Grafana - k8s環境安裝部署grafana，測試正常，推薦使用！

 

這里有一個小問題，截圖中的name默認使Prometheus，我在這里需要改成prometheus，否則在導入dashboard的時候會報錯，‘not found the datasource Prometheus’ ;

 

    使用helm chart方式來創建grafana容器，在k8s環境中管理容器更加方便一些。  grafana-deployment.yaml : 

    首先要先准備好grafana的docker 鏡像：

    docker search grafana/grafana  ##查找公共的grafana docker 鏡像

    docker pull grafana/grafana       ##拉取想要的grafana的鏡像版本

    docker tag  grafana/grafana:latest docker.io/cpro/grafana-grafana:20210223    #將拉取到本地的grafana鏡像修改成我們自定義的名字（docker.io/cpro/grafana-grafana:20210223）

    使用kubectl create -f  grafana-deployment.yaml創建容器，使用下面命令查看部署的情況；

kubectl get deploy

kubectl get po

kubectl get svc
