CSI WekaFS Driver
This repository hosts the CSI WekaFS driver and all of its build and dependent configuration files to deploy the driver.
Pre-requisite
- Kubernetes cluster of version 1.18 and up, 1.19 and up recommended
- Helm v3 must be installed and configured properly
- Weka system pre-configured and Weka client installed and registered in cluster for each Kubernetes node
Deployment
helm repo add csi-wekafs https://weka.github.io/csi-wekafs
helm install csi-wekafsplugin csi-wekafs/csi-wekafsplugin --namespace csi-wekafsplugin --create-namespace [--set selinuxSupport=<off | mixed | enforced>]
NOTE: Since version 0.8.0, Weka CSI plugin supports installation on SELinux-enabled Kubernetes clusters Refer to SELinux Support & Installation Notes for additional information
NOTE: Since version 0.7.0, Weka CSI plugin transitions to API-based deployment model which requires API connectivity and credentials parameters to be set in Storage Class.
Kubernetes does not allow storage class modification for existing volumes, hence the recommended upgrade process is re-deploying new persistent volumes based on new storage class format.
However, for sake of more convenient migration, a
legacySecretNameparameter can be set that will bind existing legacy volumes to a Weka cluster API and allow volume expansion.For further information, refer Official Weka CSI Plugin documentation

Tolerations for all CSI driver components |
| controllerPluginTolerations | list | [{"effect":"NoSchedule","key":"node-role.kubernetes.io/master","operator":"Exists"}] |
Tolerations for CSI controller component only (by default same as global) |
| nodePluginTolerations | list | [{"effect":"NoSchedule","key":"node-role.kubernetes.io/master","operator":"Exists"}] |

| priorityClassName | string | "" |
Optional CSI Plugin priorityClassName |
| selinuxSupport | string | "off" |
Support SELinux labeling for Persistent Volumes, may be either off, mixed, enforced (default off) In enforced mode, CSI node components will only start on nodes having a label selinuxNodeLabel below In mixed mode, separate CSI node components will be installed on SELinux-enabled and regular hosts In off mode, only non-SELinux-enabled node components will be run on hosts without label. WARNING: if SELinux is not enabled, volume provisioning and publishing might fail! |
| selinuxNodeLabel | string | "csi.weka.io/selinux_enabled" |
This label must be set to "true" on SELinux-enabled Kubernetes nodes, e.g., to run the node server in secure mode on SELinux-enabled node, the node must have label csi.weka.io/selinux_enabled="true" |
| kubeletPath | string | "/var/lib/kubelet" |
kubelet path, in cases Kubernetes is installed not in default folder |
