<p>I am using airflow on Kubernetes, with git-sync option for DAGS deployment. When there is a new DAGs pushed to our git repo, it airflow is not updating new DAGs until we restart scheduler pod. is there any other way to update the DAGs without restarting scheduler pod?</p>

<p>resolved this issue using git-sync sidecar container.</p>

<p>there is an  <code>extraContainers:</code> option in values.yaml file. we can add kubernetes git-sync as a sidecar container to continuously sync from git.</p>

<pre><code>extraContainers: 
  ## Additional containers to run alongside the Scheduler, Worker and Web pods
  ## This could, for example, be used to run a sidecar that syncs DAGs from object storage.
