I can now explain what's happening and provide the solution. The issue is that the documentation you're following appears to have an error. Based on the GitHub issues and PRs I found, the correct work pool type for ECS push infrastructure is just

ecs

with the

:push

suffix. Here's the correct command you should use:

bash
prefect work-pool create --type ecs --provision-infra my-ecs-pool2

The error you're seeing is because

ecs:push

is not a valid work pool type. The available work pool types are: - azure-container-instance - cloud-run - cloud-run-v2 - docker - ecs - kubernetes - process - vertex-ai When you create an ECS work pool, it will automatically be configured as a push pool with the necessary infrastructure if you use the

--provision-infra

flag. The

--provision-infra

flag will: 1. Create an IAM user for managing ECS tasks 2. Create and attach an IAM policy for managing ECS tasks 3. Store generated AWS credentials in a block 4. Create an ECS cluster for running Prefect flows 5. Create a VPC with the necessary networking components for running ECS tasks After running the command, you should be able to deploy and run flows in the created work pool without additional configuration. Would you like me to help you with anything else regarding the ECS work pool setup?
