Python3.6 Rename and Push Docker Images into New Repository

Below python code changes the repository names:

client = docker.from_env()
docker_api = docker.APIClient()
images = client.images.list()
for image in images:
    try:
        if image.tags[0] and '<image you want to rename>' in image.tags[0]: 
            version = image.tags[0].split("/")[-1]
            type(version)
            print("version is {}".format(version))
            docker_api.tag(image.tags[0],"<new repository>/{}".format(version))
    except Exception as Ex:
        print(image) 

After Renaming the images you can push these images in new repo:

docker images | grep <new repository> | awk '{print $1":"$2}' | xargs -L1 docker push
