Root Cause

Docker has consumed all available disk space with images, containers, volumes, and build cache.

generic

Workarounds

  1. 96% success Run docker system prune -a --volumes to reclaim space 
    Removes all stopped containers, unused images, networks, and volumes

    Sources: https://docs.docker.com/config/pruning/

  2. 88% success Set up regular cleanup with docker system prune in cron 
    Add 0 2 * * * docker system prune -af to crontab for nightly cleanup

Dead Ends

Common approaches that don't work:

  1. Deleting /var/lib/docker manually 90% fail

    Corrupts Docker's internal database; may brick the daemon

  2. Increasing disk size without pruning 55% fail

    Docker will fill the new space too if images are not cleaned up
