GitOps repository for the transportation robot battery-simulation demo on OpenShift

Application components

• AMQ Broker Operator: Manages the AMQ broker StatefulSet
• AMQ Broker: Configured as a MQTT broker
• Battery simulator: Quarkus component that simulates the battery of a driving transportation robot in a plant (shop floor). The BMS of the device is sending telemetry data to the device local MQTT broker.
• InfluxDB: Local time series database, configured with auto setup.
• influx-exporter: Exports time series data every 10 minutes to a S3 bucket for AI model training. Has a REST API for manual export.
• data-ingester: Quarkus component that reads realtime data from MQTT and stores it InfluxDB.
• BMS Device Dashboard: Angular component that displays the realtime battery telemetry data and provides AI inference capabilities. Can also simulate battery temperature anomalies.
• mqtt2ws: Camel Quarkus component that reads realtime data from MQTT and exposes it as Websocket for the BMS Dashboard for visualization.

Demo Installation

The demo application requires an S3 compatible Object storage. We'll use MinIO for the demo.

1. Install MinIO Argo application

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

Install the MinIO argo application:

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

2. Install the transportation robot battery-simulation Argo application

Create a new Argo application that points to apps/battery-demo/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: apps/battery-demo/groups/dev
    repoURL: https://github.com/ortwinschneider/ai-edge-battery-sim-gitops
    targetRevision: HEAD
  sources: []
  project: default
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

Install the transportation robot battery-simulation Argo application:

oc apply -f battery-demo-app.yaml -n openshift-gitops

MinIO Login

You can log in to the MinIO Web UI with user minio and password minio123.

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")
