Configure Ingress for Prometheus and Grafana

Description

Ingress resources allow you to expose services within your cluster using URLs. Below are Ingress configurations for Prometheus and Grafana.

1.1 Create Ingress Resource for Prometheus

Save the following YAML as prometheus-ingress.yaml:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: prometheus-igrs
  namespace: monitoring
  labels:
    app: prometheus
spec:
  rules:
  - host: prometheus.local
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: prometheus-server
            port:
              number: 80
 

1.2 Create Ingress Resource for Grafana

Save the following YAML as grafana-ingress.yaml:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: grafana-igrs
  namespace: monitoring
  labels:
    app: grafana
spec:
  rules:
  - host: grafana.local
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: grafana
            port:
              number: 80
 

Apply the Ingress Files

Apply the Ingress resources using kubectl:

kubectl apply -f grafana-ingress.yaml
kubectl apply -f prometheus-ingress.yaml

Step 2: Update /etc/hosts (Optional for Local Access)

To access Prometheus and Grafana via their hostnames (prometheus.local and grafana.local), add entries to your local /etc/hosts file, pointing them to your cluster’s IP address.

Example entry:

<host_ip> prometheus.local grafana.local

These configurations should make Prometheus available at http://prometheus.local and Grafana at http://grafana.local. Make sure that your Ingress controller is set up and configured in your cluster to handle these resources.
