部署

下载源码

wget https://github.com/prometheus-operator/kube-prometheus/archive/refs/tags/v0.13.0.zip

解压压缩包

unzip kube-prometheus-0.13.0.zip
cd kube-prometheus-0.13.0

Prometheus持久化

prometheus监控默认的监控数据存储方式为emptyDir，需要修改为NFS持久化存储。编辑manifests/prometheus-prometheus.yaml在文件末尾添加

spec:
  storage: #这部分为持久化配置
    volumeClaimTemplate:
      spec:
        storageClassName: nfs-provisioner
        accessModes: ["ReadWriteOnce"]
        resources:
          requests:
            storage: 10Gi

部署CRD自定义资源

kubectl apply --server-side -f manifests/setup/

部署监控

kubectl apply -f manifests/

执行部署之后会创建两个pvc，如下所示

NAME                                 STATUS   VOLUME                                     CAPACITY   ACCESS 
prometheus-k8s-db-prometheus-k8s-0   Bound    pvc-fe27bace-0c6e-4050-b252-37bd3656108c   10Gi       RWO     
prometheus-k8s-db-prometheus-k8s-1   Bound    pvc-3966e3c0-e536-471c-b13e-174e1102b490   10Gi       RWO     

检查Prometheus状态

kubectl -n monitoring get pod|grep prometheus-k8s
prometheus-k8s-0                       2/2     Running   0               4m22s
prometheus-k8s-1                       2/2     Running   0               4m22s

进入pod查看数据挂载目录

kubectl -n monitoring exec -it prometheus-k8s-0 -- sh
Defaulting container name to prometheus.
Use 'kubectl describe pod/prometheus-k8s-0 -n monitoring' to see all of the containers in this pod.
/prometheus $
/prometheus $ df -h|grep nfs
192.168.229.133:/nfs/monitoring-prometheus-k8s-db-prometheus-k8s-0-pvc-fe27bace-0c6e-4050-b252-37bd3656108c/prometheus-db
/prometheus $

grafana持久化

修改manifests/grafana-deployment.yaml中volumes.name.grafana-storage为以下内容

volumes:
- name: grafana-storage
  persistentVolumeClaim:
    claimName: grafana

创建pvc

cat > manifests/grafana-pvc.yaml <<EOF
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    k8s.kuboard.cn/pvcType: Dynamic
    pv.kubernetes.io/bind-completed: 'yes'
    pv.kubernetes.io/bound-by-controller: 'yes'
  name: grafana
  namespace: monitoring
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Gi
  storageClassName: nfs-provisioner
status:
  accessModes:
    - ReadWriteMany
  capacity:
    storage: 10Gi
EOF

创建grafana pvc

kubectl apply -f manifests/grafana-pvc.yaml

更新grafana deployment

kubectl apply -f manifests/grafana-deployment.yaml
