如何在kubernetes中安装grafana插件？

我正在kubernetes集群（v1.15.2）中部署grafana（6.6.0），现在我想在grafana中安装饼图插件。当我不在docker中时，我可以使用此命令安装：

grafana-cli plugins install grafana-piechart-panel

但是现在我在kubernetes集群中，我可以登录到pod并运行install命令，但是当pod被销毁并重新创建时，安装历史就丢失了。我应该如何在kubernetes集群grafana中永久安装插件？我曾尝试在yaml中这样定义：

"name": "grafana",
            "image": "grafana/grafana:6.6.0",
            "ports": [
              {
                "name": "http",
                "containerPort": 3000,
                "protocol": "TCP"
              }
            ],
            "env": [
              {
                "name": "GF_INSTALL_PLUGINS",
                "value": "grafana-piechart-panel"
              }
            ],

对我来说不起作用。

添加环境变量

GF\u INSTALL\u PLUGINS=grafana piechart panel，grafana clock panel

将在容器世界为您安装插件

请参阅的最新版本中的插件列表，插件列表可以在中作为列表传递

使用永久磁盘并装入/var/lib/grafana。 插件位于/var/lib/grafana/Plugins中。

容器重新启动后，数据将保持不变。
