Created June 18, 2024 05:25
Bash script to remove Docker Images using a whitelist and keeping a specified number of copies ... beyond what "docker system prune" does
#!/bin/bash

# Usage
# ~~~~~
# docker_image_purge list
# docker_image_purge [ remove ]
#
# By default, this command only shows what Docker images it'll remove.
# Use the optional "remove" command line parameter to actually remove them !
