SODA Integration with Vendor CSI Drivers via SODA CSI Plug-N-Play

SODA CSI Plug-N-Play is a mechanism by which users can use the heterogeneous storage vendors in a unified way, Users need to define the requirements while creating SODA Profile, Users need to use this profile ID while creating the PVC’s in the Kubernetes, the soda-csi-provisioner will automatically select the vendor csi-driver and help in provisioning the Volumes for Pods.


  • An installation of Kubernetes (V1.17+)
  • SODA installation (you can refer to quick start guide over here), you need to change the ports of etcd in osdb.yaml while installing SODA on an existing K8s environment as the ports cause conflict with k8s etcd.

Selecting the vendor CSI driver

You can select the CSI driver supported by SODA Plug-N-Play from here Once selected follow the instruction given in the document to deploy the CSI driver in K8s.

For this example we are selecting the OpenEBS LVM CSI Driver.
kubectl create -f

We need to do the additional step to make the lvm group for this plugin

truncate -s 1024G /tmp/disk.img
sudo losetup -f /tmp/disk.img --show

Create the Volume group on all the nodes, which will be used by the LVM Driver for provisioning the volumes

sudo pvcreate /dev/loop0
sudo vgcreate lvmvg /dev/loop0

Creating Profile in SODA

We need to create a Profile in SODA which will have the information of csi driver which needs to be used(eventually this step will be automatically done by SODA).

osdsctl profile create '{"name": "openebs-profile-soda","storageType": "block","description": "string","provisioningProperties": {"dataStorage": {"recoveryTimeObjective": 10,"provisioningPolicy": "Thick","compression": false,"deduplication": false,"characterCodeSet": "ASCII","maxFileNameLengthBytes": 255,"storageAccessCapability": ["Read"] },"ioConnectivity": {"accessProtocol": "iscsi","maxIOPS": 150,"minIOPS": 50,"maxBWS": 5,"minBWS": 1,"latency": 1}},"replicationProperties": {},"snapshotProperties": {},"dataProtectionProperties": { },"customProperties": {"driver": ""}}'

Attach information of ProfileID in Storage Class

Once the Profile ID is created then we need to create a Storage Class in K8s.

kind: StorageClass
  name: openebs-lvmsc-soda
allowVolumeExpansion: true
  volgroup: "lvmvg"
  profile: a82980d3-1030-41e5-95f0-b2db5a0c065d     ## SODA PROFILE ID
provisioner: soda-csi
- matchLabelExpressions:
  - key:
      - node-12340                                  ## NODE NAME ON WHICH PROVISIONING NEEDS TO BE DONE

Deploy an App with pvc

kubectl create -f
