Docker preserve images policy Can I configure Docker in a such way that it will store only certain amount of tags for the given image e.g. docker images

REPOSITORY                     TAG                                      IMAGE ID            CREATED             SIZE

and I want to store locally only N most recent images. Can I configure some kind of policy or is there any common script that runs rotation with cron or something like that? Other best practices/suggestions are welcome.
I do not believe that there is a way to set this as a global policy.  However, there is a simple command you can run that will "prune" or remove your unused images.

You will want to use docker image prune --filter [options] to achieve this.  Check out the official documentation for information on how to best filter.  As a best practice you should be tagging your images which will make managing of them easier using tools like this.
