In this article, we will walk you through the steps to set or update the Grafana admin password in a Kubernetes cluster using the HiveMQ Operator. By default, the admin password for Grafana is set to "prom-operator." However, it is recommended to change this password for security purposes. We will also cover how to confirm the changes by logging into the Grafana dashboard.

Prerequisites

  • The Kubernetes cluster is already set up and running.

  • k8s version 1.16+ is installed

  • Helm version 3 is installed

  • The Hivemq k8s operator repo is already added in the helm repo

 Instructions

  1. Add the kube-prometheus-stack config block in your values.yaml to set Grafana admin password. Please refer following example.

    kube-prometheus-stack: grafana: adminPassword: "set your password here" hivemq: monitoring: enabled: true dedicated: true ...

  2. Deploy the changes using the following command

    helm upgrade --install -f <your values.yaml> <your deployment name> hivemq/hivemq-operator -n <namespace>

  3. That’s it. You can confirm the changes by login to the grafana dashboard.
