1. 系统要求

最小化的软硬件要求

最小化硬件要求

• 磁盘空间: 1 GB
• 内存: 750 MiB (approx 750 MB)
• CPU: 250m (approx 2.5 cores)

2. k8s部署grafana步骤

1) 创建名字空间

kubectl create namespace my-grafana

 2) 创建yaml

vim  grafana.yaml

 yaml包含如下三个资源对象

Object	Description
Persistent Volume Claim (PVC)	存储声明
Service	提供pod的网络访问
Deployment	负责创建pod，并确保可以滚动更新和管理副本集

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: grafana-pvc

---
apiVersion: apps/v1

 3) 执行yaml

这里并没有创建pv，所以要确保有可用的pv使用(至少要有1Gi的pv可用)，才可以执行如下的命令

kubectl apply -f grafana.yaml --namespace=my-grafana

 4) 查看结果

kubectl get pv,pvc,deployment -n my-grafana

 

 5) 访问grafana

kubectl get svc -n my-grafana

grafana的service采用的是NodePort方式暴露服务，因此可以通过映射的随机端口31483进行访问：

 

 这里k8s部署grafana就算成功了
