 1. **Persistent Volume**: If you have many concurrent tasks, you may want to use a storage class that supports [`ReadWriteMany`](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes) access mode.
-2. **Cloud credentials**: If you wish to run tasks on different clouds, you can configure cloud credentials in Kubernetes secrets and mount them in the Sky pod defined in the DAG. See [SkyPilot docs on setting up cloud credentials](https://skypilot.readthedocs.io/en/latest/getting-started/installation.html#cloud-account-setup) for more on how to configure credentials in the pod.

 3. **Logging**: All SkyPilot logs are written to container stdout, which is captured as task logs in Airflow and displayed in the UI. You can also write logs to a file and read them in subsequent tasks.
 4. **XComs for shared state**: Airflow also provides [XComs](https://airflow.apache.org/docs/apache-airflow/stable/concepts/xcoms.html) for cross-task communication. [`sky_k8s_example_xcoms.py`](sky_k8s_example_xcoms.py) demonstrates how to use XComs to share state between tasks.
