@Marvin How to setup prefect ecs work pool that uses EC2 Launch Type and elastic ec2 cluster?

To set up a Prefect ECS work pool with EC2 Launch Type and an elastic EC2 cluster, you can follow these detailed steps: Prerequisites: 1. An AWS account with permissions to create ECS services and IAM roles. 2. AWS CLI installed on your local machine. 3. An ECS Cluster to host both the worker and the flow runs it submits. 4. A VPC configured for your ECS tasks. 5. Prefect Cloud account or Prefect self-managed instance. Step-by-Step Guide: 1. Create an ECS Work Pool: - Use the CLI to create an ECS work pool:

shell
     prefect work-pool create --type ecs my-ecs-pool

2. Configure the ECS Work Pool: - Use EC2 as the capacity provider. If using the default, specify this in your pool settings. Ensure your pool configuration includes the ARN (Amazon Resource Name) for the ECS task. 3. Set Up Your ECS Cluster: - Follow the AWS ECS Guide to create a cluster if you don't have one. You can refer to this link: AWS ECS Cluster Setup Guide 4. Deploying a Simple Flow _(Example in Python)_:

python
    from prefect import flow, task

    @task(task_run_name="Adding {x} and {y}")  # you can template arguments into the task name!
    def add(x: int, y: int) -> int:
        """just a python function with a fancy hat on!"""
        return x + y

    @flow
    def my_flow():
        """tasks must be called in the flow to be executed (at this time)"""
        first_result = add(1, 2) 
        second_result = add(first_result, first_result)
        return add(first_result, second_result)

    if __name__ == "__main__":
        # run the flow
        my_flow()

@Marvin How to configure ECS task?

To configure an ECS task for use with Prefect, you need to understand the components involved and the necessary steps to set them up. Below is a concise guide: Concepts: - ECS Task Definition: Describes which Docker containers to run and the configurations of these containers. - ECS Task: Instances of a task definition that run within an ECS Cluster. Steps to Configure an ECS Task: 1. Create an ECS Task Definition: - Navigate to the ECS section in the AWS Management Console. - Go to "Task Definitions" and create a new task definition. - Choose EC2 as the launch type if you are not using Fargate. - Define the Docker containers that the task will run, specifying image, CPU, memory, and any IAM roles necessary. 2. Configure the ECS Cluster: - Ensure that your task definitions point to the correct Docker images and that these images are stored in an accessible Docker registry like ECR (Elastic Container Registry). 3. Create a Work Pool in Prefect: - Use the CLI to create an ECS work pool that the worker will use to pull tasks:

shell
     prefect work-pool create --type ecs my-ecs-pool

4. Set Up Prefect Worker to Use ECS Task: - Ensure that the worker within the ECS setup uses the correct task definition ARN when spinning up the ECS task. Example Flow Code: Here's an example of a basic Prefect flow that you can configure to run within your ECS task:

python
from prefect import flow, task

@task(task_run_name="Adding {x} and {y}")  # You can template arguments into the task name!
def add(x: int, y: int) -> int:
    """Basic addition task"""
    return x + y

@flow
def my_flow():
    """Placeholder for your tasks"""
    first_result = add(1, 2) 
    second_result = add(first_result, first_result)
    return add(first_result, second_result)

if __name__ == "__main__":
    # Run the flow
    my_flow()
