MicroNAS

Lightweight web GUI to manage SMB shares, NFS exports, and users 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:

modprobe nfsd
echo nfsd >> /etc/modules

Install

Run everything below inside the LXC container as root.

1. System dependencies

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

2. Clone the repo

git clone https://gitea.honeyy.duckdns.org/Honey/MicroNAS.git /opt/micronas

3. Python environment

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

4. Credentials

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

5. systemd service

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

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

---

Updates

cd /opt/micronas
git pull
systemctl restart micronas

Network

The service binds to 0.0.0.0:5000 — accessible from any LAN device at http://<lxc-ip>:5000.

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

LAN or Tailscale only — never expose to the internet.

Dev / test

# Quick local run (no gunicorn needed, must have flask installed):
MICRONAS_USER=admin MICRONAS_PASS=secret flask --app app.py run --debug --host=0.0.0.0

Note: SMB/NFS/user management calls require root and the relevant daemons — run on the actual LXC for full testing.

Auth

All routes require a login session. Go to http://<lxc-ip>:5000 — you will be redirected to the login page automatically. Credentials come from MICRONAS_USER / MICRONAS_PASS in /etc/micronas.env. If MICRONAS_PASS is not set the app starts unprotected and logs a warning — do not do this in production.

Mounting shares on a Linux client

Replace <nas-ip> with your LXC's IP address throughout.

SMB (Samba)

# Install client tools
apt install cifs-utils

# One-time mount
mount -t cifs //<nas-ip>/sharename /mnt/nas -o username=youruser,password=yourpass

# Permanent — add to /etc/fstab:
//<nas-ip>/sharename  /mnt/nas  cifs  username=youruser,password=yourpass,_netdev  0  0

For better security, store credentials in a file instead of putting them in fstab:

# Create /etc/nas-credentials (root-only):
cat > /etc/nas-credentials <<EOF
username=youruser
password=yourpass
EOF
chmod 600 /etc/nas-credentials

# Then in /etc/fstab:
//<nas-ip>/sharename  /mnt/nas  cifs  credentials=/etc/nas-credentials,_netdev  0  0

NFS

# Install client tools
apt install nfs-common

# One-time mount
mount -t nfs <nas-ip>:/srv/data /mnt/nas

# Permanent — add to /etc/fstab:
<nas-ip>:/srv/data  /mnt/nas  nfs  defaults,_netdev  0  0

_netdev tells the system to wait for the network before mounting — important for both SMB and NFS so the mount doesn't fail on boot.

Multiple networks (e.g. LAN + Tailscale): enter both subnets space-separated in the Clients field when creating the export, e.g. 192.168.1.0/24 100.64.0.0/10. Both get the same ro/rw setting.

Useful commands

# List available NFS exports from the server
showmount -e <nas-ip>

# Unmount
umount /mnt/nas

# Mount all fstab entries (after editing fstab)
mount -a
