Ukubeka iliso postgres ngaphakathi Openshift

Molweni, bahlali bakwaHabr!

Namhlanje ndifuna ukukuxelela ukuba besifuna njani ukujonga ii-postgres kunye neqela lamanye amaziko ngaphakathi kweqela le-OpenShift kunye nendlela esiyenze ngayo.

Ekungeneni kwakukho:

• I-Openshift
• Helm
• Prometheus

Ukusebenza ngesicelo se-java, yonke into yayilula kwaye icacile, okanye ichaneke ngakumbi:

1) Ukongeza ku-build.gradle

 implementation "io.micrometer:micrometer-registry-prometheus"

2) Qhuba i-prometheus ngoqwalaselo

 - job_name: 'job-name'
    metrics_path: '/actuator/prometheus'
    scrape_interval: 5s
    kubernetes_sd_configs:
    - role: pod
      namespaces:
        names: 
          - 'name'

3) Ukongeza umboniso eGrafana

Yonke into yayilula kwaye i-prosaic de kwafika ixesha lokujonga iziseko ezikufutshane kwindawo yethu yamagama (ewe, oku kubi, akukho mntu wenza oku, kodwa kwenzeka izinto ezahlukeneyo).

Ingaba isebenza kanjani?

Ukongeza kwi-pod kunye ne-postgres kunye ne-prometheus ngokwayo, sifuna enye iqumrhu - umthengisi ngaphandle.

Umthumeli ngaphandle kwingqikelelo engabonakaliyo yiarhente eqokelela iimetrikhi ukusuka kwisicelo okanye nakwiseva. Kumthumeli we-postgres, kubhaliwe kwi-Go, isebenza kumgaqo wokusebenzisa izikripthi ze-SQL ngaphakathi kwedatha kwaye emva koko i-prometheus ithatha iziphumo ezifunyenweyo. Oku kukuvumela ukuba wandise iimetriki eziqokelelweyo ngokongeza eyakho.

Masiyisebenzise ngolu hlobo (umzekelo deployment.yaml, ukungabopheleli):

---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: postgres-exporter
  labels:
    app: {{ .Values.name }}
    monitoring: prometheus
spec:
  serviceName: {{ .Values.name }}
  replicas: 1
  revisionHistoryLimit: 5
  template:
    metadata:
      labels:
        app: postgres-exporter
        monitoring: prometheus
    spec:
      containers:
      - env:
        - name: DATA_SOURCE_URI
          value: postgresdb:5432/pstgr?sslmode=disable
        - name: DATA_SOURCE_USER
          value: postgres
        - name: DATA_SOURCE_PASS
          value: postgres
        resources:
          limits:
            cpu: 100m
            memory: 50Mi
          requests:
            cpu: 100m
            memory: 50Mi
        livenessProbe:
          tcpSocket:
            port: metrics
          initialDelaySeconds: 30
          periodSeconds: 30
        readinessProbe:
          tcpSocket:
            port: metrics
          initialDelaySeconds: 10
          periodSeconds: 30
        image: exporter
        name: postgres-exporter
        ports:
        - containerPort: 9187
          name: metrics

Ikwafuna inkonzo kunye ne-imagestream

Emva kokuthunyelwa, sifuna ngokwenene ukuba wonke umntu abonane.

Yongeza le nxalenye ilandelayo kwi-Prometheus config:

  - job_name: 'postgres_exporter'
    metrics_path: '/metrics'
    scrape_interval: 5s
    dns_sd_configs:
    - names:
      - 'postgres-exporter'
      type: 'A'
      port: 9187

Kwaye ke yonke into yasebenza, konke okuseleyo kukongeza yonke le nto kwigrafana kwaye ujabulele umphumo.

Ukongeza kwisakhono sokongeza eyakho imibuzo, unokutshintsha useto kwi-prometheus, uqokelele iimethrikhi ekujoliswe kuzo.

Oku kwenziwa ngendlela efanayo:

• Kafka
• Elasticsearch
• IMongo

PS Yonke idatha kumagama, amazibuko kunye nezinye zithathwa emoyeni kwaye aziqulathanga naluphi na ulwazi.
