清理镜像方便后面一次性上传

docker rmi `docker images | grep -v REPOSITORY | awk '{print $1":"$2}'`

 部署项目  使用yml文件helm安装

vim prometheus-values.yaml

alertmanager:
  alertmanagerSpec:
    image:
      repository: prometheus/alertmanager
      tag: v0.24.0
grafana:
  enabled: true

prometheus:
  service:
    type: LoadBalancer
  prometheusSpec:
    image:
      repository: prometheus/prometheus
      tag: v2.37.0

创建namespace

kubectl create namespace monitoring

安装：

helm  -n monitoring install kube-prometheus-stack -f yml/prometheus-values.yaml kube-prometheus-stack-39.11.0.tgz
helm -n monitoring get manifest kube-prometheus-stack |kubectl get -f  -

 访问：

在import里边加载13105模板汉化 

二、 部署nginx监控实例

上传对应版本所需要的镜像：  exporter监控

docker pull bitnami/nginx-exporter:0.11.0-debian-11-r369

修改chart包配置文件：

使用oci 上传 

helm install myapp oci://reg.westos.org/charts/nginx

vim prometheus-adapter-values.yaml

image:
  repository: prometheus/prometheus-adapter
  tag: v0.10.0
prometheus:
  url: http://kube-prometheus-stack-prometheus.monitoring.svc

helm -n monitoring install prometheus-adapter -f yml/prometheus-adapter-values.yaml prometheus-adapter-3.4.0.tgz

kubectl delete hpa --all

vim nginx-hpa.yaml

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
  name: myapp-nginx
  namespace: default
spec:
  minReplicas: 1
  maxReplicas: 10
  metrics:
  - type: Pods
    pods:
      metric:
        name: nginx_http_requests
      target:
        type: AverageValue
        averageValue: 10
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: myapp-nginx
kubectl apply -f nginx-hpa.yaml

mv hey  /usr/local/bin/
chmod +x /usr/local/bin/hey
