kubernetes1.18.8|kubernetes1.18.8 安装kube-prometheus kubernetes1.18.8安装kube-prometheus

kube-prometheus 是一整套监控解决方案，它使用 Prometheus 采集集群指标，Grafana 做展示，包含如下组件：

The Prometheus Operator
Highly available Prometheus
Highly available Alertmanager
Prometheus node-exporter
Prometheus Adapter for Kubernetes Metrics APIs （k8s-prometheus-adapter）
kube-state-metrics
Grafana

其中 k8s-prometheus-adapter使用 Prometheus 实现了 metrics.k8s.io和 custom.metrics.k8s.io API，所以不需要再部署 metrics-server。

#修改service类型为NodePort prometheus service

$ cat prometheus-service.yaml apiVersion: v1 kind: Service metadata: labels: prometheus: k8s name: prometheus-k8s namespace: monitoring spec: type: NodePort ports: - name: web port: 9090 targetPort: web nodePort: 30090 selector: app: prometheus prometheus: k8s sessionAffinity: ClientIP

alertmanager service

$ cat alertmanager-service.yaml apiVersion: v1 kind: Service metadata: labels: alertmanager: main name: alertmanager-main namespace: monitoring spec: type: NodePort ports: - name: web port: 9093 targetPort: web nodePort: 30093 selector: alertmanager: main app: alertmanager sessionAffinity: ClientIP

grafana service

$ cat grafana-service.yaml apiVersion: v1 kind: Service metadata: labels: app: grafana name: grafana namespace: monitoring spec: type: NodePort ports: - name: http port: 3000 targetPort: http nodePort: 32000 selector: app: grafana
