Setting resources for containers

It is possible to set resources <https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/>__ for the containers managed by the chart. You can define different resources for various Airflow containers. By default the resources are not set.

.. note::

The Kubernetes scheduler can use resources to decide which node to place the pod on. Since a pod resource request/limit is the sum of the resource requests/limits for each container in the pod, it is advised to specify resources for each container in the pod.

Possible containers where resources can be configured include:

  • Main Airflow containers and their sidecars. You can add the resources for these containers through the following parameters:

    • workers.resources
    • workers.logGroomerSidecar.resources
    • workers.kerberosSidecar.resources
    • workers.kerberosInitContainer.resources
    • scheduler.resources
    • scheduler.logGroomerSidecar.resources
    • dags.gitSync.resources
    • apiServer.resources
    • webserver.resources
    • flower.resources
    • dagProcessor.resources
    • dagProcessor.logGroomerSidecar.resources
    • triggerer.resources
    • triggerer.logGroomerSidecar.resources
  • Containers used for Airflow Kubernetes jobs or cron jobs. You can add the resources for these containers through the following parameters:

    • cleanup.resources
    • createUserJob.resources
    • migrateDatabaseJob.resources
    • databaseCleanup.resources
  • Other containers that can be deployed by the chart. You can add the resources for these containers through the following parameters:

    • statsd.resources
    • pgbouncer.resources
    • pgbouncer.metricsExporterSidecar.resources
    • redis.resources

For example, specifying resources for worker Kerberos sidecar:

.. code-block:: yaml :caption: values.yaml

workers: kerberosSidecar: resources: limits: cpu: 200m memory: 256Mi requests: cpu: 100m memory: 128Mi
