Create and Delete Alibaba Cloud OSS Buckets¶

Purpose¶

This example dag uses OSSCreateBucketOperator and OSSDeleteBucketOperator to create a new OSS bucket with a given bucket name then delete it.

Defining tasks¶

In the following code we create a new bucket and then delete the bucket.

tests/system/providers/alibaba/example_oss_bucket.py[source]

with DAG(
    dag_id=DAG_ID,
    start_date=datetime(2021, 1, 1),
    schedule=None,
    default_args={"bucket_name": "your bucket", "region": "your region"},
    max_active_runs=1,
    tags=["example"],
    catchup=False,
) as dag:
    create_bucket = OSSCreateBucketOperator(task_id="task1", region=REGION)

    delete_bucket = OSSDeleteBucketOperator(task_id="task2", region=REGION)

    create_bucket >> delete_bucket

    from tests.system.utils.watcher import watcher

    # This test needs watcher in order to properly mark success/failure
    # when "tearDown" task with trigger rule is part of the DAG
    list(dag.tasks) >> watcher()
