How To Setup Grafana On Kubernetes

Kubernetes is a powerful container orchestration platform used to automate the deployment, scaling, and management of containerized applications. Grafana, on the other hand, is an open-source platform used for data visualization and monitoring.

In this article, we will guide you through the process of setting up Grafana on Kubernetes.

Prerequisites:

Before we begin, make sure that you have the following prerequisites:

• A running Kubernetes cluster
• kubectl command-line tool installed
• Helm package manager installed

Installing Prometheus on Kubernetes:

Grafana relies on Prometheus for data collection and storage. Therefore, we need to install Prometheus first. Follow these steps to install Prometheus on Kubernetes:

1. Add the Prometheus Helm repository:
   

   helm repo add prometheus-community https://prometheus-community.github.io/helm-charts

2. Update the Helm repository:
   

   helm repo update

3. Install Prometheus using Helm:
   

   helm install prometheus prometheus-community/prometheus

4. Verify that Prometheus is running:
   

   kubectl port-forward service/prometheus-server 9090:80

   Open a web browser and go to http://localhost:9090. You should see the Prometheus web interface.

Installing Grafana on Kubernetes:

Now that we have installed Prometheus, we can proceed with installing Grafana on Kubernetes:

1. Add the Grafana Helm repository:
   

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

2. Update the Helm repository:
   

   helm repo update

3. Install Grafana using Helm:
   

   helm install grafana grafana/grafana

4. Verify that Grafana is running:
   

   kubectl port-forward service/grafana 3000:80

   Open a web browser and go to http://localhost:3000. You should see the Grafana login page.

Accessing Grafana Dashboard:

To access the Grafana dashboard, follow these steps:

1. Log in to Grafana using the default credentials:

   • Username: admin
   • Password: admin

2. You will be prompted to change the password. Enter a new password and click Save.

3. You will be redirected to the Grafana dashboard.

Adding a Prometheus Data Source:

To add a Prometheus data source to Grafana, follow these steps:

1. Click on the Configuration icon on the left menu and select Data Sources.

2. Click on the Add data source button.

3. Select Prometheus as the data source type.

4. Enter the URL of the Prometheus server in the URL field.

5. Click on the Save & Test button.

Creating a Grafana Dashboard:

To create a Grafana dashboard, follow these steps:

1. Click on the Create icon on the left menu and select Dashboard.

2. Click on the Add panel button.

3. Select the type of panel you want to add.

4. Configure the panel settings and data source.

5. Click on the Save button.

In this article, we have shown you how to set up Grafana on Kubernetes. We covered the installation of Prometheus, installation of Grafana, accessing the Grafana dashboard, adding a Prometheus data source, and creating a Grafana dashboard. With this knowledge, you can monitor your Kubernetes clusters with Grafana and keep track of your metrics.
