|
(an example is provided in the Appendix below).
|
||||||
|
|
||||||
|
"Derivative Works" shall mean any work, whether in Source or Object
|
||||||
|
form, that is based on (or derived from) the Work and for which the
|
||||||
|
editorial revisions, annotations, elaborations, or other modifications
|
||||||
|
represent, as a whole, an original work of authorship. For the purposes
|
||||||
|
of this License, Derivative Works shall not include works that remain
|
||||||
|
separable from, or merely link (or bind by name) to the interfaces of,
|
||||||
|
the Work and Derivative Works thereof.
|
||||||
|
|
||||||
|
"Contribution" shall mean any work of authorship, including
|

|
||||||
|
the copyright owner. For the purposes of this definition, "submitted"
|
||||||

|
||||||
|
excluding communication that is conspicuously marked or otherwise
|
||||||
|
designated in writing by the copyright owner as "Not a Contribution."
|
||||||
|
|
||||||
|
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||||
|
on behalf of whom a Contribution has been received by Licensor and
|
||||||
|
subsequently incorporated within the Work.
|

|
||||||
|
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
copyright license to reproduce, prepare Derivative Works of,
|
||||||
|
publicly display, publicly perform, sublicense, and distribute the
|
||||||
|
Work and such Derivative Works in Source or Object form.
|
||||||
|
|
||||||
|
3. Grant of Patent License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
(except as stated in this section) patent license to make, have made,
|
||||||
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||||
|
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
|
||||||
|
Work or Derivative Works thereof in any medium, with or without
|
||||||
|
modifications, and in Source or Object form, provided that You
|
||||||
|
meet the following conditions:
|
||||||
|
|
||||||
|
(a) You must give any other recipients of the Work or
|
||||||
|
Derivative Works a copy of this License; and
|
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices
|
||||||
|
stating that You changed the files; and
|
||||||
|
|
||||||
|
(c) You must retain, in the Source form of any Derivative Works
|
||||||
|
that You distribute, all copyright, patent, trademark, and
|
||||||
|
attribution notices from the Source form of the Work,
|
||||||
|
excluding those notices that do not pertain to any part of
|
||||||
|
the Derivative Works; and
|
||||||
|
|
||||||
|
(d) If the Work includes a "NOTICE" text file as part of its
|
||||||
|
distribution, then any Derivative Works that You distribute must
|
||||||
|
include a readable copy of the attribution notices contained
|
||||||
|
within such NOTICE file, excluding those notices that do not
|
||||||
|
pertain to any part of the Derivative Works, in at least one
|
||||||
|
of the following places: within a NOTICE text file distributed
|
||||||
|
as part of the Derivative Works; within the Source form or
|
||||||
|
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
|
||||||
|
the terms of any separate license agreement you may have executed
|
||||||
|
with Licensor regarding such Contributions.
|
||||||
|
|
||||||
|
6. Trademarks. This License does not grant permission to use the trade
|
||||||
|
names, trademarks, service marks, or product names of the Licensor,
|
||||||
|
except as required for reasonable and customary use in describing the
|
||||||
|
origin of the Work and reproducing the content of the NOTICE file.
|
||||||
|
|
||||||
|
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||||
|
agreed to in writing, Licensor provides the Work (and each
|
||||||
|
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||||
|
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||||
|
implied, including, without limitation, any warranties or conditions
|
||||||
|
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||||
|
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||||
|
appropriateness of using or redistributing the Work and assume any
|
||||||
|
risks associated with Your exercise of permissions under this License.
|
||||||
|
|
||||||
|
8. Limitation of Liability. In no event and under no legal theory,
|
||||||
|
whether in tort (including negligence), contract, or otherwise,
|
||||||
|
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.
|
||||||
|
|
||||||
|
END OF TERMS AND CONDITIONS

