前言

在k8s集群中，使用ingress服务转发grafana的页面。

---

一、思路

ingress方面增加路由规则和跨命名空间的service即可
grafana增加configmap挂载grafana.ini文件，增加匿名登陆配置和root_url配置

二、grafana准备

1. grafana-configmap.yaml

grafana.ini文件的yaml文件

apiVersion: v1
kind: Namespace
metadata:name: grafana
---
apiVersion: v1
kind: ConfigMap
metadata:name: grafanaininamespace: grafana
data:grafana.ini: |[server]domain: daxinxindahaohao.cnroot_url: http://daxinxindahaohao.cn/grafanaserve_from_sub_path: true[auth.anonymous]enabled: trueorg_role: Viewer

2. grafana.yaml

grafana启动服务的yaml文件
我这里使用的pvc的存储类型是rook-ceph，使用其他存储类型的修改为自己的就可以

apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: grafana-pvcnamespace: grafana
spec:storageClassName: rook-cephfsaccessModes:- ReadWriteOnceresources:requests:storage: 50G
---
apiVersion: apps/v1
kind: Deployment

apiVersion: v1
kind: Service
metadata:name: grafananamespace: grafana
spec:ports:- port: 3000protocol: TCPtargetPort: http-grafanaselector:app: grafanasessionAffinity: Nonetype: ClusterIP

三、ingress准备

1. ingress.yaml

apiVersion: v1
kind: Namespace
metadata:name: daxinxindahaohao
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:name: daxinxindahaohao-ingress    #ingress名称namespace: daxinxindahaohao       #这里写ingress服务运行所在的命名空间名称annotations:kubernetes.io/ingress.class: "nginx"
spec:rules:- host: daxinxindahaohao.cn     #设置域名http:paths:- path: /grafanapathType: Prefix    # 前缀匹配backend:service:name: grafanaport:number: 3000

2. grafana-externalname.yaml

这里配置的是grafana的跨命名空间的service

kind: Service
apiVersion: v1
metadata:name: grafananamespace: daxinxindahaohao
spec:type: ExternalNameexternalName: grafana.grafana.svc.cluster.local

3. ingress-nginx-controller

端口是31247，下面会用到

四、 本机host文件准备

路径 C:\Windows\System32\drivers\etc\hosts

五、访问测试

通过浏览器进行访问测试
地址是：http://daxinxindahaohao.cn:31247/grafana
