+# CephFS Volume Provisioner for Kubernetes 1.5+
+
+[![Docker Repository on Quay](https://quay.io/repository/external_storage/cephfs-provisioner/status "Docker Repository on Quay")](https://quay.io/repository/external_storage/cephfs-provisioner)
+
+Using Ceph volume client
+
+## Development
+
+Compile the provisioner
+
+``` console
+make
+```
+
+Make the container image and push to the registry
+
+``` console
+make push
+```
+
+## Test instruction
+
+- Start Kubernetes local cluster
+
+See [Kubernetes](https://kubernetes.io/)
+
+- Create a Ceph admin secret
+
+``` bash
+ceph auth get client.admin 2>&1 |grep "key = " |awk '{print  $3'} |xargs echo -n > /tmp/secret
+kubectl create ns cephfs
+kubectl create secret generic ceph-secret-admin --from-file=/tmp/secret --namespace=cephfs
+```
+
+- Start CephFS provisioner
+
+The following example uses `cephfs-provisioner-1` as the identity for the instance and assumes kubeconfig is at `/root/.kube`. The identity should remain the same if the provisioner restarts. If there are multiple provisioners, each should have a different identity.
+
+``` bash
+docker run -ti -v /root/.kube:/kube -v /var/run/kubernetes:/var/run/kubernetes --privileged --net=host cephfs-provisioner /usr/local/bin/cephfs-provisioner -master=http://127.0.0.1:8080 -kubeconfig=/kube/config -id=cephfs-provisioner-1
+```
+
+Alternatively, deploy it in kubernetes, see [deployment](deploy/README.md).
+
+- Create a CephFS Storage Class
+
+Replace Ceph monitor's IP in [example class](example/class.yaml) with your own and create storage class:
+
+``` bash
+kubectl create -f example/class.yaml
+```
+
+- Create a claim
+
+``` bash
+kubectl create -f example/claim.yaml
+```
+
+- Create a Pod using the claim
+
+``` bash
+kubectl create -f example/test-pod.yaml
+```
+
+## Known limitations
+
+- Kernel CephFS doesn't work with SELinux, setting SELinux label in Pod's securityContext will not work.
+- Kernel CephFS doesn't support quota or capacity, capacity requested by PVC is not enforced or validated.
+- Currently each Ceph user created by the provisioner has `allow r` MDS cap to permit CephFS mount.
