(except as stated in this section) patent license to make, have made,

where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.

4. Redistribution. You may reproduce and distribute copies of the

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Kubernetes XenServer Storage

***NOT PRODUCTION READY!!!*** *... yet*

**WARNING:**
XenServer credentials will be passed on every node and persisted to disk for every volume.
At the moment this is the only way to provide XenServer storage support to Kubernetes.
The next release which will be build against 1.10 should however address this.

## Getting Started

Install the *provisioner* and *driver*.
Detailed informations can be found in their respecive directories.

# Driver

Mounts and unmounts the volumes on the hosts itself.

## Installing

The volume driver needs to be installed on all nodes.

### Kubernetes

Kubernetes can install the driver through a *DaemonSet*, which can be created
by running this command:

```console
$ kubectl apply -f deploy/daemon.yaml
```

### OpenShift

OpenShift doesn't allow installing the driver trough a *DaemonSet*, execute the
the following commands on each node:

```console
mkdir -p /usr/libexec/kubernetes/kubelet-plugins/volume/exec/spangenberg.io~xenserver && \
wget https://github.com/stedolan/jq/releases/download/jq-1.5/jq-linux64 -O /usr/libexec/kubernetes/kubelet-plugins/volume/exec/spangenberg.io~xenserver/jq && \
