@here: We need to implement the the version management for VM images. Just checking what tool and process you guys are using to store VM images (I.e. git…etc)

To store VM content? Or the config about them? We're extremely new to harvester, so we're planning on using terraform via the harvester provider to keep our configs in code.

Actually we are uploading VM images through UI. We need to manage these images in version control for Audits. Moreover we are looking a solution for 100+ images. Any advice please?

Ahh, I know you can also manage those via terraform. We're pulling in the various ubuntu/rocky cloud images that way.

variable "guest_images" {
  type = map(any)
  default = {
    "22.04-amd64"   = "<https://cloud-images.ubuntu.com/releases/jammy/release/ubuntu-22.04-server-cloudimg-amd64.img>",
    "20.04-amd64"   = "<https://cloud-images.ubuntu.com/releases/focal/release/ubuntu-20.04-server-cloudimg-amd64.img>",
    "18.04-amd64"   = "<https://cloud-images.ubuntu.com/releases/bionic/release/ubuntu-18.04-server-cloudimg-amd64.img>",
    "16.04-amd64"   = "<https://cloud-images.ubuntu.com/releases/xenial/release/ubuntu-16.04-server-cloudimg-amd64-disk1.img>",
    "rocky9-amd64"  = "<https://dl.rockylinux.org/pub/rocky/9/images/x86_64/Rocky-9-GenericCloud-9.0-20220830.0.x86_64.qcow2>",
    "centos8-amd64" = "<https://cloud.centos.org/centos/8/x86_64/images/CentOS-8-GenericCloud-8.4.2105-20210603.0.x86_64.qcow2>"
  }
}

resource "harvester_image" "guest_images" {
  for_each  = var.guest_images
  name      = each.key
  namespace = "default"

  display_name = each.key
  source_type  = "download"
  url          = each.value
}

That will create vm images in harvester from those URLs.

Thanks @miniature-hairdresser-1087: So you guys are creating "VirtualMachineImage" CRD after this loop?

Something like this?

$ cat <<EOF | kubectl apply -f - apiVersion: harvesterhci.io/v1beta1 kind: VirtualMachineImage metadata: name: image-lvqxn namespace: default spec: displayName: opensuse-leap-15.3.x86_64-nocloud.qcow2 pvcName: "" pvcNamespace: "" sourceType: download url: http://download.opensuse.org/repositories/Cloud:/Images:/Leap_15.3/images/openSUSE-Leap-15.3.x86_64-NoCloud.qcow2 EOF

The Terraform creates the VirtualMachineImage in the cluster for us with the

resource "harvester_image" "guest_images" {}

stanza.
