# 🛠️ 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:

```bash
# cd into the docker folder
wget -qO update-docker.sh https://gitea.featherer.xyz/nono/update-docker/raw/branch/main/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/update-docker/raw/branch/main/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.
