For those interested, this is built into rkt with `rkt gc`, for an easy cron job experience. You can set a grace period for how old an image has to be to qualify.

Check it out at https://coreos.com/rkt/docs/latest/subcommands/gc.html

Would you recommend using rkt in production instead of Docker? My impression was that rkt is even more immature, but maybe that's entirely wrong.

I'm biased as I work at CoreOS but I'll add that it should be a drop-in replacement for Kubernetes.

`kubelet --container-runtime=rkt` and be on your way.
