# MicroNAS

Lightweight web GUI to manage SMB shares, NFS exports, and quotas on a single home server (Proxmox LXC/VM). Runs directly on the host as a systemd service.

## Proxmox LXC setup

Use a **privileged** Debian/Ubuntu container — required for the NFS server kernel module and quotas.

On the **Proxmox host**, load the NFS kernel module before starting the container:

```bash
modprobe nfsd
echo nfsd >> /etc/modules
```

## Install

Run everything below **inside the LXC container** as root.

### 1. System dependencies

```bash
apt update
apt install -y git samba nfs-kernel-server quota python3 python3-venv
```

### 2. Clone the repo

```bash
git clone https://github.com/yourusername/micronas.git /opt/micronas
# or if you're self-hosting:
# git clone git@yourserver:micronas.git /opt/micronas
```

### 3. Python environment

```bash
python3 -m venv /opt/micronas/venv
/opt/micronas/venv/bin/pip install flask gunicorn
```

### 4. Credentials

```bash
cat > /etc/micronas.env <<EOF
MICRONAS_USER=admin
MICRONAS_PASS=changeme
EOF
chmod 600 /etc/micronas.env
```

### 5. systemd service

```bash
cp /opt/micronas/micronas.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable --now micronas
```

Open `http://<lxc-ip>:5000` in your browser.

## Updates

```bash
cd /opt/micronas
git pull
systemctl restart micronas
```

## Network

The service binds to `127.0.0.1:5000` by default. To reach it directly from the LAN, change `-b 127.0.0.1:5000` to `-b 0.0.0.0:5000` in `micronas.service`, then run `systemctl daemon-reload && systemctl restart micronas`.

For HTTPS, put nginx in front as a reverse proxy.

LAN or Tailscale only — never expose to the internet.

## Dev / test

```bash
# Quick local run (no gunicorn needed):
MICRONAS_USER=admin MICRONAS_PASS=secret flask --app app.py run --debug --host=0.0.0.0

# Or with docker-compose (UI only — systemctl/samba calls won't work):
docker compose up
```

## Auth

All routes require HTTP Basic Auth. Credentials come from `MICRONAS_USER` / `MICRONAS_PASS` environment variables (set via `/etc/micronas.env` in production). If `MICRONAS_PASS` is not set the app starts unprotected and logs a warning — don't do this in production.
