Grafana on EKS

We assume you already have an EKS cluster running, if you don't please refer to this article to create a cluster on EKS.

Setup grafana on EKS

Create a file named grafana-datasource-config.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: grafana-datasources
  namespace: monitoring
data:
  prometheus.yaml: |-
    {
        "apiVersion": 1,
        "datasources": [
            {
               "access":"proxy",
                "editable": true,
                "name": "prometheus",
                "orgId": 1,
                "type": "prometheus",
                "url": "http://prometheus-service.monitoring.svc:8080",
                "version": 1
            }
        ]
    }

Create the configmap using the following command.

kubectl create -f grafana-datasource-config.yaml

Create a file name deployment.yaml

Add the following contents to that

apiVersion: apps/v1
kind: Deployment
metadata:
  name: grafana
  namespace: monitoring
spec:
  replicas: 1
  selector:
    matchLabels:
      app: grafana
  template:
    metadata:
      name: grafana
      labels:
        app: grafana
    spec:
      containers:
      - name: grafana
        image: grafana/grafana:latest
        ports:
        - name: grafana
          containerPort: 3000
        resources:
          limits:
            memory: "1Gi"
            cpu: "1000m"
          requests: 
            memory: 500M
            cpu: "500m"
        volumeMounts:
          - mountPath: /var/lib/grafana
            name: grafana-storage
          - mountPath: /etc/grafana/provisioning/datasources
            name: grafana-datasources
            readOnly: false
      volumes:
        - name: grafana-storage
          emptyDir: {}
        - name: grafana-datasources
          configMap:
              defaultMode: 420
              name: grafana-datasources

Note: This Grafana deployment does not use a persistent volume. If you restart the pod all changes will be gone. Use a persistent volume if you are deploying Grafana for your project requirements. It will persist all the configs and data that Grafana uses.

Create the deployment

kubectl create -f deployment.yaml

Create a file name service.yaml.

Add the following contents to it.

apiVersion: v1
kind: Service
metadata:
  name: grafana
  namespace: monitoring
  annotations:
      prometheus.io/scrape: 'true'
      prometheus.io/port:   '3000'
spec:
  selector: 
    app: grafana
  type: NodePort  
  ports:
    - port: 3000
      targetPort: 3000
      nodePort: 32000

Create the service using the following command:

kubectl create -f service.yaml

Now you should be able to access the Grafana dashboard using any node IP on port 32000. Make sure the port is allowed in the firewall to be accessed from your workstation.

http://<your-node-ip>:32000

You can also use kubectl port forward to do the same:

kubectl port-forward -n monitoring <grafana-pod-name> 3000 &

Use the below credentials when you see the Grafana dashboard:

User: admin
Pass: admin

Change the admin password.

Add a new dashboard and data source as Prometheus. You can further customize grafana as per your needs but the basic setup is done.

Thank you, we have successfully configured Grafana for EKS.

Note: This is not a production-ready setup. For production, more configurations are needed.
