Managing disks and their snapshots

To create a disk volume, create a volume.tf file that describes the configuration of the volume to be created. Add the text from the example below and correct the settings for your volume. This example describes how to create a 1 GB disk volume of type ceph-ssd in the GZ1 availability zone.

To create a disk volume, you need the vkcs_blockstorage_volume resource that provides a block storage volume. You can create, modify, and delete block storage volumes.

Copy
resource "vkcs_blockstorage_volume" "volume" {  name = "volume"  description = "test volume"  metadata = {    foo = "bar"  }  size = 1  availability_zone = "GZ1"  volume_type = "ceph-ssd"}

Here:

• name: the volume name.
• description: the volume description.
• metadata: the key value map for the volume metadata.
• size: (required) the volume size in gigabytes.
• availability_zone: (required) the name of the availability zone of the data centers storing the volume.
• volume_type: (required) the volume type.

Add the text of the example to the volume.tf file and run the following commands:

Copy
terraform init

Copy
terraform apply

To create a snapshot of the state of a disk volume, create a file snapshot.tf that describes the configuration of the snapshot to be created. Add the text from the examples below and adjust the settings for your infrastructure. This example describes how to create a snapshot of a disk volume with the resource ID vkcs_blockstorage_volume.volume.id.

To create a snapshot you need the vkcs_blockstorage_snapshot resource that a block storage snapshot. You can create, modify, and delete a snapshot of a block storage volume.

Copy
resource "vkcs_blockstorage_snapshot" "snapshot" {  volume_id = "${vkcs_blockstorage_volume.volume.id}"  name = "snapshot"  description = "test snapshot"  metadata = {    foo = "bar"  }}

Here:

• volume_id: (required) the ID of the volume for which the snapshot to be created.
• name: the snapshot name.
• description: the snapshot description.
• metadata: the key value map for the volume metadata.

Add the text of the example to the snapshot.tf file and run the following commands:

Copy
terraform init

Copy
terraform apply
