# 🐳 Docker Setup Script for Debian
|
||||
|
||||
This script automates the installation of Docker and optionally helps you set up a working directory and a `compose.yaml` as well as a `.env` file.
|
||||
|
||||
---
|
||||
|
||||
## 🚀 How to Use
|
||||
|
||||
run the following script
|
||||
|
||||
```bash
|
||||
wget -qO docker-debian.sh https://gitea.featherer.xyz/nono/docker-debian/raw/branch/main/docker-debian.sh
|
||||
source docker-debian.sh
|
||||
```
|
||||
|
||||
Or when run locally (using your own ip address)
|
||||
|
||||
```bash
|
||||
wget -qO docker-debian.sh http://10.1.0.102:3000/nono/docker-debian/raw/branch/main/docker-debian.sh
|
||||
source docker-debian.sh
|
||||
```
