openstack_blockstorage_volume_attach_v2

Attaches a Block Storage Volume to an Instance using the OpenStack Block Storage (Cinder) v2 API.

Example Usage

resource "openstack_blockstorage_volume_v2" "volume_1" {
  name = "volume_1"
  size = 1
}

resource "openstack_compute_instance_v2" "instance_1" {
  name            = "instance_1"
  security_groups = ["default"]
}

resource "openstack_blockstorage_volume_attach_v2" "va_1" {
  instance_id = "${openstack_compute_instance_v2.instance_1.id}"
  volume_id   = "${openstack_blockstorage_volume_v2.volume_1.id}"
  device      = "auto"
  attach_mode = "rw"
}

Argument Reference

The following arguments are supported:

region - (Required) The region in which to obtain the V2 Block Storage client. A Block Storage client is needed to create a volume attachment. If omitted, the OS_REGION_NAME environment variable is used. Changing this creates a new volume attachment.
volume_id - (Required) The ID of the Volume to attach to an Instance.
instance_id - (Required if host_name is not used) The ID of the Instance to attach the Volume to.
host_name - (Required if instance_id is not used) The host to attach the volume to.
device - (Optional) The device to attach the volume as.
attach_mode - (Optional) Specify whether to attach the volume as Read-Only (ro) or Read-Write (rw). Only values of ro and rw are accepted. If left unspecified, the Block Storage API will apply a default of rw.

Attributes Reference

The following attributes are exported:

region - See Argument Reference above.
volume_id - See Argument Reference above.
instance_id - See Argument Reference above.
host_name - See Argument Reference above.
attach_mode - See Argument Reference above.
device - See Argument Reference above. NOTE: Whether or not this is really the device the volume was attached as depends on the hypervisor being used in the OpenStack cloud. Do not consider this an authoritative piece of information.

Import

Volume Attachments can be imported using the Volume and Attachment ID separated by a slash, e.g.

$ terraform import openstack_blockstorage_volume_attach_v2.va_1 89c60255-9bd6-460c-822a-e2b959ede9d2/45670584-225f-46c3-b33e-6707b589b666
