## 🧩 Global Installation (via `/etc/profile.d`)

```bash
sudo curl -fsSL https://gitea.wssk.ru/sk/docker-rootless-install/raw/branch/master/scripts/docker-installer-init.sh \
  -o /etc/profile.d/docker-installer-init.sh

```

After that, every user upon terminal login will:

- Get a copy of the installer script in `~/scripts/docker-install.sh`

## 🔄 Auto-update

The script checks the remote `version` file and updates itself automatically if a newer version is available.

## 🧨 Uninstallation

The menu includes an option **"Remove Docker and ALL data"**, which deletes:

- Containers  
- Images  
- Volumes  
- Rootless Docker configs  
- Docker and Compose binaries  

⚠️ Use with caution!
