Can I use my S3 bucket with a Kubernetes cluster created on Apiculus CloudConsole?

Yes, if the S3 bucket has been created using the Apiculus S3 Service, you can use the CSI (container storage interface) plugin maintained by Cloudian. If you're using a hyperscaler S3 service or a ceph cluster, you can use the CSI maintained by the hyperscaler (or ceph) with your Kubernetes cluster created on Apiculus CloudConsole.