# CSI for s3
|
||||||
|
This is a Container Storage Interface ([CSI](https://github.com/container-storage-interface/spec/blob/master/spec.md)) for s3 (or s3 compatible) storage. This can dynamically allocate buckets and mount them via a fuse mount into any container.
|
||||||
|
|
||||||
|
# Kubernetes installation
|
||||||
|
## Requirements
|
||||||
|
* Kubernetes 1.10+
|
||||||
|
* Kubernetes has to allow privileged containers
|
||||||
|
* Docker daemon must allow shared mounts (systemd flag `MountFlags=shared`)
|
||||||
|
|
||||||
|
## 1. Create a secret with your S3 credentials
|
||||||
|
The endpoint is optional if you are using something else than AWS S3.
|
||||||
|
```yaml
|
||||||
|
apiVersion: v1
|
||||||
|
kind: Secret
|
||||||
|
metadata:
|
||||||
|
name: csi-s3-secret
|
||||||
|
namespace: kube-system
|
||||||
|
stringData:
|
||||||
|
accessKeyID: <YOUR_ACCESS_KEY_ID>
|
||||||
|
secretAccessKey: <YOUR_SECRET_ACCES_KEY>
|
||||||
|
endpoint: <S3_ENDPOINT_URL
|
||||||
|
region: <S3_REGION>
|
||||||
|
```
|
||||||
|
|
||||||
|
## 2. Deploy the driver
|
||||||
|
```bash
|
||||||
|
cd deploy/kubernetes
|
||||||
|
$ kubectl create -f provisioner.yaml
|
||||||
|
$ kubectl create -f attacher.yaml
|
||||||
|
$ kubectl create -f csi-s3-driver.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
## 3. Create the storage class
|
||||||
|
```bash
|
||||||
|
$ kubectl create -f storageclass.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
## 4. Test the S3 driver
|
||||||
|
* Create a pvc using the new storage class:
|
||||||
|
```bash
|
||||||
|
$ kubectl create -f pvc.yaml
|
||||||
|
```
|
||||||
|
* Check if the PVC has been bound:
|
||||||
|
```bash
|
||||||
|
$ kubectl get pvc csi-s3-pvc
|
||||||
|
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
|
||||||
|
csi-s3-pvc Bound pvc-c5d4634f-8507-11e8-9f33-0e243832354b 5Gi RWX csi-s3 9s
|
||||||
|
```
|
||||||
|
* Create a test pod which mounts your volume:
|
||||||
|
```bash
|
||||||
|
$ kubectl create -f poc.yaml
|
||||||
|
```
|
||||||
|
If the pod can start, everything should be working.
|
||||||
|
|
||||||
|
* Test the mount
|
||||||
|
```bash
|
||||||
|
$ kubectl exec -ti csi-s3-test-nginx bash
|
||||||
|
$ mount | grep fuse
|
||||||
|
s3fs on /var/lib/www/html type fuse.s3fs (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other)
|
||||||
|
$ touch /var/lib/www/html/hello_world
|
||||||
|
```
|
||||||
|
If something does not work as expected, check the troubleshooting section below.
|
||||||
|
|
||||||
|
# Additional configuration
|
||||||
|
## Mounter
|
||||||
|
By default the driver will use [s3fs](https://github.com/s3fs-fuse/s3fs-fuse) to mount buckets. Alternatively you can configure the storage class to use [goofys](https://github.com/kahing/goofys) for mounting s3 buckets. Note that goofys has some drawbacks in regards to POSIX compliance but in return offers better Performance than s3fs.
|
||||||
|
|
||||||
|
To configure a storage class to use goofys, just set the `mounter` parameter to `goofys`
|
||||||
|
```yaml
|
||||||
|
kind: StorageClass
|
||||||
|
apiVersion: storage.k8s.io/v1
|
||||||
|
metadata:
|
||||||
|
name: csi-s3
|
||||||
|
provisioner: ch.ctrox.csi.s3-driver
|
||||||
|
parameters:
|
||||||
|
mounter: goofys
|
||||||
|
csiProvisionerSecretName: csi-s3-secret
|
||||||
|
csiProvisionerSecretNamespace: kube-system
|
||||||
|
```
|
||||||
|
|
||||||
|
# Limitations
|
||||||
|
As S3 is not a real file system there are some limitations to consider here. Depending on what mounter you are using, you will have different levels of POSIX compability. Also depending on what S3 storage backend you are using there are not always consistency guarantees. The detailed limitations can be found on the documentation of [s3fs](https://github.com/s3fs-fuse/s3fs-fuse#limitations) and [goofys](https://github.com/kahing/goofys#current-status).
|
||||||
|
|
||||||
|
# Troubleshooting
|
||||||
|
## Issues while creating PVC
|
||||||
|
* Check the logs of the provisioner:
|
||||||
|
```
|
||||||
|
$ kubectl logs -l app=csi-provisioner-s3 -c s3-csi-driver
|
||||||
|
```
|
||||||
|
|
||||||
|
## Issues creating containers
|
||||||
|
* Ensure feature gate `MountPropagation` is not set to `false`
|
||||||
|
* Check the logs of the s3-driver:
|
||||||
|
```
|
||||||
|
$ kubectl logs -l app=csi-s3-driver -c csi-s3-driver
|
||||||
|
```
|
||||||
|
|
||||||
|
# Development
|
||||||
|
This project can be built like any other go application.
|
||||||
|
```bash
|
||||||
|
$ go get -u github.com/ctrox/csi-s3-driver
|
||||||
|
```
|
||||||
|
## Build
|
||||||
|
```bash
|
||||||
|
$ make build
|
||||||
|
```
|
||||||
|
## Tests
|
||||||
|
Currently the driver is tested by the [CSI Sanity Tester](https://github.com/kubernetes-csi/csi-test/tree/master/pkg/sanity). As end-to-end tests require S3 storage and a mounter like s3fs, this is best done in a docker container. A Dockerfile and the test script are in the `test` directory. The easiest way to run the tests is to just use the make command:
|
||||||
|
```bash
|
||||||
|
$ make test
|
||||||
|
```
