This tool is projected to be used as a "Sunday" cronjob for registries, gitlab runners and so on.
Setup dockermor_images.pl as one cron job.
dockermor.pl:
--all -- operate on all found resources. If this is
specified alongside individual resources, this
option takes precedence
--resource-type=image -- required
--older-than-days=<DAYS> -- time in days that the resource needs to be older than
--dry-run -- perform dry run
--dry-run-prefix=<STRING> -- prefix of dry run output
[resource1 resource2 ...] -- names of the resources to operate on
