# Plugin Filter Configuration

Ansible 2.5 adds the ability for a site administrator to blacklist modules that they do not want to be available to Ansible. This is configured via a yaml configuration file (by default, `/etc/ansible/plugin_filters.yml`). Use `plugin_filters_cfg` configuration in `defaults` section to change this configuration file path. The format of the file is:

    ---
    filter_version: '1.0'
    module_blacklist:
      # Deprecated
      - docker
      # We only allow pip, not easy_install
      - easy_install

The file contains two fields:

- a version so that it will be possible to update the format while keeping backwards compatibility in the future. The present version should be the string, `"1.0"`
- a list of modules to blacklist. Any module listed here will not be found by Ansible when it searches for a module to invoke for a task.

Note

The `stat` module is required for Ansible to run. So, please make sure you do not add this module in a blacklist modules list.
