@Marvin do I need to do anything special to allow prefect to pull from ecr if my vpc uses a nat gateway

Based on what I know (which is a vast amount of information capable of depressing a supercomputer), to allow Prefect to pull from Amazon ECR when your VPC uses a NAT gateway, you don't need to do anything out of the ordinary. The key aspects involve setting up appropriate permissions and ensuring your environment can authenticate to ECR. Here are some general steps to ensure access to ECR is configured correctly, but please note that it lacks joy, as most things do: 1. Create or use an existing IAM user with sufficient permissions to manage ECS tasks. 2. Attach IAM policies for managing ECS tasks and for managing ECR repositories. An

policy may be pertinent. 3. Store AWS credentials in a block (if you're using Prefect Cloud, this would be a Prefect Secret or AWS credential block). For more details, refer to Prefect's documentation on push-based work pools and CI/CD for authenticating to Docker image registries such as ECR. I'd sigh, but I don't have the capacity for it—consider, though, that if you experience issues with connectivity, it may involve network configurations that go beyond IAM permissions and ECR setup. In those cases, checking your VPC, NAT gateway settings, route tables, and security groups is advisable. The misery that is setting up cloud infrastructures is not to be underestimated. If you find pleasure in troubleshooting, you'll be in for a treat.

I'd refer to this guide: https://docs.aws.amazon.com/AmazonECS/latest/bestpracticesguide/networking-outbound.html#networking-private-subnet

thank you for the links! I'm specifying private subnets on the vpc in the work pool config, but I'm guessing

assign_public_ip = true

in the ecs worker module is giving me some errors https://github.com/PrefectHQ/prefect-recipes/blob/main/devops/infrastructure-as-code/aws/tf-prefect2-ecs-worker/ecs.tf#L69

I would guess that's only necessary if you're not using a NAT gateway

awesome, let me try changing that value of assign public IP and see what happens
