In AWS, installing Prometheus-stack and enabling HTTPS in Grafana

aws-eks-prometheus-stack-installation.md

Subject

• How to install a Prometheus-stack in AWS EKS
• configure with
  • persistent volume (AWS EBS)
  • load balancer with HTTPS (AWS ELB)

Prerequisites

• Running an AWS EKS
• A certificate created at ACM
• EBS CSI driver installation in the EKS
• A customization file that has values to override in the prometheus-stack chart

Customization File (name : custom.yaml)

When you create a file, you should set your certificate in ${ACM_CERT_ARN} and would adjust suitably resources, storage size, etc.

Installation

# Add the prometheus chart repository.
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update

# Create a namespace where components will be in.
# In this guide, we will use the namespace named monitoring.
kubectl create ns monitoring

# Install with customized values like above.
helm install prometheus-stack prometheus-community/kube-prometheus-stack -f ./custom.yaml -n monitoring

# Inspect the installed release.
kubectl get pods -l "release=prometheus-stack" -n monitoring
helm get values prometheus-stack -n monitoring
kubectl get pvc -n monitoring
kubectl get pv -n monitoring
