Asyncio Daemon + Dependency Injector Example
============================================

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

The example application is a daemon that monitors availability of web services.

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::

   Starting monitoring-daemon-asyncio_monitor_1 ... done
   Attaching to monitoring-daemon-asyncio_monitor_1

Test
----

This application comes with the unit tests.

To run the tests do:

.. code-block:: bash

   docker-compose run --rm monitor py.test monitoringdaemon/tests.py --cov=monitoringdaemon

The output should be something like:

.. code-block::
