prometheus-operator中的grafana如何离线安装plugins

生产环境中grafana的数据在做持久化,以grafana-piechart-panel为例如：

• 下载离线插件

wget -nv https://grafana.com/api/plugins/grafana-piechart-panel/versions/latest/download -O /tmp/grafana-piechart-panel.zip

• 把插件copy进容器中

kubectl cp /tmp/grafana-piechart-panel.zip -n monitor  prometheus-grafana-xxxxxx:/var/lib/grafana/plugins -c grafana

• 进入容量，并把插件解压到目录下

kubectl exec -it -n monitor  prometheus-grafana-xxxxxx -c grafana -- sh
cd  /var/lib/grafana/plugins
unzip grafana-piechart-panel.zip

• 重启grafana

kubectl delete pod -n monitoring prometheus-grafana-xxxxxx
