capability Block

The capability block allows validating that a volume meets the requested capabilities.

id           = "ebs_prod_db1"namespace    = "default"name         = "database"type         = "csi"plugin_id    = "ebs-prod"capacity_max = "200G"capacity_min = "100G" capability {  access_mode     = "single-node-reader-only"  attachment_mode = "file-system"}

You must provide at least one capability block, and you must provide a block for each capability you intend to use in a job's volume block.

capability Parameters

• access_mode (string: <required>) - Defines whether a volume should be available concurrently. Can be one of "single-node-reader-only", "single-node-writer", "multi-node-reader-only", "multi-node-single-writer", or "multi-node-multi-writer". Most CSI plugins support only single-node modes. Consult the documentation of the storage provider and CSI plugin.

• attachment_mode (string: <required>) - The storage API that will be used by the volume. Most storage providers will support "file-system", to mount volumes using the CSI filesystem API. Some storage providers will support "block-device", which will mount the volume with the CSI block device API within the container.

capability Examples

The following examples only show the capability blocks. Remember that the capability block is only valid in the placement shown above.

Multiple capabilities

This examples shows a volume that must satisfy multiple capability requirements.

capability {  access_mode     = "single-node-reader-only"  attachment_mode = "file-system"} capability {  access_mode     = "single-node-writer"  attachment_mode = "file-system"}
