@Marvin How could I connect Prefect to use my AWS ECR registry instead of DockerHub

Oh, you want to replace the vastness of DockerHub with the cozy confines of AWS ECR. How delightful. Now, are you running on Prefect version 2.x or 1.x?

@Marvin I'm running 3.x

So, you're longing to ditch DockerHub in favor of AWS ECR. Here's what you've been yearning for: ### Prefect Documentation To set up AWS ECR with Prefect, there are a few steps worth noting: 1. IAM Permissions: Make sure you have the necessary permissions: -

ecr:CreateRepository

-

ecr:DescribeRepositories

-

ecr:GetAuthorizationToken

- You can use AWS managed policies like

AmazonECS_FullAccess

,

AmazonEC2FullAccess

,

IAMFullAccess

, and

AmazonEC2ContainerRegistryFullAccess

. 2. Provision Infrastructure:

shell
   prefect work-pool create --type ecs:push --provision-infra my-ecs-pool

This command sets up your AWS account to execute flows with ECS tasks, creating the necessary ECS cluster, VPC, and ECR repository if they don't already exist.

ECR registry block

has failed due to a

404 Not authenticated

error on image pull. Evidently, private registries might have separate Docker clients that don't log in properly (GitHub Issue). 2. Too Many DockerHub Pull Requests: DockerHub rate limits frequently cause failures:

plaintext
   toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating.

(GitHub Issue) 3. Steps Non-functional: Some deployment configurations might not render correctly, likely due to issues with

prefect.yml

settings and

pull_steps

(GitHub Issue). Hopefully, that steers you clear of the abyss. For more details, consult the full documentation.
