• 安装kong

# 安装到默认default空间helm install kong kong/kong -f minimal-kong-standalone.yamlhelm upgrade kong kong/kong -f minimal-kong-standalone.yaml

• 安装konga。konga是UI库，调用kong-admin来管理kong https://github.com/pantsel/konga

apiVersion: apps/v1kind: Deploymentmetadata:  name: konga  labels:    app: kongaspec:  replicas: 1  selector:    matchLabels:      app: konga  template:    metadata:      labels:        app: konga    spec:      containers:      - env:        - name: DB_ADAPTER          value: postgres        - name: DB_URI          # kong-postgresql为service name          value: "postgresql://kong:Kong.=2021!@kong-postgresql:5432/konga_database"        image: pantsel/konga        imagePullPolicy: Always        name: konga        ports:        - containerPort: 1337          protocol: TCP      restartPolicy: Always---apiVersion: v1kind: Servicemetadata:  name: kongaspec:  ports:  - name: http    port: 1337    targetPort: 1337    protocol: TCP  selector:    app: konga---apiVersion: networking.k8s.io/v1kind: Ingressmetadata:  name: konga-ingress  annotations:    kubernetes.io/ingress.class: kongspec:  rules:  - host: konga.your_domain.com    http:      paths:      - path: /        pathType: ImplementationSpecific        backend:          service:            name: konga            port:              number: 1337

• konga运行后效果

• kong的prometheus监控。首先在konga中启用prometheus

• 安装prometheus的ServiceMonitor。prometheus安装参考 https://my.oschina.net/u/160697/blog/3197715

apiVersion: monitoring.coreos.com/v1kind: ServiceMonitormetadata:  name: prometheus-kong  # 需固定release: prometheus。默认创建的prometheus使用此标签来识别  labels:    release: prometheusspec:  # 不在同一命名空间，加上namespaceSelector  namespaceSelector:    matchNames:    - default  # 匹配的service的标签  selector:    matchLabels:      app.kubernetes.io/name: kong  endpoints:  # service中对应的端口名称  - port: kong-admin
