EKS-Prometheus-Grafana
Deploy Prometheus monitoring and Grafana Dashboards on an EKS cluster using Terraform and Helm.
- Docker
- AWS user with programmatic access and high privileges
- Linux terminal
- Deploy an EKS K8 Cluster with Self managed Worker nodes on AWS using Terraform.
- Deploy a NGINX Ingress on the above EKS cluster (Pod->service->Ingress->ELB+ACM->Route 53->Domain URL)
- Deploy a Cluster Autoscaler on the above EKS cluster using Terraform and Helm
- Clone the repository
- Set environment variable TF_VAR_AWS_PROFILE
- Review terraform variable values in variables.tf, locals.tf
- Override values in the Helm chart through the "chart_values.yaml" file
- Update the "adminPassword:" attribute with a value, in the grafana section of "chart_values.yaml" file
- Update kubernetes.tf with the AWS S3 bucket name and key name from the output of the EKS K8 Cluster
- Configure AWS user with AWS CLI.
docker-compose run --rm aws configure --profile $TF_VAR_AWS_PROFILE
docker-compose run --rm aws sts get-caller-identity
- Specify appropriate Terraform workspace.
docker-compose run --rm terraform workspace show
docker-compose run --rm terraform workspace select default
- Run Terraform apply to create the EKS cluster, k8 worker nodes and related AWS resources.
./run-docker-compose.sh terraform init
./run-docker-compose.sh terraform validate
./run-docker-compose.sh terraform plan
./run-docker-compose.sh terraform apply
- Verify prom and grafana related deployments, pods and services are running and the Ingress is setup correctly.
./run-docker-compose.sh kubectl get all -A | grep -i monitoring
./run-docker-compose.sh kubectl get ingress -n monitoring
- View the Grafana application URL using the Domain Https URL, prefixed by "grafana." and when prompted, enter grafana admin username and password.
- Grafana ingress is not connected to the AWS Network load balancer.
Issue: The external address field on the ingress remains empty. ideally, it is expected to list the NLB Domain address.
Fix: Added the below assignment under the Ingress section of grafana service in the helm chart_values.yaml
ingressClassName: nginx
