module: include_vars
short_description: Load variables from files, dynamically within a task.
description:
     - 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.
version_added: "1.4"
options:
  file:
    version_added: "2.2"
    description:
       - 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.
  dir:
    version_added: "2.2"
    description:
      - 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.
    default: null
  name:
    version_added: "2.2"
    description:
        - The name of a variable into which assign the included vars, if omitted (null) they will be made top level vars.
    default: null
  depth:
    version_added: "2.2"
    description:
      - By default, this module will 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.
    default: 0
  files_matching:
    version_added: "2.2"
    description:
      - Limit the variables that are loaded within any directory to this regular expression.
    default: null
  ignore_files:
    version_added: "2.2"
    description:
      - List of file names to ignore. The defaults can not be overridden, but can be extended.
