+
+This is a helpful way to keep your containers from running out of space. Create a auto-prune cron job and put it in `etc/cron.daily`.
+
+```bash
+nano /etc/cron.daily/docker-prune
+```
+
+```bash
+#!/bin/bash
+
+UUID=00000000-0000-0000-0000-0000000000
+
+curl -m 5 --retry 5 https://healthchecks.io/ping/${UUID}/start &>/dev/null
+docker system prune --volumes -af
+curl -m 5 --retry 5 https://healthchecks.io/ping/${UUID} &>/dev/null
+```
+
+This also includes a ping out to [healthcheck.io](https://healthchecks.io), which is a really handy thing to track your cron jobs. You can also self host the service.
