一、下载普罗米修斯配置清单

1.查看集群状态

[root@k8s-m-01 ~]# kubectl get nodes
NAME       STATUS   ROLES                  AGE   VERSION
k8s-m-01   Ready    control-plane,master   22d   v1.21.3
k8s-n-01   Ready    <none>                 22d   v1.21.3
k8s-n-02   Ready    <none>                 22d   v1.21.3

2.下载代码

[root@k8s-master-01 ~]# git clone -b release-0.7 --single-branch https://github.com/prometheus-operator/kube-prometheus.git
 
# 或者
[root@k8s-master-01 ~]# wget https://github.com/prometheus-operator/kube-prometheus/archive/refs/tags/v0.7.0.tar.gz

3.解压

[root@k8s-master-01 ~]# tar xf kube-prometheus-0.7.0.tar.gz

4.部署

[root@k8s-m-01 ~]# cd kube-prometheus-0.7.0/manifests/setup/
[root@k8s-m-01 setup]# kubectl apply -f ./

#查看
[root@k8s-m-01 setup]# kubectl get pod -n monitoring
prometheus-operator-7649c7454f-6rcdd   2/2     Running            0          16m
[root@k8s-m-01 setup]# cd ..
[root@k8s-m-01 manifests]# pwd
/root/kube-prometheus-0.7.0/manifests

[root@k8s-m-01 manifests]# kubectl apply -f ./

#如果要卸载，先卸载manifests这个目录，再卸载setup，顺序不能搞反，会导致命名空间锁死

#如果拉取镜像失败，可以加谷歌的DNS
[root@k8s-m-01 manifests]# vim /etc/resolv.conf 
# Generated by NetworkManager
nameserver 114.114.114.114
nameserver 8.8.8.8
~              

5.创建ingress域名

[root@k8s-m-01 manifests]# mkdir ingress
[root@k8s-m-01 manifests]# cd ingress/
[root@k8s-m-01 ingress]# cat ingress.yaml 
kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
  name: prometheus
  namespace: monitoring
spec:
  rules:
    - host: "prometheus.test.com"
      http:
        paths:
          - path: "/"
            pathType: Prefix
            backend:
              service:
                name: prometheus-k8s
                port:
                  number: 9090
---
kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
  name: grafana
  namespace: monitoring
spec:
  rules:
    - host: "grafana.test.com"
      http:
        paths:
          - path: "/"
            pathType: Prefix
            backend:
              service:
                name: grafana
                port:
                  number: 3000

 
# 启动
[root@k8s-m-01 ingress]# kubectl apply -f ingress.yaml
ingress.networking.k8s.io/prometheus created
ingress.networking.k8s.io/grafana created

6.查看本机映射端口

[root@k8s-m-01 ingress]# kubectl get svc -n ingress-nginx 
NAME                                 TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
ingress-nginx-controller             NodePort    10.108.202.150   <none>        80:31197/TCP,443:30826/TCP   12d
ingress-nginx-controller-admission   ClusterIP   10.97.217.170    <none>        443/TCP                      12d

7.配置本地hosts解析

192.168.15.31 linux.alert.com linux.grafana.com linux.prometheus.com

8.访问

linux.alert.com:31197
linux.grafana.com:31197
linux.prometheus.com:31197

二、检查grafana出图

1.登录

2.检查
