# 🛠️ Maintenance Script for Docker Containers
Automates updating your Docker containers on Debian-based systems by pulling the latest images, restarting services, and cleaning up unused resources.
---
## 🚀 Installation, Setup & Running
Download the maintenance script to your Docker project directory:
# cd into the docker folder
```bash
# cd into the docker folder
wget -qO update-docker.sh https://gitea.featherer.xyz/nono/Scripts/raw/branch/main/update-docker/update-docker.sh
source update-docker.sh
```
Or, when run locally (replace the ip address to your own)
```bash
# cd into the docker folder
wget -qO update-docker.sh http://10.1.0.102:3000/nono/Scripts/raw/branch/main/update-docker/update-docker.sh
source update-docker.sh
```
---
## 🔄 What It Does
1. **Updates system packages**
Runs `apt update` and `apt upgrade -y` to ensure your host is up to date.
2. **Refreshes Docker services**
Executes `docker-compose pull`, `docker-compose down`, and `docker-compose up -d` to fetch new images and restart containers.
3. **Cleans up unused resources**
Calls `docker system prune -a -f` to remove dangling images, stopped containers, and unused networks.
4. **Verifies running containers**
Lists active containers with `docker ps` so you can confirm everything is up and running.
---
## 📝 Prerequisites
- **Debian-based OS** (e.g., Debian, Ubuntu)
- **Docker** & **Docker Compose** installed
- A user with **sudo** privileges or in the **docker** group
