Agent which deploys flow runs as ECS tasks.

Args:

  • agent_config_id (str, optional): An optional agent configuration ID that can be used to set configuration based on an agent from a backend API. If set all configuration values will be pulled from the backend agent configuration.
  • name (str, optional): An optional name to give this agent. Can also be set through the environment variable PREFECT__CLOUD__AGENT__NAME. Defaults to "agent".
  • labels (List[str], optional): A list of labels, which are arbitrary string identifiers used by Prefect Agents when polling for work.
  • env_vars (dict, optional): A dictionary of environment variables and values that will be set on each flow run that this agent submits for execution.
  • max_polls (int, optional): Maximum number of times the agent will poll Prefect Cloud for flow runs; defaults to infinite.
  • agent_address (str, optional): Address to serve internal api at. Currently this is just health checks for use by an orchestration layer. Leave blank for no api server (default).
  • no_cloud_logs (bool, optional): Disable logging to a Prefect backend for this agent and all deployed flow runs. Defaults to False.
  • task_definition_path (str, optional): Path to a task definition template to use when defining new tasks. If not provided, the default template will be used.
  • run_task_kwargs_path (str, optional): Path to a yaml file containing default kwargs to pass to ECS.client.run_task. May be a local path, or a remote path on e.g. s3.
  • aws_access_key_id (str, optional): AWS access key id for connecting the boto3 client. If not provided, will be loaded from your environment (via either the AWS_ACCESS_KEY_ID environment variable, or the ~/.aws/config file). See the boto3 credentials docs for more information.
  • aws_secret_access_key (str, optional): AWS secret access key for connecting the boto3 client. If not provided, will be loaded from your environment (via either the AWS_SECRET_ACCESS_KEY environment variable, or the ~/.aws/config file). See the boto3 credentials docs for more information.
  • aws_session_token (str, optional): AWS session key for connecting the boto3 client. If not provided, will be loaded from your environment (via either the AWS_SESSION_TOKEN environment variable, or the ~/.aws/config file). See the boto3 credentials docs for more information.
  • region_name (str, optional): AWS region name to launch ECS tasks in. If not provided, will be loaded from your environment (via either the AWS_DEFAULT_REGION environment variable, or the ~/.aws/config file). See the boto3 configuration docs for more information.
  • cluster (str, optional): The AWS cluster to use, defaults to "default" if not provided.
  • launch_type (str, optional): The launch type to use, either "FARGATE" (default) or "EC2".
  • task_role_arn (str, optional): The default task role ARN to use when registering ECS tasks created by this agent.
  • execution_role_arn (str, optional): The default execution role ARN to use when registering ECS tasks created by this agent.
  • botocore_config (dict, optional): Additional botocore configuration options to be passed to the boto3 client. See the boto3 configuration docs for more information.
