title: How to use airflow configuration file (airflow.cfg) when airflow run in container?
body: <p>I'm using Airflow that run in container as described <a href="https://airflow.apache.org/docs/apache-airflow/stable/start/docker.html" rel="nofollow noreferrer">here</a>. It seems that the configuration file <code>airflow.cfg</code> on the host have no impact on Airflow. I tried the solution <a href="https://stackoverflow.com/a/65189569/3026105">here</a> but it didn't help.
  The configuration fields I changed are:</p>
  <pre><code>default_timezone = system #(from utc)
  load_examples = False #(from True)
  base_url = http://localhost:8081 #(from 8080)
  default_ui_timezone = system #(from UTC)
  </code></pre>
  <p>I didn't see any impact on airflow eventhough I did <code>docker-compose down</code> and <code>docker-compose up</code></p>
