Is there any way to use snapshot as an image of hcloud server?

Hi there,

First of all, thanks for your work with maintaining this plugin. I am quite new to Hetzner Cloud and would like to know if there any way to use snapshots as an image of the server, using your plugin?

Hello,
I haven't tried yet, but it should be possible by passing the snapshot ID (which is an integer) as a string to the parameter hcloud_image of this plugin.

This "gotcha" is not specific to this plugin: also if you were to use just Terraform, you would need a way to find the ID, because the name works only for Hetzner-provided images, not for user snapshots.

For example, I use Packer to build snapshots, and use a label like this:

  source "hcloud.cfg" {
    name = "core"
    snapshot_name = "myimage"
    snapshot_labels = {
      "name" : "myimage" <== HERE
    }
  }

just to be able then in Terraform to find it as:

data "hcloud_image" "myimage" {
  with_selector = "name=myimage" <== looking up the label above
}

and finally pass the ID to construct a server:

resource "hcloud_server" "foo" {
  image              = data.hcloud_image.myimage.id  <== SEE `id`
  ...

Exact same reasoning if using Pulumi.

Note that you do not need to pass via Packer. Also if you took the snapshot from the webconsole, you could add a label and then use the same Terraform (or Pulumi) logic to find it.
