Hey team, I was looking to migrate my team over to the new

deployments ( old projects )

thingy, we store our docker images in ecr to run on ecs (AWS) and use git storage in github. I noticed on prefect-aws that the steps required for the build of the

prefect.yaml

doesnt have anything yet for a

build_docker_image

from ecs. Am I missing something or can I use a vanilla

- prefect_docker.deployments.steps.build_docker_image:

and reference a ecr image and it will handle it?

Hey @Ben Muller the support team will jump on this when they are online. cc @Emil Christensen

@Ben Muller Great question! So the

build_docker_image

step should work with any remote image repository, including ECR. In order to do it, you need to: 1. Use the full ECR name in your image name for the build step (e.g.

$AWS_ACCOUNT_ID.dkr.ecr.$<http://REGION.amazonaws.com/custom-flow-image|REGION.amazonaws.com/custom-flow-image>

) 2. Use the

push_docker_image

step (example here) 3. Be authenticated with ECR… this part is a bit trickier, and depends on how you have auth set up and such. Here’s an end-to-end example that I’m working on incorporating into the docs. The main mechanic to keep in mind is that it’s all based on the name of the image.
