Add Helm repository

• To use the HiveMQ Kubernetes Operator to deploy and manage your HiveMQ cluster on the Kubernetes nodes, you need to add the HiveMQ Helm repository to your Helm installation:

helm repo add hivemq https://hivemq.github.io/helm-charts

helm repo update

• Download the values.yaml file and open it in a code editor of your choice( we use VSCode). This file will be modified for configuration changes in the future

helm show values hivemq/hivemq-operator > values.yaml

...

• nodecount: 3

• cpu: "4"

• memory: "4Gi"

• ephemeralStorage: "15Gi"

Apply the changes to the cluster

helm upgrade hivemq --install hivemq/hivemq-operator --values values.yaml

Verify if the HiveMQ Cluster is running successfully

Please make sure that pods are running successfully after the change, it may take some time for the pods to be ready
