Question

Hi Prefect community We re using prefect cloud as backend Docker Storage which uses a local Dockerfile and the prefect docker agent which uses the local image created by that local Dockerfile We ve created an AWS ECR Repository to store the image and I d like to use that instead of the local one I had the impression that I could do that by removing Docker Storage s `dockerfile` argument and adding a `registry url=MY ECR URL` param but that doesn t work and if I keep both params it tries to push the image to the ECR repo which I don t want What s the right setup for this case

I found a helpful explanation of storage and run config in this thread <https prefect community slack com archives CL09KU1K7 p1612805566470200 thread ts=1612802267 457300 amp cid=CL09KU1K7> So going by this logic it should be possible to set the Storage object s source to my image hosted on the ECR Repository correct Is it that I m using the wrong Storage class But DockerStorage seems to be the only one to be able to handle flows inside a Docker container thinking face

Update on my problem in case anybody else has the same issue The registry url to pull an image needs to be given by using the `base image` param and not the `registry url` param E g ```flow storage = Docker base image= <http some aws ecr amazonaws com repo name latest|some aws ecr amazonaws com repo name latest> ```
