Reset_Docker/README.md

Docker Factory Reset Script for Ubuntu

A comprehensive Python script that completely resets Docker to a fresh installation state on Ubuntu systems. This script removes all containers, images, volumes, networks, build cache, and even wipes the Docker data directories to give you a clean slate.

🚨 Warning

This script is EXTREMELY DESTRUCTIVE!

It will permanently delete:

• ✗ All Docker containers (running and stopped)
• ✗ All Docker images
• ✗ All Docker volumes (including all data stored in them)
• ✗ All custom Docker networks
• ✗ All build cache
• ✗ All Docker system data (/var/lib/docker and /var/lib/containerd)

There is NO undo. All data will be permanently lost.

Only use this script if you:

• Want to completely reset Docker to a fresh state
• Are experiencing issues that require a clean Docker installation
• Are decommissioning a system and want to clean up Docker
• Understand that ALL Docker data will be lost

📋 Features

• ✅ Real-time output: See exactly what's happening as commands execute
• ✅ Progress indicators: Visual progress bars for batch operations
• ✅ Step-by-step execution: Clear indication of each phase
• ✅ Safety confirmation: Requires explicit confirmation before proceeding

4. Volumes: Removes all volumes
5. Prune: Clears build cache and system artifacts
6. Stop services: Stops docker and containerd
7. Delete directories: Removes /var/lib/docker and /var/lib/containerd
8. Start services: Restarts Docker and verifies with docker info
