Node Ports

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:

MQTT broker service (mqtt-svc): 30000
Frontend (frontend-svc): 30001
SocketIO: (socketio-svc): 30002
Controller (controller-svc): 30003
WebSocket (ws-svc): 30005

Before deploying the files, edit the frontend.yaml file to set the correct enviroment variables:

env:
    - name: NEXT_PUBLIC_REST_ENDPOINT
        value: "<FRONTEND_IP>:30003"
    - name: NEXT_PUBLIC_WS_ENDPOINT
        value: "<FRONTEND_IP>:30005"

kubectl apply -f $DEPLOYMENT_PATH/mqtt.yaml
kubectl apply -f $DEPLOYMENT_PATH/mqtt-adapter.yaml
kubectl apply -f $DEPLOYMENT_PATH/adapter.yaml
kubectl apply -f $DEPLOYMENT_PATH/controller.yaml
kubectl apply -f $DEPLOYMENT_PATH/socketio.yaml
kubectl apply -f $DEPLOYMENT_PATH/frontend.yaml
kubectl apply -f $DEPLOYMENT_PATH/ws.yaml
kubectl apply -f $DEPLOYMENT_PATH/ws-adapter.yaml

Checking cluster status:


kubectl get pods
kubectl get svc
