🛠️ 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
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)

# 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.
