🐳 dockermove

A simple modular automation tool to install and move Docker's data root directory to your $HOME or any custom location.

---

💡 Why It's Useful

By default, Docker stores all images, containers, and layers in /var/lib/docker.
On systems with limited root (/) partition space — such as minimal Linux installs, VMs, or laptops with small SSDs — this can quickly fill up your root drive and cause system instability.

dockermove solves this by:

• Relocating Docker's data to your home directory (or any other path, like /mnt/storage/docker).
• Automating the entire setup process: install, stop, clean, configure, and restart Docker.
• Making it modular, so each step can be customized or reused in other automation projects.

This tool is ideal for developers or power users running Docker on lightweight systems, dual-boot setups, or cloud VMs with small root partitions but large home volumes.

✨ Features

• Detects package manager automatically (apt, pacman, dnf, yay, paru)
• Installs or updates Docker if already installed
• Relocates all Docker data from /var/lib/docker to $HOME/.docker-root
• Cleans up existing Docker cache safely
• Sets up permissions and Docker group for user access
• Verifies that Docker is running with the new data root directory

---

🚀 Usage

git clone https://github.com/Hasib-4174/dockermove.git
cd dockermove
chmod +x dockermove.sh scripts/*.sh
./dockermove.sh

---

⚙️ Requirements

• Linux system with sudo privileges
• Active internet connection (for installing or updating Docker)
• Enough storage space in $HOME or the target directory

---

🧭 Example Output

🚀 Docker Relocation Automation Started

🔹 Detecting Package Manager
✅ Detected package manager: apt

🔹 Installing or Updating Docker
Docker not found, installing...

🔹 Setting Up New Docker Root
📁 Created ~/.docker-root

🔹 Restarting and Verifying
Docker Root Dir: /home/username/.docker-root
✅ Docker has been successfully relocated!

---

🛠️ Future Improvements

• Add Python-based version with config file (JSON/YAML)
• Add CLI flags (e.g., --path, --dry-run)
• Add rollback feature to revert to default /var/lib/docker
