| 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 |
