Part 6: Observability stack setup to monitor

• How to monitor EKS cluster, Kubernetes components, and workloads using Prometheus and Grafana via HELM (on the master machine)

• Install Helm Chart

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh

• Add Helm Stable Charts for Your Local Client

helm repo add stable https://charts.helm.sh/stable

• Add Prometheus Helm Repository

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

• Create Prometheus Namespace

kubectl create namespace prometheus
kubectl get ns

• Install Prometheus using Helm

helm install stable prometheus-community/kube-prometheus-stack -n prometheus

• Verify Prometheus installation

kubectl get pods -n prometheus

• Check the services file (svc) of the Prometheus

kubectl get svc -n prometheus

• Expose Prometheus and Grafana to the external world through Node Port

[Note] change it from Cluster IP to NodePort after changing make sure you save the file and open the assigned nodeport to the service.

kubectl edit svc/stable-kube-prometheus-sta-prometheus -n prometheus

Verify service

kubectl get svc -n prometheus

• Now, let’s change the SVC file of Grafana and expose it to the outer world

kubectl edit svc stable-grafana -n prometheus

• Check the Grafana service

kubectl get svc -n prometheus

• Access the Grafana with <public-ip-of-master>:32108 and Prometheus with <public-ip-of-master>:31521

Note - First port-forward through the below command:

kubectl port-forward svc/stable-grafana 32108:80 -n prometheus --address 0.0.0.0 &

kubectl port-forward svc/stable-kube-prometheus-sta-prometheus 31521:9090 -n prometheus --address 0.0.0.0 &

• Prometheus:

• Get a password for Grafana

[Note] Username: admin

kubectl get secret --namespace prometheus stable-grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

• Now, view the Dashboard in Grafana

• Click on Dashboards

• Put the Data Source: Prometheus and Namespace: wanderlust and run for the last 5 minutes.

• Custom dashboard by searching on google.com

• Select anything you liked! and copy the ID

• Import

Finish!!!

If you managed to follow all the parts and implemented all the steps sucessfully then it's time to celebrate because its most demanding skills in Market
