===============================================
Use python-tempestconf with a profile.yaml file
===============================================

A ``profile.yaml`` is helpful mainly in jobs running on different versions of
OpenStack, because arguments for ``python-tempestconf`` may differ in each
OpenStack version. Using the ``--profile`` argument those jobs can use
a ``profile.yaml`` file for each OpenStack version which makes the code of
those jobs much clearer and more readable, as for example they contain less if
else statements, ...

.. note::

    Apart from ``--deployer-input`` config file which specifies content of
    a tempest.conf, ``profile.yaml`` file defines arguments which are passed
    to ``python-tempestconf``, see `CLI documentation`_.

    .. _CLI documentation: ../cli/cli_options.html

.. warning::

    If this argument is used, other arguments cannot be defined, it means,
    user uses either CLI arguments or profile.yaml file.

.. note::

    The generated sample of a ``profile.yaml`` file contains all
    ``python-tempestconf`` arguments set to their default values. That means,
    that you can **remove arguments you didn't modify** to keep the file simple
    and more readable.


``python-tempestconf`` accepts both of the following inputs, so you can use
what suits you better, either strings or lists:

.. code-block:: yaml

    create: True
    out: ./etc/tempest.conf
    deployer-input: ./deploy.txt
    no-default-deployer: False
    overrides:
      identity.username: my_override
      identity.password: my_password
      network-feature-enabled.api_extensions: all
      volume-feature-enabled.api_extensions: dvr,mine
    remove:
      auth.identity: username
      network-feature-enabled.api_extensions: ''
      volume-feature-enabled.api_extensions: dvr,mine


.. code-block:: yaml

    create: True
    out: ./etc/tempest.conf
    deployer-input: ./deploy.txt
    no-default-deployer: False
    overrides:
      identity.username: my_override
      identity.password:
        - my_password
      network-feature-enabled.api_extensions:
        - all
      volume-feature-enabled.api_extensions:
        - dvr
        - mine
    remove:
      auth.identity: username
      network-feature-enabled.api_extensions:
        - ''
      volume-feature-enabled.api_extensions:
        - dvr
        - mine


Using profile.yaml file
+++++++++++++++++++++++

After you've created your customized ``profile.yaml`` file, let's say in
``./etc/profile.yaml``, use it as follows:

.. code-block:: Bash

    $ discover-tempest-config --profile ./etc/profile.yaml
