Checkout this branch and then install the packer plugin by:

Create a file named test.pkr.hcl with the following content.

locals { timestamp = regex_replace(timestamp(), "[- TZ:]", "") }

source "linode" "example" {
  image             = "linode/debian11"
  image_description = "My Private Image"
  image_label       = "private-image-${local.timestamp}"
  instance_label    = "temporary-linode-${local.timestamp}"
  instance_type     = "g6-nanode-1"
  region            = "us-mia"
  ssh_username      = "root"

  image_regions     = ["us-mia", "in-maa", "us-ord", "us-lax", "us-sea", "jp-osa", "it-mil", "nl-ams", "se-sto"]

  interface {
    purpose = "public"
  }
}

build {
  sources = ["source.linode.example"]
}

Finally, run the build command:

packer build .

Verify the image has been replicated to the selected regions in image_regions attribute in the HCL file above.
