# ☁️ Welcome to Numbus 🚀

Welcome to the **Numbus Server** project! This repository provides a complete selection of highly customizable NixOS configurations to deploy **home servers**, **backup servers**, **computers**, **TVs** in an automated manner. Deploy devices in hours instead of days !

## 🚀 Getting Started

The entire deployment process is automated around a bash script. It helps to dynamically adapt the configuration to your hardware, network environment, and secrets.

### Requirements :
#### For numbus-server :
-   A NixOS-based machine to deploy from
-   A NixOS-based live machine to deploy to
-   An email address with automated mail sending support
-   A valid, public domain name

#### For numbus-backup-server :
-   A NixOS-based machine to deploy from
-   A NixOS-based live machine to deploy to
-   An email address with automated mail sending support
-   A valid domain name

#### For numbus-computer :
-   A NixOS-based machine to deploy from
-   A NixOS-based live machine to deploy to

#### For numbus-tv :
-   A NixOS-based machine to deploy from
-   A NixOS-based live machine to deploy to

### On your Nix-based machine :

**1. Clone the Repository :**

```bash
git clone https://git.numbus.eu/raphael/numbus.git
cd numbus
```

**2. (Optional) Fill in the configuration file :**

This step is globally recommended as it reduces the risks of typos in the credentials. It also is better suited for repeated deployments to multiple machines.

```bash
nano $your_choosed_device.conf
```

Example: if you want to deploy a server

```bash
nano numbus-server.conf
```

**3. Run the Deployment Script :**

```bash
./deploy.sh
```

**4. Follow the script's Prompts :**

> If you followed **step 2**, then choose non-interactive mode.

> If you skipped **step 2**, then choose interactive mode.

The script will guide you through the setup process, including choosing a deployment mode and providing the necessary information. Once completed, the script will:

-   Adapt the configuration to your machine.
-   Generate SSH and `sops` keys.
-   Encrypt secrets for secure storage.
-   Generate configuration files for Podman services.
-   Deploy the NixOS configuration to the remote using `nixos-anywhere`.
-   Verify the deployment and guide you through the final setup of the web UIs.

## 🔧 Deployment Modes

The `deploy.sh` script offers three modes to suit your needs:

1.  **Interactive Mode:** The script will prompt you for all necessary configuration values, such as the target host's IP address, the disk to install on, domain names, and API tokens.
2.  **Non-interactive Automated Mode:** The script can read configuration values from a file, allowing for unattended deployments.
3.  **Update and Maintain Mode:** This mode allows you to update a remote system on which this NixOS configuration has already been deployed.
