Cleanup Docker Anonymous Volumes

Description

This Ansible role installs and executes dockreap, a tool designed to clean up unused anonymous Docker volumes (including symlinks and their targets) to maintain a tidy Docker environment.

Overview

The role installs dockreap using Python tooling and runs it with the --no-confirmation flag to ensure automatic, non-interactive cleanup.

Purpose

This role automates the removal of orphaned Docker volumes that consume unnecessary disk space. It is especially useful in backup, CI/CD, or maintenance routines.

Features

  • Automated Cleanup: Runs dockreap --no-confirmation to remove unused anonymous Docker volumes.

  • Python-based Install: Installs dockreap (isolated, system-friendly CLI install).

  • Idempotent Execution: Ensures the tool is installed and run only once per playbook run.

  • Symlink-Aware: Safely handles symlinked _data directories and their targets.
