin
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
added in 2.2 of ansible.builtin
Limit the files that are loaded within any directory to this regular expression.
free-form
string
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 / elements=string
added in 2.2 of ansible.builtin
List of file names to ignore.
ignore_unknown_extensions
boolean
added in 2.7 of ansible.builtin
    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
added in 2.2 of ansible.builtin
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.
