Add the Prometheus community Helm repository and update it:

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

Create a custom-values.yaml file to customize the Helm chart installation. This file will configure Prometheus and Grafana to be exposed via NodePorts.

# custom-values.yaml
prometheus:
  service:
    type: NodePort
grafana:
  service:
    type: NodePort

Then, install the kube-prometheus-stack using Helm:

helm upgrade --install kube-prometheus-stack prometheus-community/kube-prometheus-stack -f custom-values.yaml

kubectl --namespace default get pods -l "release=kube-prometheus-stack"
