-<b>Node Ports</b>
-
-For this deployment, we are not using a load balancer and kubernetes is deployed on-premises so we are using Nodeports to insource the client traffic into cluster. below the ports set on deployment files:
-
-1. MQTT broker service (mqtt-svc): 30000
-2. Frontend (frontend-svc): 30001
-3. SocketIO: (socketio-svc): 30002
-4. Controller (controller-svc): 30003
-5. WebSocket (ws-svc): 30005
-
-Before deploying the files, edit the frontend.yaml file to set the correct enviroment variables:
-
-```yaml
-env:
-    - name: NEXT_PUBLIC_REST_ENDPOINT
-        value: "<FRONTEND_IP>:30003"
-    - name: NEXT_PUBLIC_WS_ENDPOINT
-        value: "<FRONTEND_IP>:30005"
