To create an empty volume on Harvester with Terraform using the Harvester Terraform Provider, define a harvester_volume resource block:

resource "harvester_volume" "empty-volume" {
  name      = "empty-volume"
  namespace = "default"

  size = "10Gi"
}

Create an Image Volume

UI
API
Terraform

Header Section

Set the Volume Name.
(Optional) Provide a Description for the Volume.

Basics Tab

Choose VM Image in Source.
Select an existing Image.

Configure the Size of the volume.

When creating volumes from a VM image, ensure that the volume size is greater than or equal to the image size. The volume may become corrupted if the configured volume size is less than the size of the underlying image. This is particularly important for qcow2 images because the virtual size is typically greater than the physical size. By default, Harvester will set the volume size to the virtual size of the image.

Create a volume, initialized with the contents of the image image-8rb2z from the namespace default:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    harvesterhci.io/imageId: default/image-8rb2z
    volume.beta.kubernetes.io/storage-provisioner: driver.longhorn.io
    volume.kubernetes.io/storage-provisioner: driver.longhorn.io
  name: foobar
  namespace: default
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 5Gi
  storageClassName: longhorn-image-8rb2z
  volumeMode: Block
  volumeName: pvc-foobar

To create a volume on Harvester using Terraform and initialize it with the contents of an image, define a harvester_volume resource block and set the image property:

resource "harvester_volume" "opensuse154-image-disk" {
  name      = "opensuse154-image-disk"
  namespace = "default"

  size  = "10Gi"
  image = harvester_image.opensuse154.id
}
