Prometheus operator Support AWS ALB to using ingress

[sangram23]

I have installed prometheus operator in my AWS EKS Cluster and trying to access using ingress . For Ingress Controller using AWS ALB.

1)- I have created Nodeport Service apiVersion: v1 kind: Service metadata: name: prometheus-server-nodeport labels: app: prometheus component: server release: prometheus spec: type: NodePort selector: app: prometheus component: server release: prometheus ports: - port: 80 targetPort: 9090

2)- Created ingress resource

apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: ingress-promethous labels: app: ingress-promethous annotations: #kubernetes.io/ingress.class: "alb" #(OLD INGRESS CLASS NOTATION - STILL WORKS BUT RECOMMENDED TO USE IngressClass Resource) #Ingress Core Settings #alb.ingress.kubernetes.io/scheme: internet-facing alb.ingress.kubernetes.io/scheme: internal #Health Check Settings alb.ingress.kubernetes.io/healthcheck-protocol: HTTP alb.ingress.kubernetes.io/healthcheck-port: traffic-port alb.ingress.kubernetes.io/healthcheck-path: /app1/index.html alb.ingress.kubernetes.io/healthcheck-interval-seconds: '15' alb.ingress.kubernetes.io/healthcheck-timeout-seconds: '5' alb.ingress.kubernetes.io/success-codes: '200' alb.ingress.kubernetes.io/healthy-threshold-count: '2' alb.ingress.kubernetes.io/unhealthy-threshold-count: '2' spec: ingressClassName: my-aws-ingress-class # Ingress Class rules:

• http: paths: - path: /app1 pathType: Prefix backend: service: name: prometheus-server-nodeport port: number: 80

Unable to get Promethous UI?

I prometheus support Ingress? or any Specific configuration need to do?

It should be possible to expose Prometheus via ingress and I'm not aware of any issue with AWS. Maybe check https://github.com/prometheus-operator/kube-prometheus/blob/main/docs/customizations/exposing-prometheus-alertmanager-grafana-ingress.md?

I can confirm, that its possible to use an ALB.

values.yaml for the helm chart:

prometheus:
  enabled: true
  ingress:
    annotations:
      alb.ingress.kubernetes.io/certificate-arn: >-
        arn:aws:acm:eu-central-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
      alb.ingress.kubernetes.io/group.name: prod-external
      alb.ingress.kubernetes.io/group.order: '10'
      alb.ingress.kubernetes.io/listen-ports: '[{"HTTPS": 443}]'
      alb.ingress.kubernetes.io/unhealthy-threshold-count: '3'
    enabled: true
    hosts:
      - prometheus.abc.loc
    labels: {}
    paths:
      - /
    tls:
      - hosts:
          - prometheus.abc.loc
        secretName: cert
  service:
    annotations: {}
    clusterIP: ''
    externalIPs: []
    labels: {}
    loadBalancerIP: ''
    loadBalancerSourceRanges: []
    nodePort: 30090
    port: 9090
    sessionAffinity: ''
    targetPort: 8081
    type: NodePort
