- class airflow.providers.amazon.aws.triggers.ecs.ClusterActiveTrigger(cluster_arn, waiter_delay, waiter_max_attempts, aws_conn_id, region_name=None, **kwargs)[source]¶
Bases:
airflow.providers.amazon.aws.triggers.base.AwsBaseWaiterTrigger
Polls the status of a cluster until it’s active.
- Parameters
cluster_arn (str) – ARN of the cluster to watch.
waiter_delay (int) – The amount of time in seconds to wait between attempts.
waiter_max_attempts (int) – The number of times to ping for status. Will fail after that many unsuccessful attempts.
aws_conn_id (str | None) – The Airflow connection used for AWS credentials.
region_name (str | None) – The AWS region where the cluster is located.
- class airflow.providers.amazon.aws.triggers.ecs.ClusterInactiveTrigger(cluster_arn, waiter_delay, waiter_max_attempts, aws_conn_id, region_name=None, **kwargs)[source]¶
Bases:
airflow.providers.amazon.aws.triggers.base.AwsBaseWaiterTrigger
Polls the status of a cluster until it’s inactive.
- Parameters
cluster_arn (str) – ARN of the cluster to watch.
waiter_delay (int) – The amount of time in seconds to wait between attempts.
waiter_max_attempts (int) – The number of times to ping for status. Will fail after that many unsuccessful attempts.
aws_conn_id (str | None) – The Airflow connection used for AWS credentials.
region_name (str | None) – The AWS region where the cluster is located.
- class airflow.providers.amazon.aws.triggers.ecs.TaskDoneTrigger(cluster, task_arn, waiter_delay, waiter_max_attempts, aws_conn_id, region, log_group=None, log_stream=None)[source]¶
Bases:
airflow.triggers.base.BaseTrigger
Waits for an ECS task to be done, while eventually polling logs.
- Parameters
cluster (str) – short name or full ARN of the cluster where the task is running.
task_arn (str) – ARN of the task to watch.
waiter_delay (int) – The amount of time in seconds to wait between attempts.
waiter_max_attempts (int) – The number of times to ping for status. Will fail after that many unsuccessful attempts.
aws_conn_id (str | None) – The Airflow connection used for AWS credentials.
region (str | None) – The AWS region where the cluster is located.
- async run()[source]¶
Run the trigger in an asynchronous context.
The trigger should yield an Event whenever it wants to fire off an event, and return None if it is finished. Single-event triggers should thus yield and then immediately return.
If it yields, it is likely that it will be resumed very quickly, but it may not be (e.g. if the workload is being moved to another triggerer process, or a multi-event trigger was being used for a single-event task defer).
In either case, Trigger classes should assume they will be persisted, and then rely on cleanup() being called when they are no longer needed.
