• Helm repo name: united-manufacturing-hub
• URL: https://repo.umh.app

Then click Add.

1. Open the Workloads tab.
2. From the Deployment section, delete the following deployments:
   • united-manufacturing-hub-barcodereader
   • united-manufacturing-hub-factoryinsight-deployment
   • united-manufacturing-hub-kafkatopostgresql
   • united-manufacturing-hub-mqttkafkabridge
   • united-manufacturing-hub-iotsensorsmqtt
   • united-manufacturing-hub-opcuasimulator-deployment
3. From the StatefulSet section, delete the following statefulsets:
   • united-manufacturing-hub-mqttbridge
   • united-manufacturing-hub-hivemqce

Now everything is ready to upgrade the Helm chart.

       name: HighIntegrity
       send_direction: to_remote
       topic: ^ia\.(([^r.](\d|-|\w)*)|(r[b-z](\d|-|\w)*)|(ra[^w]))\.(\d|-|\w|_)+\.(\d|-|\w|_)+\.((addMaintenanceActivity)|(addOrder)|(addParentToChild)|(addProduct)|(addShift)|(count)|(deleteShiftByAssetIdAndBeginTimestamp)|(deleteShiftById)|(endOrder)|(modifyProducedPieces)|(modifyState)|(productTag)|(productTagString)|(recommendation)|(scrapCount)|(startOrder)|(state)|(uniqueProduct)|(scrapUniqueProduct))$
     - bidirectional: false
       name: HighThroughput
       send_direction: to_remote
       topic: ^ia\.(([^r.](\d|-|\w)*)|(r[b-z](\d|-|\w)*)|(ra[^w]))\.(\d|-|\w|_)+\.(\d|-|\w|_)+\.(process[V|v]alue).*$

   • If you have enabled Barcodereader, find the barcodereader section and set the following values, adding the missing ones and updating the already existing ones:

       pullPolicy: IfNotPresent
     resources:
       requests:
         cpu: "2m"
         memory: "30Mi"
       limits:
         cpu: "10m"
         memory: "60Mi"
     scanOnly: false # Debug mode, will not send data to kafka
