»Volumes HTTP API

The /volume and /volumes endpoints are used to query for and interact with volumes.

»List Volumes

This endpoint lists all volumes.

MethodPathProduces
GET/v1/volumesapplication/json

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking QueriesACL Required
YESnamespace:csi-list-volume

»Parameters

  • type (string: "") - Specifies the type of volume to query. Currently only supports csi. This is specified as a query string parameter. Returns an empty list if omitted.

  • node_id (string: "") - Specifies a string to filter volumes based on an Node ID prefix. Because the value is decoded to bytes, the prefix must have an even number of hexadecimal characters (0-9a-f). This is specified as a query string parameter.

  • plugin_id (string: "") - Specifies a string to filter volumes based on a plugin ID prefix. Because the value is decoded to bytes, the prefix must have an even number of hexadecimal characters (0-9a-f). This is specified as a query string parameter.

NOnamespace:csi-write-volume

»Parameters

  • :volume_id (string: <required>) - Specifies the ID of the volume. This must be the full ID. This is specified as part of the path.

  • force (bool: false) - Force deregistration of the volume and immediately drop claims for terminal allocations. Returns an error if the volume has running allocations. This does not detach the volume from client nodes. This is specified as a query string parameter.

»Sample Request

$ curl \
    --request DELETE \
    https://localhost:4646/v1/volume/csi/volume-id1?force=false

$ curl \    --request DELETE \    https://localhost:4646/v1/volume/csi/volume-id1?force=false

»Delete Volume

This endpoint deletes an external volume from the storage provider, and deregisters it from Nomad. It is an error to delete a volume that is in use. Only CSI plugins that implement the Controller interface with the CREATE_DELETE_VOLUME capability support this endpoint.

»List External Volumes

This endpoint lists storage volumes that are known to the external storage provider but may not be registered with Nomad. Only CSI plugins that implement the Controller interface with the LIST_VOLUMES capability support this endpoint.

MethodPathProduces
GET/v1/volumes/externalapplication/json

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking QueriesACL Required
YESnamespace:csi-write-volume

»Parameters

  • plugin_id (string: "") - Specifies a string to filter volumes based on a plugin ID prefix. Because the value is decoded to bytes, the prefix must have an even number of hexadecimal characters (0-9a-f). This is specified as a query string parameter.

  • next_token (string: "") - This endpoint supports paging. The next_token parameter accepts a string returned in a previous response's NextToken field to request the next page of results.

  • per_page (int: <required>) - Specifies a maximum number of snapshots to return for this request. The response will include a NextToken field that can be passed to the next request to fetch additional pages.
