## Overview
Ceph CSI plugins implement an interface between CSI enabled Container Orchestrator (CO) and CEPH cluster. It allows dynamically provisioning CEPH volumes and attaching them to workloads. Current implementation of Ceph CSI plugins was tested in Kubernetes environment (requires Kubernetes 1.11+), but the code does not rely on any Kubernetes specific calls (WIP to make it k8s agnostic) and should be able to run with any CSI enabled CO.

# ceph-csi-cephfs
The ceph-csi-cephfs chart adds cephfs volume support to your cluster.
## Install Chart
To install the Chart into your Kubernetes cluster
```bash
helm install --namespace "ceph-csi-cephfs" --name "ceph-csi-cephfs" ceph-csi/ceph-csi-cephfs
```
After installation succeeds, you can get a status of Chart
```bash
helm status "ceph-csi-cephfs"
```
If you want to delete your Chart, use this command
```bash
helm delete --purge "ceph-csi-cephfs"
```
If you want to delete the namespace, use this command
```bash

Volumes that were provisioned dynamically (i.e. `provisionVolume=true`) are allowed to be deleted by the driver as well, if the user chooses to do so. Otherwise, the driver is forbidden to delete such volumes - attempting to delete them is a no-op.

Admin credentials are required for provisioning new RBD images
`ADMIN_NAME`: `ADMIN_PASSWORD` - note that the key of the key-value pair is the name of the client with admin privileges, and the value is its password
NOTE: If `clusterID` parameter is used, then an accompanying Ceph cluster
configuration secret or config files needs to be provided to the running pods.
Refer to [Cluster ID based configuration](../examples/README.md#cluster-id-based-configuration)
for more information. A suggested way to populate the clusterID is to use the
output of `ceph fsid` of the Ceph cluster to be used for provisioning.
**Required secrets:**
Admin credentials are required for provisioning new RBD images `ADMIN_NAME`:
`ADMIN_PASSWORD` - note that the key of the key-value pair is the name of the
client with admin privileges, and the value is its password
If clusterID is specified, then a secret with various keys and values as

## Deployment with Kubernetes
Requires Kubernetes 1.11
Your Kubernetes cluster must allow privileged pods (i.e. `--allow-privileged` flag must be set to true for both the API server and the kubelet). Moreover, as stated in the [mount propagation docs](https://kubernetes.io/docs/concepts/storage/volumes/#mount-propagation), the Docker daemon of the cluster nodes must allow shared mounts.

Both `rbd` and `cephfs` directories contain `plugin-deploy.sh` and `plugin-teardown.sh` helper scripts. You can use those to help you deploy/tear down RBACs, sidecar containers and the plugin in one go. By default, they look for the YAML manifests in `../../deploy/{rbd,cephfs}/kubernetes`. You can override this path by running `$ ./plugin-deploy.sh /path/to/my/manifests`.

## How to test RBD Snapshot feature
Before continuing, make sure you enabled the required [feature gate](https://kubernetes-csi.github.io/docs/snapshot-restore-feature.html#snapshot-apis) in your Kubernetes cluster.
Before continuing, make sure you enabled the required
feature gate `VolumeSnapshotDataSource=true` in your Kubernetes cluster.
In the `examples/rbd` directory you will find four files related to snapshots: [csi-snapshotter-rbac.yaml](./rbd/csi-snapshotter-rbac.yaml), [csi-snapshotter.yaml](./rbd/csi-snapshotter.yaml), [snapshotclass.yaml](./rbd/snapshotclass.yaml) and [snapshot.yaml](./rbd/snapshot.yaml).
In the `examples/rbd` directory you will find two files related to snapshots:
[snapshotclass.yaml](./rbd/snapshotclass.yaml) and
[snapshot.yaml](./rbd/snapshot.yaml).
Once you created your RBD volume, you'll need to customize at least `snapshotclass.yaml` and make sure the `monitors` and `pool` parameters match your Ceph cluster setup. If you followed the documentation to create the rbdplugin, you shouldn't have to edit any other file. If you didn't, make sure every parameters in `csi-snapshotter.yaml` reflect your configuration.

After configuring everything you needed, deploy the snapshot class:
```bash
kubectl create -f csi-snapshotter-rbac.yaml
kubectl create -f csi-snapshotter.yaml
kubectl create -f snapshotclass.yaml
```
Verify that the snapshot class was created:
```console
$ kubectl get volumesnapshotclass
NAME AGE
csi-rbdplugin-snapclass 4s
```
Create a snapshot from the existing PVC:
```bash
kubectl create -f snapshot.yaml
```
To verify if your volume snapshot has successfully been created, run the following:
```bash
$ kubectl get volumesnapshotclass
NAME AGE
csi-rbdplugin-snapclass 4s
```console
$ kubectl get volumesnapshot
NAME AGE
rbd-pvc-snapshot 6s
```
To be sure everything is OK you can run `rbd snap ls [your-pvc-name]` inside one of your Ceph pod.
