docker-cleanup-script-safe-mode

A safety-first Bash wrapper around docker system df and docker system prune that defaults to SAFE_MODE=true and asks for confirmation before removal.

Key features

• Shows current Docker disk usage first
• Defaults to non-destructive safe mode
• Interactive confirmation before prune when safe mode is off

Project structure

• docker_cleanup.sh — Main cleanup script

Requirements

• Bash
• Docker CLI and daemon access

Setup

git clone https://github.com/biprajit007/docker-cleanup-script-safe-mode.git
cd docker-cleanup-script-safe-mode
chmod +x docker_cleanup.sh

Usage

Inspect only

./docker_cleanup.sh

Allow pruning

SAFE_MODE=false ./docker_cleanup.sh

Safety notes

• SAFE_MODE is intentionally true by default.
• docker system prune -a --volumes can delete stopped containers, unused images, networks, and volumes. Review the prompt carefully.

Limitations / next improvements

• No per-resource filtering or dry-run diff beyond docker system df
• Interactive prompt makes unattended automation awkward
