        $(aws ecr describe-repositories |\
        jq -r '.repositories[].repositoryArn' |\
        sort -u |\
        awk -F ":" '{print $6}' |\
        sed 's/repository\///')
do
        echo "$1.dkr.ecr.eu-west-1.amazonaws.com/${repo}@$(aws ecr describe-images\
        --repository-name ${repo}\
        --query 'sort_by(imageDetails,& imagePushedAt)[-1].imageDigest' |\
        tr -d '"')"
done > latest-image-per-ecr-repo-${1}.list

The output will be written to a file named latest-image-per-ecr-repo-awsaccountid.list. An example of this output could be:

123456789123.dkr.ecr.eu-west-1.amazonaws.com/your-ecr-repository-name@sha256:fb839e843b5ea1081f4bdc5e2d493bee8cf8700458ffacc67c9a1e2130a6772a
...
...

With this you can do something like below to pull all the images to your machine.

#!/bin/bash -

for image in $(cat latest-image-per-ecr-repo-353131512553.list)
do
    docker pull $image
done

You will see that when you run docker images that none of the images are tagged. But you can 'fix' this by running these commands: docker images --format "docker image tag {{.ID}} {{.Repository}}:latest" > tag-images.sh chmod +x tag-images.sh ./tag-images.sh

Then they will all be tagged with latest on your machine.
