The Archil CSI Driver is currently in preview.
The Archil CSI Driver provides seamless integration between Kubernetes and Archil’s distributed disk technology. It implements the CSI specification to allow Kubernetes workloads to mount and use Archil volumes with both ReadWriteOnce (RWO) and ReadWriteMany (RWX) access modes. Requirements:
  • Helm chart distribution: The driver is provided as an OCI Helm chart and requires Helm v3.8.0 or newer.
  • DNS access: Pods must have access to external DNS to mount Archil disks. (Note: some providers, such as Fly.io, don’t enable this by default.)

​
Quickstart

The Archil CSI Driver does not support dynamic provisioning of disks. You must create the disk in the Archil console first.

​
1. Install CSI driver

Install the CSI driver using our official Helm chart from Docker Hub. The chart deploys the archildata/csi-driver container image. 
helm install archil-csi-driver \
  oci://registry-1.docker.io/archildata/csi-driver-chart \
  --namespace archil-system \
  --create-namespace

​
2. Configure disk users

  • AWS: IAM Role Authorization
  • Token Authorization
Archil natively supports using AWS IAM users or roles to authorize access to the disk. Simply add the ARN of the IAM user or role that will be used to connect to the disk.
  • Get your EC2 server’s IAM role arn using the following command:
aws sts get-caller-identity --query 'Arn' --output text |\
sed 's/\:sts\:/\:iam\:/' |\
sed 's/\:assumed-role\//\:role\//' |\
cut -d'/' -f1-2
  • Copy the resulting IAM role arn.
  • Update your helm release:
helm upgrade archil-csi-driver \
  oci://registry-1.docker.io/archildata/csi-driver-chart \
  --set serviceAccount.annotations."eks\.amazonaws\.com/role-arn"=arn:aws:iam::123456789012:role/ArchilCSIRole
  • Restart the CSI driver daemonset:
kubectl rollout restart daemonset/archil-csi-node -n archil-system
This IAM role is used for authentication from the CSI driver to all disks. The Archil CSI Driver does not currently support specifying IAM roles on a per-disk basis.

​
3. Create PersistentVolume

apiVersion: v1
kind: PersistentVolume
metadata:
  name: archil-pv
spec:
  capacity:
    # Can be any size, Archil disks are infinite
    storage: 1000Gi
  accessModes:
    # Or use ReadWriteOnce for single-node access
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  csi:
    driver: csi.archil.com
    # Your disk ID from Archil console
    volumeHandle: dsk-XXXXXXXXXXXX
    volumeAttributes:
      # Region where your disk exists
      region: aws-us-east-1
  # Only include this section if using token authentication:
  # nodePublishSecretRef:
  #   name: archil-token-dsk-XXXXXXXXXXXX
  #   namespace: archil-system

​
4. Create PersistentVolumeClaim

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: archil-pvc
  namespace: default
spec:
  # Must match PV access mode
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1000Gi
  # Must match PV name
  volumeName: archil-pv

​
5. Create a pod

This example creates a simple demo pod to verify connectivity to your Archil disk. You can deploy your own applications using any pod configuration, just mount the PVC as shown below. 
apiVersion: v1
kind: Pod
metadata:
  name: archil-test
spec:
  containers:
  - name: test
    image: busybox
    command: ['sh', '-c', 'ls -la /data && echo "---" && echo "Archil disk contents listed above"']
    volumeMounts:
    - name: archil-storage
      mountPath: /data
  volumes:
  - name: archil-storage
    persistentVolumeClaim:
      # Must match PVC name
      claimName: archil-pvc
  restartPolicy: Never

​
Configuration reference

​
Storage access modes

The accessMode that you use when creating your PersistentVolume and PersistentVolumeClaim will determine whether the disk is mounted with support for other clients to access it. When using ReadWriteOnce, the disk is mounted into single ownership mode, preventing other clients from accessing the disk. When using ReadWriteMany, the disk is mounted with --shared, allowing multiple clients to access the disk simultaneously. For more details, see the Shared Disks page.
