Notes
-----

.. note::
   - For the type of options ``data`` and ``criteria`` refer to the individual ``validate`` plugin documentation that is represented in the value of ``engine`` option.
   - For additional plugin configuration options refer to the individual ``validate`` plugin documentation that is represented by the value of ``engine`` option.
   - The plugin configuration option can be either passed as *key=value* pairs within filter plugin or environment variables.
   - The precedence of the ``validate`` plugin configurable option is the variable passed within filter plugin as *key=value* pairs followed by the environment variables.



Examples
--------

.. code-block:: yaml

    - name: set facts for data and criteria
      ansible.builtin.set_fact:
        data: "{{ lookup('ansible.builtin.file', './validate/data/show_interfaces_iosxr.json')}}"
        criteria: "{{ lookup('ansible.builtin.file', './validate/criteria/jsonschema/show_interfaces_iosxr.json')}}"

    - name: validate data in json format using jsonschema by passing plugin configuration variable as key/value pairs
      ansible.builtin.set_fact:
        data_validilty: "{{ data|ansible.utils.validate(criteria, engine='ansible.utils.jsonschema', draft='draft7') }}"



Return Values
-------------
