Parameters

  • family (str) – The family name of a task definition to create.

  • container_definitions (List[Dict]) – A list of container definitions in JSON format that describe the different containers that make up your task.

  • register_task_kwargs (Optional[Dict]) – Extra arguments for Register Task Definition.

class airflow.providers.amazon.aws.operators.ecs.EcsRunTaskOperator(*, task_definition, cluster, overrides, launch_type='EC2', capacity_provider_strategy=None, group=None, placement_constraints=None, placement_strategy=None, platform_version=None, network_configuration=None, tags=None, awslogs_group=None, awslogs_region=None, awslogs_stream_prefix=None, awslogs_fetch_interval=timedelta(seconds=30), propagate_tags=None, quota_retry=None, reattach=False, number_logs_exception=10, wait_for_completion=True, **kwargs)[source]

Bases: EcsBaseOperator

Parameters

  • task_definition (str) – the task definition name on Elastic Container Service

  • cluster (str) – the cluster name on Elastic Container Service

  • overrides (dict) – the same parameter that boto3 will receive (templated): https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/ecs.html#ECS.Client.run_task

  • aws_conn_id – connection id of AWS credentials / region name. If None, credential boto3 strategy will be used (http://boto3.readthedocs.io/en/latest/guide/configuration.html).

  • region_name – region name to use in AWS Hook. Override the region_name in connection (if provided)

  • launch_type (str) – the launch type on which to run your task (‘EC2’, ‘EXTERNAL’, or ‘FARGATE’)

  • capacity_provider_strategy (Optional[list]) – the capacity provider strategy to use for the task. When capacity_provider_strategy is specified, the launch_type parameter is omitted. If no capacity_provider_strategy or launch_type is specified, the default capacity provider strategy for the cluster is used.

  • group (Optional[str]) – the name of the task group associated with the task

  • placement_constraints (Optional[list]) – an array of placement constraint objects to use for the task

  • placement_strategy (Optional[list]) – an array of placement strategy objects to use for the task

  • platform_version (Optional[str]) – the platform version on which your task is running

  • network_configuration (Optional[dict]) – the network configuration for the task

  • tags (Optional[dict]) – a dictionary of tags in the form of {‘tagKey’: ‘tagValue’}.

  • awslogs_group (Optional[str]) – the CloudWatch group where your ECS container logs are stored. Only required if you want logs to be shown in the Airflow UI after your job has finished.

  • awslogs_region (Optional[str]) – the region in which your CloudWatch logs are stored. If None, this is the same as the region_name parameter. If that is also None, this is the default AWS region based on your connection settings.

  • awslogs_stream_prefix (Optional[str]) – the stream prefix that is used for the CloudWatch logs. This is usually based on some custom name combined with the name of the container. Only required if you want logs to be shown in the Airflow UI after your job has finished.

  • awslogs_fetch_interval (datetime.timedelta) – the interval that the ECS task log fetcher should wait in between each Cloudwatch logs fetches.

  • quota_retry (Optional[dict]) – Config if and how to retry the launch of a new ECS task, to handle transient errors.

  • reattach (bool) – If set to True, will check if the task previously launched by the task_instance is already running. If so, the operator will attach to it instead of starting a new task. This is to avoid relaunching a new task when the connection drops between Airflow and ECS while the task is running (when the Airflow worker is restarted for example).

  • number_logs_exception (int) – Number of lines from the last Cloudwatch logs to return in the AirflowException if an ECS task is stopped (to receive Airflow alerts with the logs of what failed in the code running in ECS).

  • wait_for_completion (bool) – If True, waits for creation of the cluster to complete. (default: True)

execute(context, session=None)[source]

Must overwrite in child classes.

on_kill()[source]

Override this method to cleanup subprocesses when a task instance gets killed. Any use of the threading, subprocess or multiprocessing module within an operator needs to be cleaned up or it will leave ghost processes behind.
