=============================================

This is a `FastAPI <https://docs.python.org/3/library/asyncio.html>`_
+ `Redis <https://redis.io/>`_
+ `Dependency Injector <https://python-dependency-injector.ets-labs.org/>`_ example application.

Run
---

Build the Docker image:

.. code-block:: bash

   docker-compose build

Run the docker-compose environment:

.. code-block:: bash

    docker-compose up

The output should be something like:

.. code-block::
