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.celery.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
