What is the KubernetesPodOperator in Airflow?

The KubernetesPodOperator runs any command inside a Docker container launched as a Kubernetes pod. It is independent of the executor type — even with CeleryExecutor you can use KubernetesPodOperator to run specific tasks in isolated pods.

from airflow.providers.cncf.kubernetes.operators.pod import KubernetesPodOperator

run_etl = KubernetesPodOperator(
    task_id='run_etl',
    name='etl-pod',
    namespace='airflow',
    image='myrepo/etl:latest',
    cmds=['python', 'etl.py'],
    arguments=['--date', '{{ ds }}'],
    get_logs=True,
    is_delete_operator_pod=True
)

This is useful for tasks that need specific dependencies, GPU access, or custom environments not available in the standard worker image.
