GitOps repo for battery-simulation demo

Components

• AMQ Broker Operator
• AMQ Broker: Used as MQTT broker
• Battery simulator: Quarkus component that simulates the battery of a driving Tesla S. The BMS is sending telemetry data to the MQTT broker.
• InfluxDB: Time series database, configured with auto setup
• data-ingester: Quarkus component that reads data from MQTT and stores it InfluxDB
• BMS Dashboard: Angular component that displays the battery telemetry data in realtime and serves as a frontend for a GenAI chatbot.
• mqtt2ws: Camel Quarkus component that reads data from MQTT and exposes it as Websocket for the BMS Dashboard

Installation

Create a new Argo application that points to groups/dev. It will install all the components in the battery-demo namespace

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: battery-demo
  namespace: openshift-gitops
spec:
  destination:
    name: ''
    namespace: ''
    server: https://kubernetes.default.svc
  source:
    path: groups/dev
    repoURL: https://github.com/ortwinschneider/battery-simulation-gitops
    targetRevision: HEAD
  sources: []
  project: default
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

Install the argo app:

oc apply -f argo-app.yaml -n openshift-gitops

Exploring the data in InfluxDB

Login to the InfluxDB Web UI with user admin and password password. Navigate to Explore and create a query with Script Editor. Use this query to find the data from the last hour:

from(bucket: "bms")
  |> range(start: -1h)
  |> filter(fn: (r) => r._measurement == "battery_data")

Troubleshooting

It might be necessary to restart the battery-simulation pod when the AMQ broker is ready. Check the logs to see if the component is sending the data.
