In Prefect 3.x, there are three distinct types of work pools, each designed for different deployment scenarios: 1. Managed Work Pools - Fully managed by Prefect - Automatically handle job submission and execution - Use Prefect-managed infrastructure - No worker process needed 2. Push Work Pools - Enable serverless deployments - Automatically submit runs to specified infrastructure - No worker process needed - Great for cloud-native deployments 3. Hybrid Work Pools - Require running a worker process - Submit runs to your own infrastructure - Provide maximum control and flexibility - Ideal for environments with specific security or infrastructure requirements Work pools serve as the bridge between Prefect's orchestration capabilities and your execution environment. They allow platform teams to establish standardized configurations and enforce infrastructure policies across deployments.

Based on the research and GitHub issues, here's how to associate infrastructure with Prefect deployments in Terraform: 1. Basic Terraform Configuration

hcl
resource "prefect_deployment" "my_deployment" {
  name          = "my-deployment"
  flow_path     = "/path/to/flow.py"
  entrypoint    = "flow.py:my_flow"
  work_pool_name = "my-work-pool"

  infrastructure = {
    type = "ecs"  # or "kubernetes", depending on your infrastructure
    env = {
      MY_ENV_VAR = "value"
    }
    # Infrastructure-specific settings follow
  }
}

2. For ECS-specific Configuration

hcl
resource "prefect_deployment" "ecs_deployment" {
  # ... basic configuration ...

  infrastructure = {
    type = "ecs"
    capacity_provider_strategy = [
      {
        capacity_provider = "your-capacity-provider"
        weight           = 1
        base            = 0
      }
    ]
    cluster       = "your-ecs-cluster"
    task_role_arn = "your-task-role-arn"
    # Other ECS-specific settings as needed
  }
}

Key considerations: 1. Work Pool Type Matters: - For ECS: Use either Push work pools (for Fargate) or Hybrid work pools (for EC2) - For GPU workloads: Must use Hybrid work pools with proper capacity provider strategy 2. Important Infrastructure Settings: - Specify environment variables using the

env

block - Include necessary IAM roles and permissions - Configure networking settings if required - Specify resource requirements (CPU, memory) 3. Best Practices: - Keep sensitive values in Terraform variables or secrets management - Use data sources to reference existing AWS resources - Consider using workspaces for different environments 4. Common Gotchas: - For ECS GPU workloads, you must use capacity provider strategy, not launch type - Ensure all referenced resources (clusters, roles, etc.) exist before deployment - Check that the specified image contains all necessary dependencies For more detailed information about managing Prefect deployments with Terraform, you can refer to the official blog post.
