As someone testing out new Docker containers on the daily, both out of my interest in checking out new self-hosted services, as well as for surfacing cool new utilities here at XDA, I can have dozens of containers running simultaneously. And for the longest time, I didn’t notice just how much space Docker was eating up on my SSD. Until one day, I got a low storage warning on my NAS. That didn’t seem right, except it was. Docker was h***ding way more space than it really should be.
