Using additional containers
===========================

Sidecar Containers
------------------

If you want to deploy your own sidecar container, you can add it through the ``extraContainers`` parameter.
You can define different containers for the scheduler, webserver and worker pods.

For example, sidecars that sync DAGs from object storage.

.. code-block:: yaml

  scheduler:
    extraContainers:
      - name: s3-sync
        image: my-company/s3-sync:latest
        imagePullPolicy: Always
  workers:
    extraContainers:
      - name: s3-sync
        image: my-company/s3-sync:latest
        imagePullPolicy: Always

.. note::

   If you use ``workers.extraContainers`` with ``KubernetesExecutor``, you are responsible for signaling
   sidecars to exit when the main container finishes so Airflow can continue the worker shutdown process!


Init Containers
---------------

You can also deploy extra init containers through the ``extraInitContainers`` parameter.
You can define different containers for the scheduler, webserver and worker pods.

For example, an init container that just says hello:

.. code-block:: yaml

  scheduler:
    extraInitContainers:
      - name: hello
        image: debian
        args:
          - echo
          - hello
