I’m currently working on a project where Rancher is used with Ceph block/file and object storage.
All are working fine. For the rbd (block storage) i was able to get it working with the native ‘rbd’ kernel module so that i can provision block images on ceph without using the out-of-tree provisioner (https://github.com/kubernetes-incubator/external-storage/tree/master/ceph/rbd).
For CephFS i’m currently using the external provisioner (https://github.com/kubernetes-incubator/external-storage/tree/master/ceph/cephfs) which works as expected, however it would be nice if i could use also built-in support for CephFS… is this supported on Rancher? I tried to load the ceph/libceph ‘module’ but this doesn’t work…
