Docuum
Docuum performs least recently used (LRU) eviction of Docker images to keep disk usage below a configurable threshold.
What is Docuum?
Docuum is a tool that automatically removes Docker images based on least recently used (LRU) eviction to manage disk space. It addresses limitations in Docker's built-in pruning by using actual image usage time rather than creation time, preventing the deletion of frequently used images that are costly to rebuild or pull.
Developers and system administrators working in environments where Docker images accumulate over time, such as continuous integration (CI) workers, developer workstations, and production Kubernetes nodes.
Developers choose Docuum over Docker's built-in pruning because it evicts images based on actual usage tracked via Docker events, ensuring frequently used images are preserved. It also operates efficiently by using no CPU resources when there is no Docker activity and evicts images immediately when disk usage exceeds a configurable threshold.
