arvancloud_iaas_volume_attachment (Resource)

Manages the attachment of a block storage volume to a compute server instance. This resource attaches an existing volume to a server, making the volume accessible from the server. The volume must already exist and must not be attached to another server.

Example Usage​

# Create a volume
resource "arvancloud_iaas_volume" "data" {
  name              = "data-volume"
  description       = "Data storage for web application"
  size              = 50
  type              = "ssd"
  availability_zone = "ir-central1-a"
}

# Create a server
resource "arvancloud_iaas_server" "web" {
  name              = "web-server"
  flavor            = "g1-2-2"
  image             = "ubuntu-22.04"
  availability_zone = "ir-central1-a"
}

# Attach the volume to the server
resource "arvancloud_iaas_volume_attachment" "web_data" {
  volume_id         = arvancloud_iaas_volume.data.id
  server_id         = arvancloud_iaas_server.web.id
  availability_zone = "ir-central1-a"
}

# Outputs
output "attachment_id" {
  description = "Composite ID of the volume attachment"
  value       = arvancloud_iaas_volume_attachment.web_data.id
}

output "device_path" {
  description = "Device path where volume is attached (e.g., /dev/vdb)"
  value       = arvancloud_iaas_volume_attachment.web_data.device
}

output "attached_at" {
  description = "Timestamp when the volume was attached"
  value       = arvancloud_iaas_volume_attachment.web_data.attached_at
}

output "volume_status" {
  description = "Current status of the volume after attachment"
  value       = arvancloud_iaas_volume_attachment.web_data.status
}

Schema​

Required​

  • availability_zone (String) Availability zone where the volume and server reside (e.g., ir-central1-a).
  • server_id (String) ID of the compute server instance to attach the volume to.
  • volume_id (String) ID of the volume to attach.

Read-Only​

  • attached_at (String) Timestamp when the volume was attached to the server.
  • device (String) Device path where the volume is attached on the server (e.g., /dev/vdb).
  • id (String) Unique identifier for this attachment (format: {volume_id}:{server_id}).
  • status (String) Status of the volume after attachment (e.g., in-use).

Import​

Import is supported using the following syntax:

terraform import arvancloud_iaas_volume_attachment.example "ir-thr-si1:e76c3f7a-527d-4f37-ae6a-9a2b6c37f9f0:ab5f9ae1-5c5e-44e2-8923-b11ea5a6e9c2"
