iRODS Container Storage Interface (CSI) Driver implements the CSI Specification to provide container orchestration engines (like Kubernetes) iRODS access.
iRODS CSI Driver only supports CSI Specification Version v1.2.0 or higher.
iRODS CSI Driver relies on external iRODS clients for mounting iRODS collections.
| Driver Type | iRODS Client | Volume Provisioning | Server Requirements |
|---|---|---|---|
| irodsfuse | iRODS FUSE | Static, Dynamic | no |
| webdav | DavFS2 | Static | require iRODS-WebDAV or Davrods |
| nfs | NFS (nfs-common) | Static | require NFS-RODS |
Parameters specified in Persistent Volume (PV) and Storage Class (SC) are passed to iRODS CSI Driver to mount a volume. Depending on driver types, different parameters should be given.
For static volume provisioning, parameters are given via Persistent Volume (PV). For dynamic volume provisioning, parameters are given via Storage Class (SC).
| Field | Description | Example |
|---|---|---|
| client | Driver type | "irodsfuse" |
| user | iRODS user id | "irods_user" |
| password | iRODS user password | "password" in plane text |
| clientuser | iRODS client user id (when using proxy auth) | "irods_cilent_user" |
| host | iRODS hostname | "data.cyverse.org" |
| port | iRODS port | Optional, Default "1247" |
| zone | iRODS zone | "iplant" |
| path | iRODS path to mount, starts with zone in string | "/iplant/home/irods_user" |
| monitorURL | URL to irodsfs monitor service | "http://monitor.abc.com" |
| pathMappingJSON | JSON string for custom path mappings | "{}" |
| volumeRootPath | iRODS path to mount. Creates a subdirectory per persistent volume. (only for dynamic volume provisioning) | "/iplant/home/irods_user" |
| retainData | "true" to not clear the volume after use. (only for dynamic volume provisioning) | "false". "false" by default. |
| noVolumeDir | "true" to not create a subdirectory under volumeRootPath. It mounts the volumeRootPath. (only for dynamic volume provisioning) |
"false". "false" by default. |
| enforceProxyAccess | "true" to mandate passing clientUser, or giving different user as in global configuration. |
"false". "false" by default. |
| mountPathWhitelist | a comma-separated list of paths to allow mount. | "/iplant/home" |
Mounts path
user and password can be supplied via secrets (nodeStageSecretRef).
