# Container Storage Interface (CSI) for SeaweedFs
|
|
[Container storage interface](https://kubernetes-csi.github.io/docs/) is an [industry standard](https://github.com/container-storage-interface/spec/blob/master/spec.md) that will enable storage vendors to develop a plugin once and have it work across a number of container orchestration systems.
|
|
|
|
[SeaweedFS](https://github.com/chrislusf/seaweedfs) is a simple and highly scalable distributed file system, to store and serve billions of files fast!
|
|
|
|
# Deployment (Kubernetes)
|
|
#### Prerequisites:
|
|
* Already have a working Kubernetes cluster (includes `kubectl`)
|
|
* Already have a working SeaweedFS cluster
|
|
|
|
## Utilize exiting SeaweedFS storage for your Kubernetes cluster (bare metal)
|
|
|
|
1. Git clone this repository and add your SeaweedFS master IP to `deploy/kubernetes/seaweedfs-csi.yaml` (2 places)
|
|
|
|
2. Apply the container storage interface for SeaweedFS for your cluster
|
|
```
|
|
$ kubectl apply -f deploy/kubernetes/seaweedfs-csi.yaml
|
|
```
|
|
3. Ensure all the containers are ready and running
|
|
```
|
|
$ kubectl get po -n kube-system
|
|
```
|
|
4. Testing: Create a persistant volume claim for 5GiB with name `seaweedfs-csi-pvc` with storage class `seaweedfs-storage`. The value, 5Gib does not have any significance as for SeaweedFS the whole filesystem is mounted into the container.
|
|
```
|
|
$ kubectl apply -f deploy/kubernetes/sample-seaweedfs-pvc.yaml
|
|
```
|
|
5. Verify if the persistant volume claim exists and wait until its the STATUS is `Bound`
|
|
```
|
|
$ kubectl get pvc
|
|
```
|
|
6. After its in `Bound` state, create a sample workload mounting that volume
|
|
```
|
|
$ kubectl apply -f deploy/kubernetes/sample-busybox-pod.yaml
|
|
```
|
|
7. Verify the storage mount of the busybox pod
|
|
```
|
|
$ kubectl exec my-csi-app -- df -h
|
|
```
|
|
8. Clean up
|
|
```
|
|
$ kubectl delete -f deploy/kubernetes/sample-busybox-pod.yaml
|
|
$ kubectl delete -f deploy/kubernetes/sample-seaweedfs-pvc.yaml
|
|
$ kubectl delete -f deploy/kubernetes/seaweedfs-csi.yaml
|
|
```
