Global Configuration

These configuration variables apply to all Trident configurations, regardless of the storage platform being used.

Option	Description	Example
version	Config file version number	1
storageDriverName	ontap-nas, ontap-san, ontap-nas-economy, ontap-nas-flexgroup, eseries-iscsi, solidfire-san, azure-netapp-files, aws-cvs, or gcp-cvs.	ontap-nas
storagePrefix	Optional prefix for volume names. Default: “netappdvp_”.	staging_
limitVolumeSize	Optional restriction on volume sizes. Default: “” (not enforced)	10g

Also, default option settings are available to avoid having to specify them on every volume create. The size option is available for all controller types. See the ONTAP config section for an example of how to set the default volume size.

Defaults Option	Description	Example
size	Optional default size for new volumes. Default: “1G”	10G

Storage Prefix

Do not use a storagePrefix (including the default) for Element backends. By default the solidfire-san driver will ignore this setting and not use a prefix. We recommend using either a specific tenantID for docker volume mapping or using the attribute data which is populated with the docker version, driver info and raw name from docker in cases where any name munging may have been used.

A note of caution: docker volume rm will delete these volumes just as it does volumes created by the plugin using the default prefix. Be very careful when using pre-existing volumes!
