@Marvin Can you give me the base job template for ECS?

To create a base ECS job template for running Prefect flows, you need to follow these steps: 1. Create an ECS Task Role: This role should have permissions required by the ECS tasks, such as accessing S3 if your workflow involves it. 2. Attach Policies: Attach the

AmazonECSTaskExecutionRolePolicy

to your task execution role for permissions to pull images from ECR and publish logs to CloudWatch. 3. Create an ECS Worker Service: Launch an ECS service to host the worker. You'll need to create an ECS task definition specifying the necessary configurations. 4. Register the Task Definition: Use the AWS CLI to register your task definition. This step involves specifying the CPU and memory allocations, and configuring the Prefect API URL and API key. For detailed guidance, you can refer to the Prefect ECS Guide.

@Marvin Can you give me the base job template in json to use in terraform to create the worker pool in ECS?

To create a base job template in JSON for an ECS worker pool using Terraform, you'll need to define the task definition and associated settings. Below is a basic example you can use as a starting point:

json
{
  "family": "prefect-ecs-worker",
  "networkMode": "awsvpc",
  "containerDefinitions": [
    {
      "name": "prefect-worker",
      "image": "prefecthq/prefect:latest",
      "essential": true,
      "memory": 512,
      "cpu": 256,
      "environment": [
        {
          "name": "PREFECT_API_URL",
          "value": "<prefect-api-url>"
        },
        {
          "name": "PREFECT_API_KEY",
          "value": "<your-api-key>"
        }
      ],
      "logConfiguration": {
        "logDriver": "awslogs",
        "options": {
          "awslogs-group": "/ecs/prefect",
          "awslogs-region": "<your-region>",
          "awslogs-stream-prefix": "ecs"
        }
      }
    }
  ],
  "requiresCompatibilities": ["FARGATE"],
  "cpu": "256",
  "memory": "512",
  "executionRoleArn": "<ecs-task-role-arn>",
  "taskRoleArn": "<ecs-task-role-arn>"
}

### Key Points: - Environment Variables: Replace

<prefect-api-url>

and

<your-api-key>

with your Prefect API URL and API key, respectively. - Role ARNs: Replace

<ecs-task-role-arn>

with the ARN of the IAM role you created with necessary permissions. - Logging: Ensure the

awslogs

configuration matches your desired log group and region. For more detailed guidance, visit the Prefect ECS Guide.

@Marvin what about the "auto_deregister_task_definition" var?

The

auto_deregister_task_definition

variable is not explicitly mentioned in the Prefect ECS documentation or the excerpts I found. This variable might be part of a custom configuration or a specific Terraform module you're using for ECS. In general, the concept of auto deregistration would involve automatically deregistering ECS task definitions that are no longer in use. This is not a built-in feature of AWS ECS but could be implemented in custom scripts or modules to manage task definitions efficiently. For detailed and specific Terraform configurations, you might want to check the documentation or source code of the Terraform module you are using, as it might provide insights into how this variable is used or configured. If you're using a specific Terraform module for ECS, reviewing its documentation could be beneficial.