## How to test RBD Block Volume
Before continuing, make sure you enabled the required [feature gate](https://kubernetes-csi.github.io/docs/raw-block.html#usage) in your Kubernetes cluster.
In order to create a PVC in Block mode, you need to specify `volumeMode: Block` in the PVC spec.
In the `examples/rbd` directory, you can test RBD block volume by running:
To check the status of the snapshot, run the following:
```bash
kubectl create -f pvc-block.yaml
kubectl create -f pod-block.yaml
$ kubectl describe volumesnapshot rbd-pvc-snapshot

```
To be sure everything is OK you can run `rbd snap ls [your-pvc-name]` inside
one of your Ceph pod.
To restore the snapshot to a new PVC, deploy
[pvc-restore.yaml](./rbd/pvc-restore.yaml) and a testing pod
[pod-restore.yaml](./rbd/pod-restore.yaml):
```bash
kubectl create -f pvc-restore.yaml
kubectl create -f pod-restore.yaml
```
## How to test RBD MULTI_NODE_MULTI_WRITER BLOCK feature
Requires feature-gates: `BlockVolume=true` `CSIBlockVolume=true`
*NOTE* The MULTI_NODE_MULTI_WRITER capability is only available for
Volumes that are of access_type `block`
*WARNING* This feature is strictly for workloads that know how to deal
with concurrent access to the Volume (eg Active/Passive applications).
Using RWX modes on non clustered file systems with applications trying
to simultaneously access the Volume will likely result in data corruption!
Following are examples for issuing a request for a `Block`
`ReadWriteMany` Claim, and using the resultant Claim for a POD
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: block-pvc
spec:
accessModes:
- ReadWriteMany
volumeMode: Block
resources:
requests:
storage: 1Gi
storageClassName: csi-rbd
```
Create a POD that uses this PVC:
```yaml
apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
containers:
- name: my-container
image: debian
command: ["/bin/bash", "-c"]
args: [ "tail -f /dev/null" ]
volumeDevices:
- devicePath: /dev/rbdblock
name: my-volume
imagePullPolicy: IfNotPresent
volumes:
- name: my-volume
persistentVolumeClaim:
claimName: block-pvc
```
Now, we can create a second POD (ensure the POD is scheduled on a different
node; multiwriter single node works without this feature) that also uses this
PVC at the same time, again wait for the pod to enter running state, and verify
the block device is available.
```yaml
apiVersion: v1
kind: Pod
metadata:
name: another-pod
spec:
containers:
- name: my-container
image: debian
command: ["/bin/bash", "-c"]
args: [ "tail -f /dev/null" ]
volumeDevices:
- devicePath: /dev/rbdblock
name: my-volume
imagePullPolicy: IfNotPresent
volumes:
- name: my-volume
persistentVolumeClaim:
claimName: block-pvc
```
Wait for the PODs to enter Running state, check that our block device
is available in the container at `/dev/rdbblock` in both containers:
```bash
$ kubectl exec -it my-pod -- fdisk -l /dev/rbdblock
Disk /dev/rbdblock: 1 GiB, 1073741824 bytes, 2097152 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 4194304 bytes / 4194304 bytes
```
```bash
$ kubectl exec -it another-pod -- fdisk -l /dev/rbdblock
Disk /dev/rbdblock: 1 GiB, 1073741824 bytes, 2097152 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 4194304 bytes / 4194304 bytes
```
## Cluster ID based configuration
Before creating a storage class that uses the option `clusterID` to refer to a
Ceph cluster, the following actions need to be completed.
Get the following information from the Ceph cluster,
* Admin ID and key, that has privileges to perform CRUD operations on the Ceph
cluster and pools of choice
* Key is typically the output of, `ceph auth get-key client.admin` where
`admin` is the Admin ID
* Used to substitute admin/user id and key values in the files below
* Ceph monitor list
* Typically in the output of `ceph mon dump`
* Used to prepare comma separated MON list where required in the files below
* Ceph Cluster fsid
* If choosing to use the Ceph cluster fsid as the unique value of clusterID,
* Output of `ceph fsid`
* Used to substitute `<cluster-id>` references in the files below
Update the template
[template-ceph-cluster-ID-secret.yaml](./rbd/template-ceph-cluster-ID-secret.yaml)
with values from
a Ceph cluster and replace `<cluster-id>` with the chosen clusterID to create
the following secret,
* `kubectl create -f rbd/template-ceph-cluster-ID-secret.yaml`
Storage class and snapshot class, using `<cluster-id>` as the value for the
option `clusterID`, can now be created on the cluster.
Remaining steps to test functionality remains the same as mentioned in the
sections above.
