# LXC Container Deployment Guide

## Overview
Run **Gitea Mirror** in an isolated LXC container, either:

1. **Online, on a Proxmox VE host** – script pulls everything from GitHub
2. **Offline / LAN-only, on a developer laptop** – script pushes your local checkout + Bun ZIP

---

## 1. Proxmox VE (online, recommended for prod)

### Prerequisites
* Proxmox VE node with the default `vmbr0` bridge
* Root shell on the node
* Ubuntu 22.04 LXC template present (`pveam update && pveam download ...`)

### One-command install

```bash
# Community-maintained script for Proxmox VE by Tobias ([CrazyWolf13](https://github.com/CrazyWolf13))
# at [community-scripts/ProxmoxVED](https://github.com/community-scripts/ProxmoxVED)
sudo bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVED/main/install/gitea-mirror-install.sh)"
```

What it does:

* Uses the community-maintained script from ProxmoxVED
* Installs dependencies and Bun runtime
* Clones & builds `arunavo4/gitea-mirror`
* Creates a systemd service and starts it
* Sets up a random `JWT_SECRET` for security

Browse to:

```
http://<container-ip>:4321
```

---

## 2. Local testing (LXD on a workstation, works offline)

### Prerequisites

* `lxd` installed (`sudo apt install lxd`; `lxd init --auto`)
* Your repo cloned locally – e.g. `~/Development/gitea-mirror`
* Bun ZIP downloaded once:
  `https://github.com/oven-sh/bun/releases/latest/download/bun-linux-x64.zip`

### Offline installer script

```bash
git clone https://github.com/arunavo4/gitea-mirror.git   # if not already
curl -fsSL https://raw.githubusercontent.com/arunavo4/gitea-mirror/main/scripts/gitea-mirror-lxc-local.sh -o gitea-mirror-lxc-local.sh
chmod +x gitea-mirror-lxc-local.sh

sudo LOCAL_REPO_DIR=~/Development/gitea-mirror \
     ./gitea-mirror-lxc-local.sh
```

What it does:

* Launches privileged LXC `gitea-test` (`lxc launch ubuntu:22.04 ...`)
* Pushes **Bun ZIP** + tarred **local repo** into `/opt`
* Unpacks, builds, initializes DB
* Symlinks both `bun` and `bunx` → `/usr/local/bin`
* Creates a root systemd unit and starts it

Access from host:

```
http://$(lxc exec gitea-test -- hostname -I | awk '{print $1}'):4321
```

(Optional) forward to host localhost:

```bash
sudo lxc config device add gitea-test mirror proxy \
  listen=tcp:0.0.0.0:4321 connect=tcp:127.0.0.1:4321
```

## Health-check endpoint

Gitea Mirror includes a built-in health check endpoint at `/api/health` that provides:

- System status and uptime
- Database connectivity check
- Memory usage statistics
- Environment information

You can use this endpoint for monitoring your deployment:

```bash
# Basic check (returns 200 OK if healthy)
curl -I http://<container-ip>:4321/api/health

# Detailed health information (JSON)
curl http://<container-ip>:4321/api/health
```

## Troubleshooting

| Check          | Command                                               |
| -------------- | ----------------------------------------------------- |
| Service status | `systemctl status gitea-mirror`                       |
| Live logs      | `journalctl -u gitea-mirror -f`                       |
| Verify Bun     | `bun --version && bunx --version`                     |
| DB perms       | `chown -R root:root /opt/gitea-mirror/data` (Proxmox) |

## Connecting LXC and Docker Containers

If you need your LXC container to communicate with Docker containers:

1. On your host machine, create a bridge network:
   ```bash
   docker network create gitea-network
   ```

2. Find the bridge interface created by Docker:
   ```bash
   ip a | grep docker
   # Look for something like docker0 or br-xxxxxxxx
   ```

3. In Proxmox, edit the LXC container's network configuration to use this bridge.
