Optimize Docker Image Disk Usage with Docuum

Github repositories

• stepchowfun/docuum

  Docuum is a tool designed for Docker image management, specifically for performing least recently used (LRU) eviction to keep disk usage below a specified threshold. It addresses limitations in Docker's built-in eviction command, which uses image creation time rather than last usage time. Docuum listens for Docker events to track image usage and performs LRU eviction to optimize disk space. It is useful for scenarios like continuous integration (CI) workers and developer workstations, and it works well with tools like Toast and Docker Compose. Docuum respects parent-child relationships between images and provides various command-line options for customization.
