I'm afraid I couldn't find any specific examples of setting up Prefect server using Terraform on an ECS Fargate service. However, I did find some resources that might be helpful:
1.
Fargate Example - Terraform Registry: This is an example of how to use Terraform to set up an ECS Fargate service. You might be able to adapt this to set up a Prefect server.
2.
A guide to provisioning AWS ECS Fargate using Terraform: This guide explains how to provision an AWS ECS Fargate service using Terraform. Again, you might be able to adapt this to set up a Prefect server.
3.
Create and manage an AWS ECS cluster with Terraform: This blog post explains how to create and manage an AWS ECS cluster with Terraform. It might be useful as a reference.
I hope this helps. If you need more specific information, you might want to ask on the Prefect community forum or on a Terraform community forum.
