+# 🚀 Proxmox Deployment Template (TurnKey Node.js)
+
+**Use this guide to deploy ANY Node.js application to a TurnKey Linux LXC Container.**
+
+---
+
+## 📋 Prerequisites
+
+1.  **Project**: A Node.js application (Express, Next.js, etc.) in a Git repository.
+2.  **Server**: A Proxmox TurnKey Node.js Container.
+3.  **Access**: Root SSH password for the container.
+4.  **Domain (Optional)**: If using Cloudflare Tunnel.
+
+---
+
+## 🛠️ Step 1: Prepare Your Project
+
+Ensure your project is ready for production:
+
+1.  **Port Configuration**: Ensure your app listens on a configurable port or a fixed internal port (e.g., `4001`).
+    ```javascript
+    // server.js
+    const PORT = process.env.PORT || 4001;
+    app.listen(PORT, ...);
+    ```
+
+2.  **Git Ignore**: Ensure `node_modules` and config files with secrets are ignored.
+    ```gitignore
+    node_modules/
+    .env
+    config.json
+    ```
+
+---
+
+## 🖥️ Step 2: One-Time Server Setup
+
+SSH into your new container:
+```bash
+ssh root@<YOUR_SERVER_IP>
+```
+
+Run these commands to prepare the environment:
+
+### 1. Install Essentials
+```bash
+apt-get update && apt-get install -y git
+```
+
+### 2. Prepare Directory
+```bash
+# Standard web directory
+mkdir -p /var/www/<APP_NAME>
+cd /var/www/<APP_NAME>
+
+# Clone your repo (Use Basic Auth with Token if private)
+# Format: https://<USER>:<TOKEN>@github.com/<ORG>/<REPO>.git
+git clone <YOUR_REPO_URL> .
+
+# Install dependencies
+npm install
+```
+
+### 3. Setup Permissions
+```bash
+# Give ownership to www-data (Nginx user)
+chown -R www-data:www-data /var/www/<APP_NAME>
+```
+
+---
+
+## ⚙️ Step 3: Application Configuration
+
+### 1. Systemd Service
+Create a service file to keep your app running.
+
+Create `/etc/systemd/system/<APP_NAME>.service`:
+```ini
+[Unit]
+Description=<APP_NAME> Service
+After=network.target
+
+[Service]
+Type=simple
+User=root
+# OR use 'www-data' if app doesn't need root ports
+# User=www-data
+WorkingDirectory=/var/www/<APP_NAME>
+ExecStart=/usr/local/bin/node server.js
+Restart=always
+Environment=NODE_ENV=production
+Environment=PORT=4001
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable and start:
+```bash
+systemctl daemon-reload
+systemctl enable <APP_NAME>
+systemctl start <APP_NAME>
+```
+
+### 2. Nginx Reverse Proxy
+Configure Nginx to forward port 80 to your app (Port 4001).
+
+Create `/etc/nginx/sites-available/<APP_NAME>`:
+```nginx
+server {
+    listen 80;
+    server_name _;
+
+    root /var/www/<APP_NAME>;
+    index index.html;
+
+    # Serve static files (Optional)
+    location / {
+        try_files $uri $uri/ =404;
+    }
+
+    # Proxy API/Dynamic requests
+    location /api {
+        proxy_pass http://localhost:4001;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+```
+
+Enable site:
+```bash
+# Remove defaults
+rm -f /etc/nginx/sites-enabled/default
+rm -f /etc/nginx/sites-enabled/nodejs
+
+# Link new site
+ln -s /etc/nginx/sites-available/<APP_NAME> /etc/nginx/sites-enabled/
+
+# Reload
+nginx -t && systemctl reload nginx
+```
+
+---
+
+## ☁️ Step 4: Cloudflare Tunnel (Secure Access)
+
+Expose your app securely without opening router ports.
+
+### 1. Install Cloudflared
+```bash
+# Add Key
+mkdir -p --mode=0755 /usr/share/keyrings
+curl -fsSL https://pkg.cloudflare.com/cloudflare-public-v2.gpg | tee /usr/share/keyrings/cloudflare-public-v2.gpg >/dev/null
+
+# Add Repo
+echo 'deb [signed-by=/usr/share/keyrings/cloudflare-public-v2.gpg] https://pkg.cloudflare.com/cloudflared any main' | tee /etc/apt/sources.list.d/cloudflared.list
+
+# Install
+apt-get update && apt-get install -y cloudflared
+```
+
+### 2. Create Tunnel
+```bash
+cloudflared tunnel login
+cloudflared tunnel create <TUNNEL_NAME>
+# Follow on-screen instructions to map domain -> http://localhost:4001
+```
+
+---
+
+## 🔄 Step 5: Automated Updates (PowerShell)
+
+Create a script `deploy-remote.ps1` in your project root to automate updates.
+
+**Pre-requisite**: Create `deploy-config.json` (Add to .gitignore!):
+```json
+{
+  "host": "<SERVER_IP>",
+  "username": "root",
+  "password": "<SSH_PASSWORD>",
+  "remotePath": "/var/www/<APP_NAME>"
+}
+```
+
+**Script `deploy-remote.ps1`**:
+```powershell
+# Reads config and updates remote server
+$Config = Get-Content "deploy-config.json" | ConvertFrom-Json
+$User = $Config.username; $HostName = $Config.host; $Pass = $Config.password
+$RemotePath = $Config.remotePath
+
+# Commands to run remotely
+$Cmds = "
+    cd $RemotePath
+    echo '⬇️ Pulling code...'
+    git pull
+    echo '📦 Installing deps...'
+    npm install
+    echo '🚀 Restarting service...'
+    systemctl restart <APP_NAME>
+    systemctl status <APP_NAME> --no-pager
+"
+
+echo y | plink -ssh -t -pw $Pass "$User@$HostName" $Cmds
+```
+
+**Usage**: Just run `./deploy-remote.ps1` to deploy!
