# Deployment Guide for LXC Container

This guide explains how to deploy this Hugo website to an LXC container running Ubuntu (or similar). The site runs as a live Hugo server with a reverse proxy forwarding requests.

## Prerequisites

- LXC container with Arch Linux (or adjust package manager commands for your distribution)
- SSH access to the container
- Git installed on container
- Domain name `dustin.coffee` pointing to container's IP address (or adjust baseURL in `hugo.toml`)

## Step 1: Install Hugo Extended on LXC

**Important**: This theme requires Hugo **extended** version ≥ 0.123.0. Ubuntu's default apt repository provides an outdated version (v0.123.7). You must install a newer extended version.

### Option A: Using installation script (Recommended)

Copy the `install-hugo.sh` script to your container and run it:

```bash
# On your container, as root or with sudo:
chmod +x install-hugo.sh
./install-hugo.sh
```

### Option B: Manual installation for Ubuntu/Debian

```bash
# Remove old Hugo if installed
sudo apt remove -y hugo

# Add Hugo APT repository
ARCH=$(dpkg --print-architecture)
echo "deb [arch=${ARCH} signed-by=/etc/apt/keyrings/hugo.gpg] https://hugo-apt.8hob.io latest main" | sudo tee /etc/apt/sources.list.d/hugo.list
sudo chmod 644 /etc/apt/sources.list.d/hugo.list

# Add signing key
sudo mkdir -p /etc/apt/keyrings
sudo wget -O /etc/apt/keyrings/hugo.gpg https://hugo-apt.8hob.io/signing-key
sudo chmod 644 /etc/apt/keyrings/hugo.gpg

# Pin repository priority
echo 'Package: hugo
Pin: origin "hugo-apt.8hob.io"
Pin-Priority: 520' | sudo tee /etc/apt/preferences.d/hugo
sudo chmod 644 /etc/apt/preferences.d/hugo

# Install Hugo Extended
sudo apt update
sudo apt install -y hugo

# Install git (required for Hugo modules)
sudo apt install -y git
```

### Verify installation

Check that you have the extended version:

```bash
hugo version
hugo env | grep HUGO_EXTENDED
# Should show: HUGO_EXTENDED=true
```

If `hugo version` shows v0.123.7 or earlier, the installation failed. Try Option B or install the binary manually from [Hugo releases](https://github.com/gohugoio/hugo/releases).

## Step 2: Clone Repository

Clone your git repository to a directory, e.g., `/srv/www/dustin.coffee`:

```bash
sudo mkdir -p /srv/www
sudo chown $USER:$USER /srv/www
cd /srv/www
git clone <your-git-repo-url> dustin.coffee
cd dustin.coffee

# Initialize theme submodule (required for hello-friend-ng theme)
git submodule update --init --recursive
```

## Step 3: Run Hugo Server (Reverse Proxy Setup)

Since you're using a reverse proxy pointing to the LXC container, run Hugo as a live server:

```bash
cd /srv/www/dustin.coffee
hugo server --bind 0.0.0.0 --port 1313 --baseURL=https://dustin.coffee --appendPort=false --disableLiveReload
```

**Important flags:**
- `--bind 0.0.0.0` – Listen on all network interfaces
- `--port 1313` – Port for the reverse proxy to forward to (adjust if different)
- `--baseURL=https://dustin.coffee` – Your public domain (must match reverse proxy)
- `--appendPort=false` – Don't include port 1313 in generated URLs (critical for correct links)
- `--disableLiveReload` – Disable live reload in production

### Systemd Service (Recommended for production)

Create `/etc/systemd/system/hugo-dustin.service`:

```ini
[Unit]
Description=Hugo Server for dustin.coffee
After=network.target

[Service]
Type=simple
User=www-data
Group=www-data
WorkingDirectory=/srv/www/dustin.coffee
ExecStart=/usr/bin/hugo server --bind 0.0.0.0 --port 1313 --baseURL=https://dustin.coffee --appendPort=false --disableLiveReload
Restart=on-failure

[Install]
WantedBy=multi-user.target
```

**Adjust paths:**
- Replace `/usr/bin/hugo` with `hugo` if installed via apt repository
- Set `User`/`Group` to your LXC user if not www-data
- Update `WorkingDirectory` to your site path

Enable and start the service:

```bash
sudo systemctl daemon-reload
sudo systemctl enable hugo-dustin
sudo systemctl start hugo-dustin
```

Check status: `sudo systemctl status hugo-dustin`

## Step 4: Reverse Proxy Configuration

SSL/TLS encryption should be configured at your reverse proxy level (not Hugo). 

Hugo itself runs on HTTP (port 1313). Your reverse proxy should:
- Terminate SSL at the proxy (HTTPS on port 443)
- Forward HTTP requests to Hugo on port 1313
- Set appropriate `X-Forwarded-*` headers if needed

**If using Caddy, Traefik, or another reverse proxy:** Consult your proxy's documentation for SSL configuration. Most modern proxies automatically handle SSL with Let's Encrypt.

**Important:** Ensure your reverse proxy forwards requests to `http://<lxc-internal-ip>:1313` (or `localhost:1313` if proxy runs on same container). The domain `dustin.coffee` must resolve to your reverse proxy's public IP.

## Step 5: Automation Script

Create a deployment script `deploy.sh` in the repository root:

```bash
#!/bin/bash
# deploy.sh - update site and restart Hugo server

set -e

cd /srv/www/dustin.coffee

echo "Pulling latest changes from git..."
git pull

echo "Updating theme submodule..."
git submodule update --init --recursive

echo "Restarting Hugo server..."
sudo systemctl restart hugo-dustin

echo "Deployment completed at $(date)"
```

Make it executable:

```bash
chmod +x deploy.sh
```

Now after SSH-ing into the container, you can run `./deploy.sh` to update the site.

## Notes

- Update the `baseURL` in `hugo.toml` if your domain changes.
- The site uses the `hello-friend-ng` theme as a git submodule.
- Blog posts are stored in `content/posts/` as markdown files.
- To add new blog posts, create markdown files in `content/posts/` on your development machine, push to git, then run the deploy script on the container.

## Troubleshooting

- If Hugo server fails to start, check logs: `sudo journalctl -u hugo-dustin -f`
- If Hugo fails to build, check Hugo version matches the one used in development.
- If blog post URLs are incorrect, verify `permalinks` configuration in `hugo.toml`.
- If reverse proxy shows 404, ensure Hugo server is running on port 1313 and reverse proxy forwards to correct port.

## Updating

To update the site after making changes on your development machine:

1. Push changes to your git server
2. SSH into LXC container
3. Navigate to site directory: `cd /srv/www/dustin.coffee`
4. Run `./deploy.sh`
