Use container image from a separate account

[andrewdavey]

I'd like to push a docker image to a repository in Acccount1. Then use this for a Fargate service running in Account2 (test) and then Account3 (prod).

My thinking is it's nice to only build the image once and have a single repository to pull from.

Does this require manually creating the Repository, instead of using things like ContainerImage.fromAsset?

Can anyone link me to examples please?
