如标题所示，我尝试在Digital Ocean托管的Kubernetes上运行Apache Druid。我在Minikube上本地运行了这个配置，并且运行良好，但是当我将集群切换到Digital Ocean时，在尝试创建/var/druid时，每个pod上都出现Access Denied错误。
服务：

apiVersion: v1
kind: Service
metadata:
  name: router
  labels:
    app: router
spec:
  ports:
    - port: 8888
  selector:

持续体积声明：

我对Druid和Kubernetes非常陌生，所以我肯定有些是不正确的，但是这项工作的范围实际上只是让配置工作，因为它在本地，在DO上。谷歌建议一些关于Druid版本是不正确的-很多关于Docker编写的问题。这些似乎都没有很大的帮助，因为它**工作在Minikube上，版本没有改变。
