CSI-S3

Learn how to configure CSI-S3 for use with Filebase.

What is CSI-S3?
CSI-S3 is a container storage interface developed for S3-compatible storage. Container storage interfaces like CSI-S3 can dynamically allocate buckets and mount them via FUSE inside any container, such as Docker containers.
Read below to learn how to use CSI-S3 with Filebase.
Prerequisites:
Have a running Kubernetes cluster.​
Have Kubernetes tools such as kubectl and helm installed for use with your cluster.
​Download and install Docker on your Kubernetes cluster.
Confirm that Docker allows shared mounts, and Kubernetes allows privileged containers.
​Sign up for a free Filebase account. 
Have your Filebase Access and Secret Keys. Learn how to view your access keys here.
Create a Filebase Bucket. Learn how to create a bucket here.
1. Download the CSI-S3 GitHub repository into your working directory:
git clone https://github.com/CTrox/csi-s3
2. Create a new Kubernetes secret with the command:
kubectl create secret filebase-config
By default, this will create a file located at secret/filebase-config
3. Open this file and enter the following content:
apiVersion: v1
kind: Secret
metadata:
  namespace: kube-namespace
  name: csi-s3-secret
  namespace: kube-namespace
stringData:
  accessKeyID: FILEBASE_ACCESS_KEY
  secretAccessKey: FILEBASE_SECRET_KEY
  endpoint: https://s3.filebase.com
Replace the following values:
FILEBASE_ACCESS_KEY: Filebase Access Key
FILEBASE_SECRET_KEY: Filebase Secret Key
4. Next, deploy the driver for CSI-S3:
cd deploy/kubernetes
kubectl create -f provisioner.yaml
kubectl create -f attacher.yaml
kubectl create -f csi-s3.yaml
5. Then create a storage class using the command:
kubectl create -f examples/storageclass.yaml
6. Test the S3 driver with the following workflow:
kubectl create -f examples/pvc.yaml
Make sure that the PVC has been bound:
kubectl get pvc csi-s3-pvc
NAME         STATUS    VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
csi-s3-pvc   Bound     pvc-c5d24383235-4634f8507-11e8-9f330e4b   5Gi        RWO            csi-s3         12m
Then create and start a test pod:
kubectl create -f examples/pod.yaml
CSI-S3 will create a new bucket for each volume you create by default. The bucket will match the Volume’s ID.
To set configure a custom bucket name, edit the examples/storageclass.yaml file to reflect the following content:
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: csi-s3-existing-bucket
provisioner: ch.ctrox.csi.s3-driver
parameters:
  mounter: rclone
  bucket: filebase-bucket name
Note: This requires rClone to be installed to mount the bucket locally. For more information on rClone, check out our documentation here.
