| 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 k8s Containers. By default the resources are not set. |
| |
| .. note:: |
| The k8s 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`` |
| * ``scheduler.resources`` |
| * ``scheduler.logGroomerSidecar.resources`` |
| * ``dags.gitSync.resources`` |
| * ``webserver.resources`` |
| * ``flower.resources`` |
| * ``triggerer.resources`` |
| |
| * Containers used for Airflow k8s jobs or cron jobs. You can add the resources for these Containers through the following parameters: |
| |
| * ``cleanup.resources`` |
| * ``createUserJob.resources`` |
| * ``migrateDatabaseJob.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 |
| |
| workers: |
| kerberosSidecar: |
| resources: |
| limits: |
| cpu: 200m |
| memory: 256Mi |
| requests: |
| cpu: 100m |
| memory: 128Mi |
