title: Deploying Code to Airflow without a Full Restart
body: <p>I have a celery apache-airflow setup with one worker node on an EC2 instance. For code deployment, the user triggers deployment, copying the code package to s3; some infra related script copies the code package from s3 onto the instance; the instance triggers a restart of ALL the airflow-related services.</p>
  
  <p>I want to make it so that whenever I need to modify the code, ideally any jobs that are currently running should still continue to run, without using a cluster setup. </p>
  
  <p>I'm thinking that maybe finding a way to restart the web server and scheduler without restarting the worker could solve this problem.</p>
