prometheus高可用部署命令

Prometheus 高可用部署需要使用 Prometheus 官方提供的命令行工具 `prometheus-operator`。具体操作步骤如下:

1. 安装 Prometheus Operator：

kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-x.x/bundle.yaml

2. 创建 Prometheus 配置文件：

apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
  name: prometheus
  labels:
    prometheus: prometheus
spec:
  replicas: 2 #副本数
  serviceAccountName: prometheus
  serviceMonitorSelector:
    matchLabels:
      prometheus: prometheus
  ruleSelector:
    matchLabels:
      prometheus: prometheus
  resources:
    requests:
      memory: 800Mi
  securityContext:
    fsGroup: 2000
  storage:
    class: standard
    size: 100Gi

3. 创建 Prometheus 实例：

kubectl apply -f prometheus.yaml

4. 创建 ServiceMonitor

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: example-servicemonitor
  labels:
    prometheus: prometheus
spec:
  selector:
    matchLabels:
      app: example
  endpoints:
  - interval: 30s
    path: /metrics
    port: web

5. 创建 ServiceMonitor

kubectl apply -f servicemonitor.yaml

这样就完成了 Prometheus 高可用部署。

注意: 请确保在部署过程中使用正确的 Kubernetes 版本以及 Prometheus 版本。
