\uD83D\uDCD8 Instructions

1. Clone the repo with hivemq-operator charts locallyGet a local copy of the Helm chart.
   This will create a local copy of the charts saved to the helm-charts subdirectory.download the chart of the version $CHART_VERSION and untar it to the subdirectory hivemq-operator:

   Code Block
   language bash
   githelm clone https://github.compull hivemq/hivemq/helm-charts.git

   Code Block
   language bash
   tree -L 1 . └── helm-charts

   Update dependencies

   -operator --version $CHART_VERSION --untar

2. Update dependencies in the chart’s directory.
   This command verifies that the required charts, as expressed in 'Chart.yaml', are present in 'charts/' and are at an acceptable version. It will pull down the latest charts that satisfy the dependencies, and clean up old dependencies.

   Code Block
   language bash
   helm dependencies update helm-charts/charts/hivemq-operator

3. Edit operator templates, and update the livenessProbe’s declaration.

   1. Edit the operator templates:

      1. helm-charts/charts/hivemq-operator/operator-tmpls/cluster-daemon-set.yamlhelm-charts/

      2. charts/hivemq-operator/operator-tmpls/cluster-deployment.yaml

      3. helm-charts/charts/hivemq-operator/operator-tmpls/cluster-stateful-set.yaml

   2. Find the existing declaration of the livenessProbe:

      Code Block
      language yaml
      livenessProbe: tcpSocket: port: {{ util:getPort(spec, "mqtt").port }} initialDelaySeconds: 15 periodSeconds: 30 failureThreshold: 240

   3. Replace with the new declaration of the livenessProbe:

      Code Block
      language yaml
      livenessProbe: httpGet: path: /heartbeat port: {{ util:getPort(spec, "heartbeat").port }} initialDelaySeconds: 30 periodSeconds: 15 failureThreshold: 240

4. Get the values.yaml file for the hivemq-operator of the version $CHART_VERSION:

   Code Block
   language bash
   helm show values hivemq/hivemq-operator --version $CHART_VERSION > my-values.yaml

5. Edit the my-values.yaml file:

   1. Add the heartbeat extension to the end of the hivemq.extensions array:

      Code Block
      language yaml
      hivemq: ... extensions: ... ... - name: hivemq-heartbeat-extension extensionUri: https://github.com/hivemq/hivemq-heartbeat-extension/releases/download/1.0.4/hivemq-heartbeat-extension-1.0.4.zip enabled: true

   2. Add the heartbeat port to the end of the hivemq.ports array:

      Code Block
      language yaml
      hivemq: ... ports: ... ... - name: "heartbeat" port: 9090 expose: true

6. Using Helm, install hivemq-operator from the local directory which is containing updated operator templates and use the updated my-values.yaml:

   Code Block
   language bash
   helm upgrade my-hivemq \ --install helm-charts/charts/hivemq-operator \ --values my-values.yaml

7. When the hivemq-operator and hivemq pods are ready, monitor the event.log:

   Code Block
   language bash
   kubectl exec pod/my-hivemq-abcdefgh -- tail -f log/event.log
