include_vars - Load variables from files, dynamically within a task

New in version 1.4.

Synopsis

  • Loads variables from a YAML/JSON files dynamically from within a file or from a 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.

Parameters

Parameter Choices/Defaults Comments
depth
(added in 2.2)
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
(added in 2.2)
The directory name from which the 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.
extensions
(added in 2.3)
Default:
[u'yaml', u'yml', u'json']
List of file extensions to read when using dir.
file
(added in 2.2)
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
(added in 2.2)
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
(added in 2.2)
List of file names to ignore.
name
(added in 2.2)
The name of a variable into which assign the included vars. If omitted (null) they will be made top level vars.
