### 创建命名空间
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
kubectl create ns monitor
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 创建PVC
|
|||
|
|
|
|||
|
|
```yaml
|
|||
|
|
apiVersion: v1
|
|||
|
|
kind: PersistentVolumeClaim
|
|||
|
|
metadata:
|
|||
|
|
name: grafana-pvc
|
|||
|
|
namespace: monitor
|
|||
|
|
spec:
|
|||
|
|
storageClassName: nfs-client
|
|||
|
|
accessModes:
|
|||
|
|
- ReadWriteOnce
|
|||
|
|
resources:
|
|||
|
|

|
|||
|
|
storage: 10Gi
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|

|

|
|
|
|||
|
|
- 准备grafana.ini 配置文件
|
|||
|
|
- 可以先不挂载grafana配置文件部署，然后去pod里边查看需要的配置内容在新建ini文件
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
kubectl create configmap grafana-config --from-file=grafana.ini --namespace=monitor
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 创建Deployment
|

### 创建Service
|
|||
|
|
|
|||
|
|
- ClusterIP 模式，也可以NodePort或LoadBalancer模式，我用ingress，所以使用的ClusterIP模式
|
|||
|
|
|
|||
|
|
```yaml
|
|||
|
|
apiVersion: v1
|
|||
|
|
kind: Service
|
|||
|
|
metadata:
|
|||
|
|
name: grafana
|
|||
|
|
namespace: monitor
|
|||
|
|
spec:
|
|||
|
|
ports:
|
|||
|
|
- port: 3000
|
|||
|
|
protocol: TCP
|
|||
|
|
targetPort: http-grafana
|
|||
|
|
selector:
|
|||
|
|
app: grafana
|
|||
|
|
sessionAffinity: None
|
|||
|
|
type: ClusterIP
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 创建Ingress基于trafik
|
|||
|
|
|
|||
|
|
```yaml
|
|||
|
|
apiVersion: networking.k8s.io/v1
|
|||
|
|
kind: Ingress
|
|||
|
|
metadata:
|
|||
|
|
name: kubepi-traefik-ingress
|
|||
|
|
namespace: monitor
|
|||
|
|
annotations:
|
|||
|
|
traefik.ingress.kubernetes.io/router.entrypoints: web
|
|||
|
|
spec:
|
|||
|
|
ingressClassName: "traefik"
|
|||
|
|
rules:
|
|||
|
|
- host: home.heysq.com
|
|||
|
|
http:
|
|||
|
|
paths:
|
|||
|
|
- backend:
|
|||
|
|
service:
|
|||
|
|
name: grafana
|
|||
|
|
port:
|
|||
|
|
number: 3000
|
|||
|
|
path: /grafana
|
|||
|
|
pathType: Prefix
|
|||
|
|
|
|||
|
|
```
