Ukuqapha ama-postgres ngaphakathi kwe-Openshift

Sanibonani bahlali baseHabr!

Namuhla ngifuna ukukutshela ukuthi besifuna kanjani ukuqapha ama-postgres nezinye izinhlangano ezimbalwa ngaphakathi kweqoqo le-OpenShift nokuthi sikwenze kanjani.

Ekungeneni babephethe:

• I-Openshift
• Helm
• Prometheus

Ukusebenza ngohlelo lwe-java, yonke into ibilula futhi isobala, noma ukunemba kakhudlwana:

1) Ukungeza ku-build.gradle

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

2) Qalisa i-prometheus ngokucushwa

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

3) Ukwengeza isibonisi ku-Grafana

Yonke into yayilula futhi i-prosaic kwaze kwafika isikhathi sokuqapha izisekelo eziseduze nendawo yethu yamagama (yebo, lokhu kubi, akekho owenza lokhu, kodwa kwenzeka izinto ezahlukene).

Isebenza kanjani?

Ngaphezu kwe-pod ene-postgres kanye ne-prometheus ngokwayo, sidinga enye inhlangano - isithekelisi.

Umthumeli ngaphandle kumqondo ongabonakali umenzeli oqoqa amamethrikhi kusuka kuhlelo lokusebenza noma iseva. Kumthumeli we-postgres, kubhalwe ku-Go, kusebenza kumgomo wokusebenzisa imibhalo ye-SQL ngaphakathi kwedathabhesi bese u-prometheus ethatha imiphumela etholiwe. Lokhu futhi kukuvumela ukuthi unwebe ama-metrics aqoqiwe ngokungeza awakho.

Masiyisebenzise kanje (isibonelo i-deployment.yaml, engabophezeli):

---
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

Iphinde yadinga isevisi nokusakaza kwesithombe

Ngemuva kokuthunyelwa, sifuna ngempela ukuthi wonke umuntu abonane.

Engeza ucezu olulandelayo ku-Prometheus config:

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

Futhi-ke konke kwasebenza, okusele nje ukufaka zonke lezi zinto ku-grafana futhi ujabulele umphumela.

Ngokungeziwe ekhonweni lokwengeza eyakho imibuzo, ungashintsha izilungiselelo ku-prometheus, uqoqe amamethrikhi amaningi ahlosiwe.

Lokhu kwenziwa ngendlela efanayo:

• KAFKA
• Islastiki
• Mongo

PS Yonke imininingwane yamagama, amachweba nokunye ithathwa emoyeni futhi ayiqukethe noma yiluphi ulwazi.
