Mount Extra Persistent Volumes

Mount on CeleryExecutor Workers

You may use the workers.extraVolumeMounts and workers.extraVolumes values to mount persistent volumes on the airflow CeleryExecutor worker pods.

For example, to mount a Volume called worker-tmp at the /tmp directory of all CeleryExecutor worker pods:

workers:
  extraVolumeMounts:
    - name: worker-tmp
      mountPath: /tmp
      readOnly: false

  extraVolumes:
    - name: worker-tmp
      persistentVolumeClaim:
        claimName: worker-tmp

Mount on KubernetesExecutor Pod Template

You may use the airflow.kubernetesPodTemplate.extraVolumeMounts and airflow.kubernetesPodTemplate.extraVolumes values to mount persistent volumes on the airflow KubernetesExecutor pod template.

For example, to mount a Volume called worker-tmp at the /tmp directory of all KubernetesExecutor pod templates:

airflow:
  kubernetesPodTemplate:
    extraVolumeMounts:
      - name: worker-tmp
        mountPath: /tmp
        readOnly: false
  
    extraVolumes:
      - name: worker-tmp
        persistentVolumeClaim:
          claimName: worker-tmp
