Storage class configurations

The Weka CSI Plugin supports the following persistent volume types:

Dynamic: Persistent Volume Claim (PVC).
Static: Persistent Volume (PV).

The Weka CSI Plugin communicates with the WEKA cluster using REST API, leveraging this integration to provide extended capabilities, such as strictly enforcing volume capacity usage through integration with filesystem directory quota functionality. For details, see Quota management.

Starting from CSI Plugin v2.0, three StorageClass configurations are available:

Directory-backed StorageClass
Snapshot-backed StorageClass
Filesystem-backed StorageClass

API-based communication model

In the API-based model, the API endpoint addresses and authentication credentials must be provided to the WEKA CSI Plugin to establish a REST API connection with the WEKA cluster and perform configuration tasks.

The information is stored securely in Kubernetes secret, referred to by the Storage Class.

Adhere to the following:

The configuration described in this section applies to WEKA CSI Plugin version 0.8.4 and higher. To get all features, WEKA CSI Plugin version 2.0 is required.
Directory quota integration requires WEKA cluster version 3.13.0 and higher.
Snapshot quota integration requires WEKA cluster version 4.2 and higher.
Authenticated mounts for filesystems set with auth-required=true, and filesystems in the non-root organization, require WEKA cluster version 3.14.0 and higher.

The legacy communication model is deprecated and will be removed in the next release. If you are using the legacy communication model, replacing it with the API-based one is recommended.

Prerequisites

To provision any persistent volume type, a Storage Class must exist in Kubernetes deployment that matches the secret name and namespace in the WEKA cluster configuration.
For directory-backed and snapshot-backed storage class configurations, a filesystem must be pre-created on the WEKA cluster to create PVCs.
For the filesystem-backed StorageClass configuration, the filesystem name is generated automatically based on the PVC name, but the filesystem group name must be declared in the Storage Class configuration.

Configure secret data

Create a secret data file (see the following example).

Example: csi-wekafs-api-secret.yaml file

csi-wekafs/examples/dynamic_api/csi-wekafs-api-secret.yaml

apiVersion: v1
kind: Secret
metadata:
  name: csi-wekafs-api-secret
  namespace: csi-wekafs

  username: YWRtaW4=
  # A password to connect to the cluster API (base64-encoded)
  password: YWRtaW4=
  # An organization to connect to (default Root, base64-encoded)
  organization: Um9vdA==
  # A comma-separated list of cluster management endpoints. Format: <IP:port> (base64-encoded)
  # It is recommended to configure at least 2 management endpoints (cluster backend nodes), or a load-balancer if used

  # for multiple clusters setup, set a specific container name (base64-encoded)
  localContainerName: ""
  # for cloud deployments with automatic healing and auto-scaling, set to "true" to enable automatic updates of the endpoints.
  # The API endpoints will be updated automatically on first connection to the cluster API, as well as on each re-login
  # maybe either (true/false), base64-encoded
  # NOTE: if a load balancer is used to access the cluster API, leave this setting as "false"
  autoUpdateEndpoints: ZmFsc2U=
  # It is recommended to configure all NFS server IP addresses to better share the load/balance the traffic.
  # NOTE: this setting is optional and should be used only when the NFS Group IP addresses are not set in the cluster
  # WARNING: providing a load balancer IP address that uses NFS connection redirects (also known as `referrals`) to other servers is not supported.
  # e.g. 10.100.100.1,10.100.100.2
  nfsTargetIps: ""
  # When using HTTPS connection and self-signed or untrusted certificates, provide a CA certificate in PEM format, base64-encoded
  # for cloud deployments or other scenarios where setting an NFS Group IP addresses is not possible,
  # provide a comma-separated list of NFS target IP addresses in form of <IP> (base64-encoded)
  # caCertificate: <base64-encoded-PEM>
  caCertificate: ""

Apply the secret data and validate it is created successfully.

Apply the yaml file

# apply the secret .yaml file
$ kubectl apply -f csi-wekafs-api-secret.yaml

# Check the secret was successfully created
$ kubectl get secret csi-wekafs-api-secret -n csi-wekafs
NAME                    TYPE     DATA   AGE
csi-wekafs-api-secret   Opaque   5      7m

To provision CSI volumes on filesystems residing in non-root organizations or filesystems, set with auth-required=true. A CSI Plugin of version 0.8.4 and higher and WEKA cluster version 3.14 and higher are required.

Secret data parameters

All values in the secret data file must be in base64-encoded format.

Key Description Comments

Key	Description	Comments
`username`	The user name for API access to the WEKA cluster.	To run the CSI Plugin in a non-default organization, OrgAdmin permission is required. In other cases, ClusterAdmin permission is required. It is recommended that you create a separate user for the CSI Plugin. See User management.
`password`	The user password for API access to the WEKA cluster.
`organization`	The WEKA organization name for the user. For a single organization, use `Root`.	You can use multiple secrets to access multiple organizations, which are specified in different storage classes.
`scheme`	The URL scheme that is used for communicating with the WEKA cluster API.	`http` or `https` can be used. The user must ensure that the Weka cluster was configured to use the same connection scheme.
`endpoints`	Comma-separated list of endpoints consisting of IP address and port. For example, `172.31.15.113:14000,172.31.12.91:14000`	For redundancy, specify the management IP addresses of at least 2 backend servers.
`localContainerName`	WEKA client container name for the client connected to the relevant WEKA cluster. Only required when connecting a K8s worker node to multiple WEKA clusters. For a single cluster, do not set this parameter.	All local container names relevant to a specific WEKA cluster must be the same across all k8s worker nodes. For details, see Connect k8s worker nodes to multiple WEKA clusters
`autoUpdateEndpoints`	Specify whether the WEKA CSI Plugin performs automatic periodic updates of API endpoints (`true` or `false`).	In cloud-based clusters with automatic scaling and healing, the IP addresses of management containers can change over time. To prevent losing API connectivity, the plugin can automatically retrieve all management container IP addresses from the cluster at login. If using an external load balancer, set this option to `false`.
`nfsTargetIps`	A comma-separated list of IP addresses to use when publishing volumes over NFS.	Normally, the system automatically retrieves IP addresses from the interface group defined on the WEKA cluster, leaving this parameter empty. However, if no Virtual IP addresses are set on the interface group (for example, in cloud environments), manually provide the IP addresses in this parameter.
`caCertificate`	custom CA certificate used to generate the HTTPS certificate for the WEKA cluster. The certificate must be in PEM format and Base64-encoded.	As of WEKA version 4.3.0, HTTPS communication is mandatory. To ensure a secure connection without bypassing certificate checks, it's recommended to provide the certificate file within a secret.

Connect K8s worker nodes to multiple WEKA clusters

A single K8s worker node can be connected to multiple WEKA clusters (maximum 7 clusters) simultaneously.

Procedure

For each k8s worker node, create a number of WEKA client containers according to the number of clusters you want to connect to. The WEKA client container name must be according to the WEKA cluster that is connected to. For example, to connect to 7 WEKA clusters, it is required to create 7 WEKA client containers named client 1, client 2, and so on.
Create secret data files for each WEKA cluster. In the localContainerName set the relevant client container name. For example, for client 1 set the name of the client container connected to cluster 1.
Configure storage classes using the relevant secret data file.

Filesystem names used for k8s (defined in the storage classes) must be unique across all clusters.

Configure directory-backed StorageClass

Create a directory-backed storage class yaml file (see the following example).
