Copy docker image from one AWS ECR repo to another - amazon-web-services

Question

We want to copy a docker image from non-prod to prod ECR account. Is it possible without pulling, retaging and pushing it again.

Answer 1

No you have to run these commands
docker login OLD_REPO
docker pull OLD_REPO/IMAGE:TAG
docker tag OLD_REPO/IMAGE:TAG NEW_REPO/IMAGE:TAG
docker login NEW_REPO
docker push NEW_REPO/IMAGE:TAG

Answer 2

I have written this program in python to migrate all the images (or a specific image) from a repository to another region or to another account in a different region

Answer 3

Answer: No, you must pull, tag, and push.
I wrote a bash script for this today. You can specify the number of tagged images that will be copied.
