@Marvin How can I create a ecs task definition for a specific flow?

Based on the retrieved documents and issues, here's how you can create an ECS task definition for a specific flow using Prefect: 1. Configure ECS Worker: Ensure you use ECS workers as agents are deprecated. Refer to the ECS Work Pool for detailed guidance. 2. Define ECS Task: An ECS task definition serves as a blueprint for ECS tasks, describing Docker containers to run. Avoid frequent ECS task definition registrations to prevent hitting AWS rate limits. 3. Example Configuration: Here’s a sample setup to create an ECS task definition and run a flow:

python
   from prefect_aws import ECSTask
   from prefect import flow
   
   @flow
   def my_flow():
       print("Hello from ECS!")
   
   ecs_task = ECSTask(
       aws_credentials=aws_creds,  # Replace with your AWS credentials
       task_definition_arn='your-predefined-task-definition-arn',
       stream_output=True,
       cluster='your-ecs-cluster',
       launch_type='FARGATE'  # or 'FARGATE_SPOT'
   )
   
   ecs_task.save(name='my-ecs-task', overwrite=True)
   
   my_flow.deploy(
       name="my-ecs-deployment",
       infra_overrides={"task_definition_arn": 'your-predefined-task-definition-arn'}
   )

4. Predefined Task Definitions: If using predefined task definitions, ensure consistency to avoid re-registration. Example of using a predefined task:

python
   task_definition = 'arn:aws:ecs:<region>:<account_id>:task-definition/<definition-name>'
   
   ecs_task = ECSTask(
       task_definition_arn=task_definition,
       stream_output=True,
       cluster='your-ecs-cluster',
       launch_type='FARGATE',
   )

For more details, refer to the ECS integration docs and check related GitHub issues. If you face issues, make sure your ARN format is correct and verify ECS Task Definition registration doesn't exceed AWS rate limits.
