I want use k8s storageclass under coreos, but failed
.CoreOS version is stable (1122.2) .Hyperkube version is v1.4.3_coreos.0
k8s cluster deployed by coreos-kubernetes script , and modify rkt_opts for rbd recommandded by kubelet-wrapper.md
ceph version is jewel, I have mounted a rbd image on coreos , it works well.
now, I try to use pvc in pods, Refer to the kubernetes official document https://github.com/kubernetes/kubernetes/tree/master/examples/experimental/persistent-volume-provisioning
the config files:
**ceph-secret-admin.yaml**
apiVersion: v1
kind: Secret

data:

}
},
"spec": {

],
"resources": {
"requests": {

}
}
}
}
