Docker Cleanup Pro ⭐

Smart Docker cleanup that saves disk space without breaking things

Why Docker Cleanup Pro?

If you're a Docker user, you know the pain:

• Docker fills up disk space fast
• docker system prune is scary (it removes too much!)
• Developers waste hours managing Docker storage

Docker Cleanup Pro solves this with safe, smart cleanup that:

• ✅ Removes unused images while keeping recent versions
• ✅ Cleans dangling volumes safely
• ✅ Removes old containers intelligently
• ✅ Shows exactly what was cleaned and how much space was saved
• ✅ Includes dry-run mode to preview changes
• ✅ Saves rollback state for safety

Quick Start

Installation

# Install via pip
pip install docker-cleanup-pro

# Or install from source
git clone https://github.com/ahmad0303/docker-cleanup-pro.git
cd docker-cleanup-pro
pip install -e .

Basic Usage

# Safe cleanup (recommended for first-time users)
docker-cleanup --safe

# Dry run to see what would be removed
docker-cleanup --dry-run

# Aggressive cleanup (removes more)
docker-cleanup --aggressive

Features

Safe Mode (Recommended)

Removes unused Docker resources while keeping your system stable:

docker-cleanup --safe

What it does:

• Keeps last 3 versions of each image
• Removes containers stopped 7+ days ago
• Cleans dangling volumes only
• Removes build cache
• Shows space saved with detailed summary

Aggressive Mode

For maximum cleanup when you need disk space NOW:

docker-cleanup --aggressive

What it does:

• Keeps only 1 version of each image
• Removes containers stopped 1+ day ago
• More aggressive cleanup overall

Dry Run Mode

Preview what would be removed without making changes:

docker-cleanup --dry-run

Perfect for understanding the impact before running cleanup!

Selective Cleanup

Clean only specific resources:

# Only clean images
docker-cleanup --images

# Only clean containers
docker-cleanup --containers

# Only clean volumes
docker-cleanup --volumes

# Only clean build cache
docker-cleanup --build-cache

# Combine multiple options
docker-cleanup --images --build-cache

Custom Configuration

Fine-tune cleanup behavior:

# Keep 5 versions of each image
docker-cleanup --safe --keep-versions 5

# Keep containers from last 14 days
docker-cleanup --safe --keep-recent-days 14

# Combine custom settings
docker-cleanup --keep-versions 2 --keep-recent-days 3

Safety Features

Rollback Support

Every cleanup operation saves rollback information:

# Rollback state saved automatically
~/.docker-cleanup-rollback.json

Confirmation Prompts

Non-dry-run operations require confirmation:

⚠️  This will remove Docker resources. Continue? [y/N]:

Smart Version Keeping

Automatically keeps the most recent versions of images by creation date.

Protected Resources

• Running containers are never removed
• Recently stopped containers are kept (configurable)
• In-use images are automatically skipped
• Named volumes require explicit dangling status

Advanced Usage

CI/CD Integration

Use in automated pipelines:

# GitHub Actions example
- name: Cleanup Docker
  run: |
    docker-cleanup --safe --keep-versions 2

Cron Jobs

Schedule regular cleanup:

# Add to crontab (weekly cleanup)
0 2 * * 0 /usr/local/bin/docker-cleanup --safe

Docker-in-Docker

Works in Docker-in-Docker (DinD) environments:

FROM docker:dind
RUN apk add --no-cache python3 py3-pip
RUN pip3 install docker-cleanup-pro

Requirements

• Python: 3.8 or higher
• Docker: Any recent version
• Permissions: Access to Docker daemon (usually requires sudo/root or docker group membership)
