Install Prometheus on AWS EKS using Helm

  • Create Namespace for Prometheus 

                        
kubectl create ns prometheus

  • Persistent Storage

    We'll store Prometheus data on AWS EBS as persistent storage, for that create we'll create storage class and persitent volument claim. We need to create 2 SC and PVC for 2 different component of Prometheus - Server and AlertManager.

    StorageClass - AlertManager

                        
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: prometheus-alertmanager
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  fsType: ext4
allowVolumeExpansion: true

    StorageClass - Server

                        
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: prometheus-server
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  fsType: ext4
allowVolumeExpansion: true

    Persistent Volume Claim - AlertManager

                        
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: prometheus-alertmanager
  namespace: prometheus
  labels:
    app: prometheus-alertmanager
spec:
  storageClassName: prometheus-alertmanager
  resources:
    requests:
      storage: 50Gi
  accessModes:
    - ReadWriteOnce

    Persistent Volume Claim - Server

                        
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: prometheus-server
  namespace: prometheus
  labels:
    app: prometheus-server
spec:
  storageClassName: prometheus-server
  resources:
    requests:
      storage: 50Gi
  accessModes:
    - ReadWriteOnce
  • Install using Helm

    In this command we've set few values like

    namespace, service type, storageclass, PVC and its size as created in previous type 
                            
helm install prometheus stable/prometheus \
--namespace prometheus \
--set alertmanager.persistentVolume.storageClass="prometheus-alertmanager",server.persistentVolume.storageClass="prometheus-server",alertmanager.persistentVolume.existingClaim="prometheus-alertmanager", server.persistentVolume.existingClaim="prometheus-server",server.service.type="LoadBalancer"
  • Verify the installation 
                        
helm list -n prometheus
kubectl get sc -n prometheus
kubectl get po -n prometheus
kubectl get svc -n prometheus
