+# Docker Swarm Deployment Guide (IPvlan)
+
+This guide describes how to deploy **NetAlertX** in a **Docker Swarm** environment using an `ipvlan` network. This enables the container to receive a LAN IP address directly, which is ideal for network monitoring.
+
+---
+
+## ⚙️ Step 1: Create an IPvlan Config-Only Network on All Nodes
+
+> Run this command on **each node** in the Swarm.
+
+```bash
+docker network create -d ipvlan \
+  --subnet=192.168.1.0/24 \              # 🔧 Replace with your LAN subnet
+  --gateway=192.168.1.1 \                # 🔧 Replace with your LAN gateway
+  -o ipvlan_mode=l2 \
+  -o parent=eno1 \                       # 🔧 Replace with your network interface (e.g., eth0, eno1)
+  --config-only \
+  ipvlan-swarm-config
+```
+
+---
+
+## 🖥️ Step 2: Create the Swarm-Scoped IPvlan Network (One-Time Setup)
+
+> Run this on **one Swarm manager node only**.
+
+```bash
+docker network create -d ipvlan \
+  --scope swarm \
+  --config-from ipvlan-swarm-config \
+  swarm-ipvlan
+```
+
+---
+
+## 🧾 Step 3: Deploy NetAlertX with Docker Compose
+
+Use the following Compose snippet to deploy NetAlertX with a **static LAN IP** assigned via the `swarm-ipvlan` network.
+
+```yaml
+services:
+  netalertx:
+    image: ghcr.io/jokob-sk/netalertx:latest
+    ports:
+      - 20211:20211
+    volumes:
+      - /mnt/YOUR_SERVER/netalertx/config:/app/config:rw
+      - /mnt/YOUR_SERVER/netalertx/db:/netalertx/app/db:rw
+      - /mnt/YOUR_SERVER/netalertx/logs:/netalertx/app/log:rw
+    environment:
+      - TZ=Europe/London
+      - PORT=20211
+    networks:
+      swarm-ipvlan:
+        ipv4_address: 192.168.1.240     # ⚠️ Choose a free IP from your LAN
+    deploy:
+      mode: replicated
+      replicas: 1
+      restart_policy:
+        condition: on-failure
+      placement:
+        constraints:
+          - node.role == manager        # 🔄 Or use: node.labels.netalertx == true
+
+networks:
+  swarm-ipvlan:
+    external: true
+```
+
+---
+
+## ✅ Notes
+
+* The `ipvlan` setup allows **NetAlertX** to have a direct IP on your LAN.
+* Replace `eno1` with your interface, IP addresses, and volume paths to match your environment.
+* Make sure the assigned IP (`192.168.1.240` above) is not in use or managed by DHCP.
+* You may also use a node label constraint instead of `node.role == manager` for more control.
