Spinnaker Ceph S3 Storage


Hello Guys,
i tried to deploy SPinnaker with Ceph S3 Storage, I followed the minio guide for the configuration ( without Region and custom endpoint) but I verified a strange behavior: during the deploy fase, front50 create bucket but not rootFolder and subfolder ( applications, project, pipeline, bla bla bla). My Ceph installation has one region ( zonegriup, zone - named default) and for the correct configuration of the clients I must not specified the name of region. Do you have experience to installation spinnaker with ceph S3 ? Could you help me to solve the problem? Thanks
