@Marvin Do you perchance have example code for running tasks on ECS EC2 instead of ECS Fargate? This is for Prefect 2.x

Yes, running tasks on ECS EC2 instead of ECS Fargate is possible with Prefect 2.x. Here’s a guide to set this up. 1. Prerequisites: - An AWS account with permissions to create ECS services and IAM roles. - AWS CLI installed on your local machine. - An ECS Cluster to host both the worker and the flow runs it submits. You can use the default cluster or create your own. - A VPC configured for your ECS tasks. You can use the default VPC. - Prefect Cloud account or Prefect self-managed instance. 2. Set Up an ECS Work Pool: First, create an ECS work pool that the worker will pull work from. Using the CLI:

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

3. Configure ECS Task for EC2: When creating your ECS cluster and tasks, specify EC2 as the capacity provider. Here is an example of how you can configure your tasks to use EC2:

python
   from prefect_aws.ecs import ECSTask, AwsCredentials

   aws_credentials = AwsCredentials(
       aws_access_key_id="your_access_key_id",
       aws_secret_access_key="your_secret_access_key"
   )

   ecs_task = ECSTask(
       command=["python", "-c", "print('hello from an ECS EC2 task!')"],
       cluster="your_ecs_cluster_name",
       task_definition="your_task_definition",
       aws_credentials=aws_credentials,
       launch_type="EC2"  # Specify "EC2" here to use EC2 instead of Fargate
   )

   ecs_task.run()

4. Run the Task: Execute the task with the desired settings:

python
   if __name__ == "__main__":
       deploy_flow()

For a more detailed setup, refer to the Prefect documentation on ECS Integration. This guide outlines the steps in detail, including setting up the ECS work pool, configuring your cluster, and running tasks. Hope this helps you get started with running tasks on ECS EC2 with Prefect 2.x!

I'm not using ECSTask directly. Am I correct in surmising that if a Prefect worker is running in an ec2 ecs cluster, it will start tasks as ec2? Whereas if the worker is running in a fargate ecs cluster it will start tasks as Fargate?
