Using Prometheus#

Comment

We are about to deploy Prometheus for the first time. We won’t go into details behind the application except to say that it’s fantastic and that you should consider it for your monitoring and alerting needs. We’re using it only to demonstrate a few Kubernetes concepts. We’re not trying to learn how to operate it.

Looking into the definition

Let’s take a look at the application’s definition.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: prometheus
  annotations:
    kubernetes.io/ingress.class: "nginx"
    ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
spec:
  rules:
  - http:
      paths:
      - path: /prometheus
        pathType: ImplementationSpecific
        backend:
          service:
            name: prometheus
            port:
              number: 9090
---

apiVersion: apps/v1
kind: Deployment
metadata:
  name: prometheus
spec:
  selector:
    matchLabels:
      type: monitor
      service: prometheus
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        type: monitor
        service: prometheus
    spec:
      containers:
      - name: prometheus
        image: prom/prometheus:v2.0.0
        command:
        - /bin/prometheus
        args:
        - "--config.file=/etc/prometheus/prometheus.yml"
        - "--storage.tsdb.path=/prometheus"
        - "--web.console.libraries=/usr/share"
        - "--web.external-url=http://192.168.99.100/prometheus"
---

apiVersion: v1
kind: Service
metadata:
  name: prometheus
spec:
  ports:
  - port: 9090
  selector:
    type: monitor
    service: prometheus
